USB not available HD 8 (2018) - Fire HD 8 and HD 10 Q&A, Help & Troubleshooting

Hi,
I am a bit of a Newb to the fire, but have the developer tools going and USB debugging engaged, but when the tablet is connected to either of two Win 10 computers, it does not show up as any kind of device, and in the settings of the tab the USB conneciton is greyed out (presumable because no connection is detected). The tablet charges fine, though. I tried installing fire USB drivers from a link on Amazon, but windows reported they did not install correctly (I had admin privileges too). Has anyone encountered this? My other Android devices are discovered by windows very easily. Sorry if this is obvious somehow...

Turn debugging OFF. That gets in the way of doing what you want.
Debugging is only if you need to send ADB commands to the tablet. Not for straight file transfers.
After turning it off, then your tablet will show up as a device in Windows.
But, the storage won't show up until you pull down from the top on the tablet > tap "USB charging this device" > tap "Transfer files". Then, you can click on the device in Windows and see "Internal storage", and an SD card if you have one in the tablet.
You didn't need to do this in the previous 7th get HD8. Before, it was in file transfer mode by default when you connected the USB to a PC. But the 8th gens changed that. I guess it's the difference between the older tablet OS being based on Android 5, and the new ones now based on Android 7.

Thanks, I did that, and nothing changed. When I pull down from the top, there is no USB notification (though the charging icon works and is visible at the top of the screen).

Have you tried using a different USB cable?

Yes, thanks I have, on two different win 10 computers. So I figured it was something to do with the tablet.

[Q] Any way to get USB Mass Storage instead of MTP?

Not entirely sure what kind of process might be needed, but is it at all possible to use the older method of transferring files between a computer to an Android device (USB Mass Storage) instead of MTP?
MTP (in my experience) is... not ideal in most cases. File transfers are seemingly slower, can only do one thing at a time (I think if your transferring a file, you can't even browse other folders on the MTP device), and sometimes file transfers just get stuck for no reason. Was trying to copy over a few PDF's to my N10 and it seems to just hang randomly, had to reboot the device 4 times already (twice to just create and rename a folder).
what about the option in settings -> storage -> and tap the menu button on the top right and select USB Computer connection?

I had the same problem at first, but I realized my USB ports on the front end of my PC arent USB 2.0, so I plugged it into the back, and works like a charm. Just a thought.

I already did that and tried both options (MTP & PTP), but the N10 does not show up on my computer at all in either case, with or without USB debugging. I have had no such problems with my other android devices (all still running gingerbread, in case that matters).
My N10 is rooted and my computer runs xubuntu 12.04; I don't have a window box to test... Any suggestions? Thanks!

Unfortunately the answer is no.
There was a long discussion on the Galaxy Nexus forums about it a while back.
I also wish for a usb mass storage option for compatibility with radios for playing music. They don't read mtp/ptp for any generic one I've come across.

Hmm, but what's the main thing stopping this from being possible? I thought I heard of a few JB devices that were able to get USB Mass Storage (LG Optimus G I think has a method, or whatever the phone is that has similar parts to a Nexus 4), and a Galaxy Tab I used to have had Mass Storage in ICS.
Mass storage is possible when the sdcard volume is actually a separate disk. On the Nexus 10 this is an "emulated" sdcard and cannot use USB mass storage safely because that protocol gives exclusive control to PC.
The easiest solution is to use one of the many wireless transfer apps like AirDroid.
Another option for Linux users if you really want a wired transfer is to use adbfs. This is a FUSE wrapper around the usb android debug protocol.
https://github.com/spion/adbfs-rootless
adbfs would give you seamless mounting just like USB Mass Storage.
Another solution, though not a seamless mount, is QtADB: http://qtadb.wordpress.com/
This is another wrapper around the usb android debug protocol.
Oh my god, thank you for the AirDroid recommendation. Holy crap is this program useful with my new nexus 4.

dear espionage,
i just wanted to share this with you in case it would be helpful. in fact, you might even have more technical know-how to find out how i accidentally managed this useful fix. first, the reason i was looking for this MTP to USB storage was my habit of synchronizing my thumb-drive to my desktop using any free synching software. this of course, can be only be done when the storage device is recognized as a DRIVE. unfortunately, i believe with the updating of the OS to 4.1 onwards, the USB storage option has been removed, and now only access to MTP is possible. the bad side to this is that one's device is recognized as a portable media device and this means i can no longer synch like i did before the contents of the SD card to my desktop.
second, i found the solution accidentally by installing MultiMount-SD v.2.5 into my Sony Xperia V (LT25i). accidentally i say, because when i clicked on it for the first time, it wouldn't work. it showed a help tip saying that i should trying enabling what it called an MTP fix provided by the program. i did this, restarted the program and guess what happened. there occurred a looping sequence (i guess unending) device recognition-mount and unmount (the PC sounded this off many times), since there was no end to it, i decided to UNINSTALL the program even while the recognition loop was going on. in the meantime one could see a drive appearing in the EXPLORER with a (?), then it would appear with an assigned drive letter, then finally disappear, and so on.
i successfully uninstalled the MultiMount apk, and surprisingly even with the message that the device wasn't properly recognized or installed, i could now connect my Xperia and it mounts as a USB storage device and no longer MTP. to test this 'accident', i tried connecting it to my desktop, running Windows 7, and it worked without any hitches! I don't really mind losing the MTP option, sides it's very limited in its connectivity with the PC. Another bonus, is despite this, i can still communicate with my device through the MyPhoneExplorer program that allows one to send text messages and other stuff. This was one wonderful accident.
oh, one last thing, even with rebooting my phone, the setup seems to have become a 'permanent fix'. now, when the device is connected one sees in the activated portions in the top menu saying: USB Storage - SD card connected to PC. This was never there before... And i wonder what MultiMountSD must have left permanently to allow my Xperia V to now connect as USB storage. Yahoo!!!
i hope though, you could see what the technical side of this accident is, so that somehow something more stable could be done or programmed without having to go through the 'accidental' procedure i have detailed above.
ciao,

I had this issue with Ubuntu 12.04 too, after I updated to 13.04 it started to work like a charm . You can also try changing the rules in your PC, you can find how to do it in the Google website .

Thanks SmokinCharger! I guess it's quite clear that attempts to allow certain devices to be read in USB Storage mode is a hardware configuration. If your device isn't designed for it, then it won't be able to do this. It's like wanting your volkswagen to have a 6th gear... thus, what was posted previously is true:

*I also would like to apologize what i've posted earlier regarding my accidental discovery with Multi-Mount SD. What the app actually did was to access a feature in my device (rooted Xperia V LT125i) which i wasn't aware of. All the time, my device was actually configured to have both MTP and USB Storage.:silly:
So for such devices that are hardware configured only to be MTP or PTP, the only 'solution' or 'alternative' would be to "ROOT" them and set them up with OTG (On the Go) USB access. This may have some hitches, but i've been using this quite a lot. Sometimes though, a RESET is required so that explorer applications would function normally.
Thanks again. I guess this will be all for now in our attempts to reconfigure something that is hardware defined in certain devices.

You're welcome. Chainfire is a great and well known developer that has development many great apps including Stickmount. Look it up in Play especially the Pro version, which is "The price is aimed at being approximately one beer at the bar ". It works with mounting the UBS OTG. The Pro will automatically mount and unmount.

Why does my Nexus only show up on my PC once out of like every 5 times I plug it in?

I have the correct drivers on my PC and its not a big deal because I'm only plugging it in to charge it..but when the little 'windows explorer' pops up..about once out of every 5 or 10 times do I actually see the phone and can browse directories and copy stuff.
the rest of the time the explorer window is 'blank' when it pops up.
like i said..it doesnt really bother me because i haven't had a reason to need it showing up reliably on my desktop..just curious if this has happened to anyone else.
FYI, the phone screen always says "connected as a media device" regardless of whether its showing up on my Win 7 PC desktop or not.
Disable USB Debugging in the Developer Options when you want to browse the phone. With it enabled I sometimes cannot browse either on my PC.

Yep, disabling it makes MTP work every time, with it enabled it gets iffy.

I think my "issue" is on my XP laptop. On Win7 desktop (using the same drivers from that link) I have no problems with mtp and usb debugging on. Good catch!
cool tip!!! i'll install those drivers.
PS do they work with ALL android devices? my kids have 2 tmobile 'mytouch' android phones i just bought off ebay and the drivers i've used are pretty picky as well.
I also had an issue with USB Debugging on with no functioning MTP on Windows XP. I solved it and documented it with a post over in the N7 forums (reading the posts clued me in):
http://forum.xda-developers.com/showpost.php?p=35667806&postcount=23
Windows 7 has native support for MTP so it most likely will never see these issues -- although there are a few exceptions.

Absolutely cannot get my Moto G4 Plus to connect to my PC or Mac

Greetings,
Recently purchased a Moto G4 Plus 4GB / 64GB from Amazon and absolutely cannot get it to connect to either of my 2 PC computers or my Macbook Pro. When I plug in the USB cable and unlock the phone screen windows gives the familiar "usb device connected" chime, correctly identifies that a Moto G4 has been plugged in, and begins to automatically install drivers/software. Once the installation is complete however, the phone does not show up in My Computer. It is listed in the device manager under "other devices" as a Moto G4 but with a yellow exclamation mark. Right clicking and selecting properties shows that there is "no device driver installed" and "no compatible device drivers available."
I have tried dragging down the tray on my phone screen and switching from "Charging" to "File transfers" as well as all of the other options. Toggling between USB modes causes Windows to chime the familiar "usb device disconnected" chime but nothing happens. I have tried multiple USB cables, including the one that came with the phone. I have tried right clicking and uninstalling the device from the device manager, installing the latest USB drivers from the Motorola website, and plugging the phone back in - still no success. I have even tried this on a completely different machine running Windows 10 as well as a Macbook Pro running OSX - all with the same results. At this point I am inclined to think that there is something wrong with my phone. Any suggestions?
Thanks,
Greg

My PC doesn't recognize my Nexus 7 2013

I have an Asus Nexus 7 tablet that over a year ago I rooted and flashed and maybe a few other things, I don't fully remember, but I did get it to run the Nitrogen OS successfully, and since then I've used it with no problems. But the other day I plugged it into my PC via USB cable as I always do when I want to load a movie or whatever, and this time my PC refused to have anything to do with it. Immediately upon plugging it into my desktop's USB 3.0 (2.0 port does the same thing) I get this Windows 10 notification: "USB Device Not Recognized. The last USB device you connected to this computer has malfunctioned and Windows does not recognize it." When I check under Device Manager I see a yellow triangle warning under Universal Serial Bus controllers that says, "Unknown USB Device (Device Descriptor Request Failed)." And that's as far as I can go. There is no mention of ASUS, Nexus, or Android anywhere else in Device Manager. I've checked under all the headings.
It seems Windows 10 knows something has been connected when I plug in via USB but it doesn't know what to do with the device. I've searched the Internet high and low for a solution but nothing works. Here's what I've tried:
1) Uninstalled the yellow triangle error driver from Device Manager, checked for new hardware, got the yellow triangle back.
2) Tried updating driver but "You have the latest driver installed."
3) Tried installing USB driver from Google and "the operation completed successfully" but the problem remains even after reboot.
4) Went to Developer Options and ensured USB debugging is turned on and MTP is selected in USB Configuration. When I turn USB Debugging on and off with the Nexus connected via USB, Windows 10 reacts, but only to tell me with each change that I have an "unknown USB device attached," basically all the original error messages. I get the same errors whether I'm set for MTP or Camera or charge only or any of the other options.
5) Learned others have found a bad cable can cause my problem so I located three spare cables around the house and none worked. So I ordered a fresh new data cable from Amazon which arrived today -- but the problem remains.
6) I have a triple-boot PC. All three OS installations are Win10 but installed separately on different drives -- one of them is from the Microsoft Insider program, so should be the latest and greatest -- but I have the exact same problem on all three.
7) Wondered if maybe Linux would work so tried Knoppix live boot disk and even did a full installation of Zorin on a separate HDD. Neither version of Linux recognized that any Android device was attached. I even ran a "find-mtp" Linux program but it saw nothing.
8) Installed Wondershare Mobile Go and Syncios Data Transfer -- both are programs for dealing with Android devices via USB on a PC -- and neither sees my Nexus. And I guess there's no way they could as the Nexus doesn't appear in Device Manager.
8) Reset the Nexus to factory settings. All my apps and so forth are gone but the problem remains exactly the same.
I've been at this for about a week now so there are probably other things I've tried and forgotten about but nothing has worked. If I had another Android device I'd see if the computer recognizes it via USB but I don't have one. Maybe I can get a friend to help me out. I'm grasping at straws.
One more thing -- I don't remember whether I've ever before communicated with this Nexus on my current computer. In May of this year my old Asus MBO failed and I've built a new computer around an Asus Prime X299-A. It's working great, its USB ports are giving me no problems with anything else I throw at them, but I'm wondering of maybe I've got something set wrong in BIOS (UEFI). I've gone through every USB setting I can find in BIOS and no changes offered seem appropriate. But I've tried them this way and that with no apparent effect. And as I said, USB 3.0 and 2.0 are working great for everything else.
And when I wrote that last paragraph it hit me that I should try the spare PC I keep in a closet. Duh. So,
9) Tried a different PC, a spare Win10 system I built from spare parts from my old system plus an el cheapo MBO. This is a TOTALLY DIFFERENT COMPUTER -- but the problem is exactly the same.
It can't be the Nitrogen OS -- I just can't go there. It's been working perfectly for over a year, no glitches whatsoever. How could it suddenly decide to stop connecting via USB? I've pulled all my hair -- totally bald now, but that didn't work either. Any other ideas? Anybody? Toss the Nexus in the trash? That would be no fun. And it does work, though with the factory reset I've erased all the kids movies I was keeping on it for the young ones who occasionally visit and I have no way to put them back. I dunno what to try next ....
Other things to try
Windows 7 or better yet XP
Disable your anti-virus on your pc
Make sure usb debugging turned on for the tablet.
Use an app like drivedroid to see what usb setting work with your phone. (Not what the app is meant for, but the settings wizard is pretty helpful.)
Worst case:
Use the Nexus Root Kit to unroot and return the device to factory image, then reroot and install latest twrp and image of your choice.

My Nexus 7 2013 connects straight up With Windows 7 Professional on a Lenova M92p "desktop". The Nexus is set via Developer Options for USB Configuration of "MTP (Media Transfer Protocol)". Upon plugging in the Nexus to the Win 7 machine, on the Nexus you swipe down to see a menu for USB options, which defaults to Charging. Then you set it to File Transfers, and Windows autoplay then asks what you want to do, one option of which is "Open Device to View Files". That is Windows 7, which works! In Windows 7 the Nexus 7 appears in Device Manager under Portable Devices.
Windows 10 Professional, which I have on my XPS 13 9370, does not even acknowledge that there is a device connected under Portable Devices. Under Unknown Devices, when right-clicking to Update Driver and choosing among those for Portable Devices, there are many MTP devices from 4 manufacturers including Microsoft (including Kodak 4800 Digital Camera) but none of them load. I get "The device cannot start. (Code 10)". I've read that the correct one is "MTP USB Device" but neither that one nor any MTP device driver loads. Stuck!!

I replied earlier but being lazy I didn't log in so here we go again so you'll see I'm the OP. My Win10 Pro desktop recognizes my Nexus 7 nicely since I halfway pried the back off the Nexus and then snapped it back in place. Yep, that's all it took. Apparently something was loose or misaligned inside the Nexus and just fiddling with it fixed it. Yay.

Your issue is not similar to the OP who had no connectivity at all in different PCs.
The issue is the driver in your case, may be a clash of drivers. Install USBDview in the PC and using it, uninstall every driver related to USB. Don't worry, since Windows will reinstall any driver needed as and when the peripherals are connected. Restart the PC and disable 'driver signing' and any antivirus program including Windows Defender. Now connect the tab and check if the correct drivers are installed and the tab is recognised. If not, try to update the driver in Device Manager. If even that doesn't work, you may have to reinstall Windows.

Onn 7" SURF Model 100071481 GEN. 3 -Go Edition

I made the mistake of buying this tablet, so -thanks- Walmart for the unexpected, unwelcome headaches.
I got it for reading ebooks, because of the slightly larger screen compared to my phone. I saw it was limited when I got it home and turned it on, but I was still able to install a couple of book-reader apps so I thought it would be OK for my purposes. But when I plug it into my Windows 11 laptop with the USB cable the tablet doesn't show up on the computer. I have books on the laptop to transfer over.
Is there any way I can force the USB to be a data transfer connection instead of only a battery charger? There is no "use USB for" option when it's plugged in, like there is on my phone. Is there maybe a third party app I could install that will enable this -usually- normal function? Thanks, any advice and help is appreciated!
Hi @Lookstwice
Enable MTP:
Settings > Connected devices > USB > File transfer
Enable ADB:
Settings > About Tablet > Build number (7 x tap)
Settings > System > Advanced > USB debugging
Some people like Calibre on their desktop for organizing books. I believe that understands MTP.
Me, I use my adbsync.exe (in my sig) to synchronize directories. It uses ADB (duh).
Also check out this thread on the 8" which has some info that may be applicable:
https://forum.xda-developers.com/t/new-generation-3-onn-tablets-are-now-available.4464147/
Hello Renate and thanks for the advice!
I did find the developer mode and turned on USB debugging. Also, I selected File Transfer under Default USB Configuration.
Under Settings > Connected devices there is no USB on my tablet, only +Pair New Device and Connection preferences, Bluetooth.
The tablet still doesn't show up at all, when I connect via USB to my laptop.
Is there anything else I should try? Under System > Developer options maybe? How about OEM Unlocking? Disable adb authorization timeout? Thanks!
Are you sure that you have a data cable? Cheesy ones only supply power.
If you're connected to Windows enabling/disabling USB debugging should make it "bong".
To check out if I am using an inferior cable, I switched to my cellphone cable. It works fine on my cell, but no luck with this tablet. I know it makes no sense!
Thanks for your help anyway. I'm open to any ideas.

Sorry, I missed your response.
These devices come up in the MTK preloader whenever they reboot.
You don't actually need to load a loader or do anything.
Connect the USB. I presume you're using Windows? Does it "bong"?
Use the regular Android reboot option on the power menu.
Does it do a bunch of bong-ing and Windows flashes popups complaining about devices?
You may have a hardware problem and you need to return the device.
Wow, Renate, you've got some serious skills. Pretty impressive to turn such a low-end device into a custom machine...
I'm having trouble pulling the boot.img from this device... If anyone was willing to share the stock boot.img for the 100071481 that would be SUPER appreciated...
otherwise I'm just going to keep trying to get this MTK client thing to work although nothing seems to get the device to be visible...
Joined the forum to post this message though I hope to contribute in the future! Thanks!
@oneiromon Yes, try the (Python) MTK client
I've had problems getting that to run under Windows. I finally used a Raspberry Pi with Linux.
I was working on writing a native Windows MTK client but I haven't got that working yet.
After successfully writing a native Windows EDL (Qualcomm) client it was a bit disheartening to dive into the MediaTek gobble-dee-gook.
FWIW: I've not had luck with fastboot boot whatever.img
It works fine with fastboot flash boot whatever.img, then fastboot reset
@Renate - THANKS! for all your help with this onn tablet . Sorry I've not been keeping current on responses. I use the tablet to read books on while getting medical treatments and I was able to upload the files to my Google drive and then download to the tablet.
I'm on a Windows 11 laptop and it doesn't "bong" when I attach the tablet. I'll try the reboot option and let y'all know .
@oneiromon - I totally agree with this statement: "Wow, Renate, you've got some serious skills."
@Lookstwice I haven't got up to Windows 11, so maybe it's hiding some stuff from you.
It could also be that the 7" has some differences to the 8"
The USB/VID of my 8" is 0e8d/201c (MediaTek)
Try using UsbView.exe
See if anything appears/disappears as you plug in. For sanity, check against a known working device.
Oh, and if you're thinking reading, you really ought to consider Eink devices.
Yeah, a lot of them are annoying and underpowered, but see if you like the concept first.
I like the Onyx Poke3, but buttons/no buttons is contentious and personal.
I use no buttons but a tiny Bluetooth clicker. I love it!
