[HELP!] USB storage not working properly - myTouch 4G Q&A, Help & Troubleshooting

I don't know what happened, but I can no longer mount the SD card via USB. I've spent half the afternoon trying to fix the drivers, and I end up in the exact same place I was before.
I'm running Windows 7 64-bit and CyanogenMod 6 RC2 on the phone. I have ADB set up and, to my knowledge, the drivers for it are working. ADB devices recognized my phone.
When I try to mount the SD card, the phone shows "USB storage in use," but it doesn't show up on my computer. Normally I get a little popup asking if I want to open the folder to view files. In Device Manager, it shows a little warning on USB Mass Storage Device which I believe is the phone. If I right-click and go to Properties, is says "This device cannot start. (Code10)" (see first thumbnail).
Here's the weird part: If I boot into recovery and select to mount the storage card, it will mount (see second thumbnail).
Can anyone help me? Thanks in advance.

Did you try it with a different card? Or this card in card reader? You have to rule out simple things first, like weird card corruption.

I've tried a different card. No difference.

I uninstalled all the drivers and restarted my computer. When I plugged the phone in, I got the following message. Something called MTP did not install successfully. Anyone know what to do about this?

Well, after numerous cycles of uninstalling and attempting to reinstall the drivers, I still had no idea what the problem was. I uninstalled all the drivers and ran a utility on my PC to clean and fix problems in the registry. I rebooted it and then plugged the phone in. It installed the drivers and now both ADB and USB storage work.
Strange thing is, I don't see an entry for Android ADB Interface in the device manager any more. I see Android USB Drivers and the USB Mass Storage though, so I guess that's all it needs.

Can't Mount SD Card

Hey Everyone,
I apologise if this is in the wrong forum (not sure if it should be in Android Development), and before I start I want to make it clear that I DID use the search function, I searched for "Can't Enable USB Mass Storage" and "No option to mount SD Card" with no relevant results.
Rom: JFv1.51 CRB43-EU
Ok, I was using my phone fine I managed to sync around 12GB worth of music and transfer a few files last night (I flashed the ROM around 20:00 GMT after trying out several hero builds).
This morning I mounted the SD Card to my laptop (OS is Windows 7 RC1) and transferred a few APK's. Suddenly as I was in the market the phone comes up with "Checking SD Card for Errors" and had for some reason unmounted itself from the PC.
Now when I plug in the USB cable all I get is the light to indicate it's charging. There's no option to mount the SD Card. I've tried it on my Laptop, My Vista Desktop AND My Xbox 360 (usually there's a mount option when you connect to that which allows the xbox to see music on the phone).
Strangest thing is the MicroSD Card seems fine, I am able to play my music and see the 2 pictures I have stored on it. Another site suggested using Anycut to make a shortcut to SD CArd and then ticking Enable USB Mass Storage. This doesn't work either, I get a ! in a triangle in the status bar saying USB Mass Storage Enabled but neither my laptop or my desktop will pick it up.
Any Suggestions?
Thanks,
Steve.

Yep, Should it be?
Yes it should be. Try uninstalling and reinstalling the drivers (USB mass storage devices)

Cant mount sd card on the computer

I hate to start a "OMG ITS NOT WORKING" Thread. But im just plain stuck.
Im trying to get to my sd card on my computer, to switch to my 4gb and to get the update.zip on it so i can root. But no matter what i do, it wont mount. My computer complains that the "USB Device not recognized" and loads a bogus driver. Ive been trying to get it figured out but nothing so far.
Anyone else have this problem? Any one know how to fix it?
hope this helps

No help :O( i dont get whats wrong.
what happens when you plug in the usb cord? Are any external drives shown on your computers file/drive viewer (my computer, etc)? If so can you open those drives, if not what does it say?
the way it should work is.
-DL the drivers here - http://forum.xda-developers.com/showthread.php?p=7218057
-install the drivers on your PC
-hookup phone to PC via the provided usb cable
-on the phone drop down the notification bar and MOUNT the SD card.
-open My Computer or other file viewer
-see two external drives one the internal with about 13GB of total space and one the SD card with 2GB of total space
-add remove files from cards
I did all that. When i plug it in, my computer says "the usb device is not recognized" and proceeds to load a bogus driver. Ive installed the debugging driver, nothing. nothing shows up in my computer for the sd card, OR the phones own flash memory.
I have 3 separate android phones, never had this problem before.
try connecting the phone to your pc again. Make sure that on your phone, that youre using the mass-storage option. Next look at the top of your phone, and pull down the header bar. and click on the "usb connected" option or whatever it says, and then choose "mount" when it pops up.
That's how your actually turn on the mass-storage. dont know why its like this, thought it would be automatically done after chosing the mass-storage option.
I am having the same issue. Installed drivers but can't access the drives.
It does automatically set it self for mass storage, but the computer for some reason isnt seeing it. im pretty sure its a driver issue. or the usb port on the phone maybe bad... that would be annoying.

Usb problem

Hello! (first post , have been reading for a while though)
I can't connect the phone to my PC (win7 64bit), not as a mass storage device or with Kies (it worked fine before with my home PC and an XP machine at work).
It stopped working after the PC said "Device drivers installed properly" (or something like that) when I connected it, after that I have'nt been able to make it work as mass storage device on any computer..
Very strange and very annoying!
I'm thinking I might factory reset the phone (would very anti-nice though to loose all apps and stuff), so I thought I'd ask here first if there are any possible solutions..
Thx!
if you open device manager in Win7 x64 do you see it listed as GT-I9000 in Portable Devices ?
that's what it shows in mine, and i'm on x64 Win7
it automatically opens in Mass Storage also works in Kies
WEE!! Got it to work just now!!
Rebooted the phone (as I do every day) and connected it to charge over night, and windows popped up with the "installing device driver blabla dialogue" and suddenly it works!?!
This after not working for at least a week on any computer...
I have no idea what might have caused it, but I'm just happy it works again
Still, very strange...
It shows up in the device manager now, it did'nt before.. Thx for the reply!
On Win XP
is there a certain driver i have to download before using USB Mass Storage option.
all i get are two removable drives icon. but they can't be opened
you should only have 1 removeable device icon, 2 if you have a micro SD card inserted.
if you configure the phone to ask you what to do with the usb during connection, then you can select Kies or Mass Storage
regardless both works fine
i do have two removable drives because of the addition of the sd card
its set on Mass Storage. but it still won't open. im not sure if Windows installed it properly though
the driver details:
driver files- system32\drivers\USBSTOR.sys
does it shows in device manager, as mentioned above ?

After connecting the phone via USB, did tell the phone to Mount the drives?
anyone else encountered this issue?
Is anyone else having trouble connecting their Galaxy to a PC? I don't know whether mine is faulty or not. Downloaded the Samsung Kies software but when I plug in the Galaxy Windows is unable to find a MTP USB device driver and the phone refuses to connect. This happens Windows 7 Home Premium 64bit. Also the Galaxy has a complete fit and keeps flashing between the home screen and MTP application screen while it's connected (wxw.youtube.com/watch?v=R9hdpJPCP-k). And I don't get the usual Android option to mount for file transfer. Am I missing something?

finally managed to fix tis stupid kies connection problem...if anyone encountering the same issue jus do a factory restore n format ur internal sd card

[Q] Sideloading/accessing folders in SD

I have built an SD bootable CM7 card as described by verygreen, but when I try to create folders on that drive from my PC (filled with APK files) I can't see them on the Nook. I have no problem doing this on my rooted emmc Nook, but when I boot to an SD card (that I am setting up for my daughter's Nook) I can't access any other folders/files.
What am I doing wrong? (The box is checked allowing Unknown Sources and I am currently running 177).
Are you connecting the nook via USB or putting the SD card in your computer directly?
Sent from my NookColor using Tapatalk
The card is placed in a usb card reader (or a usd card reader), either one sees the files on the PC, but it will not find it on the nook. Even when I create a folder on the nook and move the disk over and copy a file into the new folder I can't see it on the nook.
You need to connect through the nook

This is because the partition the computer sees is the boot partition... to access it in the nook... either in terminal or adb shell:
1. mkdir /sdcard/boot
2. mount /dev/block/mmcblk1p1 /sdcard/boot/
the items on the boot partition of the SD (including the folders and apks you put there) will be visible as /sdcard/boot
Pretty sure you'd have found it in the VG SASD thread and a few others... since I have posted this several times.
Thanks for the response. I'm not real familiar with ADB so I tried it with terminal and was able to create a directory but mounting gave me a 'permission denied' message.
(Sorry if this is old info, I've spent the morning combing the SASD thread and haven't found it yet, just too much info, thanks for taking the time to help some of us who are slower learners!)
Edit: learning slowly, used su to get into superuser (#) and made directory, but when I try to mount it says not found.

If you asked this question 2 weeks ago, I might able to give you the exact answer but since I wiped out the uSD CM7, I can't remember correctly what would happen.
However, based on my experience (+/- my memory loss), what you describe is all correct and that's what it is. Odd? Maybe, but don't panic.
Let's go slowly
when I try to create folders on that drive from my PC
Click to expand...
Click to collapse
you meant you created a folder in the "boot" partition on the uSD card?
a. if so, it's not recommended. Using the left over FAT32 partition instead
b. if so, try to use Root Folder app (it's a paid app) to access root folder (boot partition) directly on the NOOK. If you see the folder you created earlier, move it to the eMMC storage.
c. if not, pls tell us more
Yes, the SD card was accessed on my PC thru a USB adapter and a folder called 'APKs' was created in the boot sector. (I have also tried just adding the files into one of the other folders, but anything I add is invisible to the Nook).
So if I need to create a folder in other than the boot sector, I would need to use something like Easeus Partition Master to make that sector active and then create the folder and add appropriate files? (When I rooted my Nook directly to emmc it sure seemed a lot easier to access folders created by my PC.)
(Thanks again for all your help.)
That's much clearer, m8
Now, I think it's easier to get straighten.
1. From PC, using SD slot or usb-sd adapter, move (remove) the "APKs" folder off your NC to your PC, save it there, then eject the uSD off PC.
2. Insert the uSD into the NC and turn it on, make sure it boots into CM7 properly.
3. Wait until it completely load. Now using usb cable to connect the NC and the PC.
4. Watch the notification status bar on the NC, tap on it then turn on usb mass storage.
5. PC should recognize the NC and ready for use.
6. Move your "APKs" folder from PC into your uSD (it would probably named as CM7SDCARD)
Update: on item 6, I prefer to move the folder to the eMMC storage. I'm not 110% sure if the NC see "it" (it means the left-over FAT32 partition on the uSD card) or not, but I do believe, 99% it will.
Deleted folder on SD card (from PC) and verified reboot ok.
Connected USB cable to PC then to Nook, no notification bar comes up, but battery icon shows charging as well as the lighted n on the cable.
Tried to use Nook Tweaks to begin USB connection (both boxes checked).
Still no recognition from the PC that anything is connected.
Edit: I am using my rooted Nook to build this SD card for my daughter's new unrooted Nook and when I plug the rooted Nook into the PC I don't get any verification from the PC on it either. No change on the Nook either, just the charging light and icon indicator.

I don't have the NC with me now so I don't know what "both boxes" are and need to be checked or not.
The USB Settings from Nook Tweaks has a "USB Host Mode" (to enable host mode to connect peripherals) and an "External VBus" (to allow charging and hosting).
Both boxes were checked.
I've read that some of these issues can be caused by a faulty cable. If so, are there other alternatives to connecting thru the cable to open this up.
I have also tried the MiniTool partition program but I have not been successful in getting the active partition to 'stick' . (It immediately reverts back to the root being active after I apply the changes.)
You definitely have to UNCHECK the "USB Host Mode".
I'm not so sure with the "External VBus" status but suggest leave it by default.
With nothing checked in the Nook Tweaks section, USB cable connected to the Nook and then the PC, there is no recognition or acknowledgment that the Nook is there from the PC. (This is true whether I use my rooted version or try after booting to the sd card.)
If it is a cable problem, I will need to replace that, but aren't there other ways to make the sd card usable?
I've tried making the 4th partition action using Minitool and also Easeus but it didn't work. (Minitool just reverts back to boot partition active immediately after I apply the changes.)
Slow down, MiniTool and partitioning have nothing to do with this. Don't make more mess.
a. when plugging NC to PC, do you see any indication on the NC's status bar? like usb debugging?
b. when plugging NC to PC, do you see any indication on the PC (running Windows)? like removable drive?
There is no indication on the PC of any new connection.
The only indication on the Nook is the lighted n at the end of the cable and the recharging icon in the status bar.
Edit: the reason I was providing info on the MiniTools experience I was having is because my original question was how to access a folder (and files) created on my sd-bootable disk on my PC but the Nook can't see it. One way to accomplish this is to write the folder/apks directly to the Nook thru the USB cable. Other alternatives are to use windows to access it on my PC but I need to be able to access the 4th partition (if my reading of the various posts is correct). MiniTools and Easeus are two options that allow you to activate the 4th partition but it has not worked for my yet.
The USB cable connection problem appears to be there whether I boot to emmc or to sd.
Edit: I was able to find a non-nook cable (for my Blackberry) and using it my Nook recognizes when I connect to the PC and executes the USB Mass Storage Utility which allows me to turn USB storage on/off. Unfortunately the PC doesn't add any new logical drives in My Computer. The device manager shows 2 B&N Ereader Disk USB devices but with the yellow ! by them.
The 4th partition you mentioned about should be taken care during the installation, using verygreen's instructions, if you do correctly. There is ABSOLUTELY no need to mess around with MiniTool or the a-like.
Another question, have you turn on the USB Debugging feature? (I don't remember where, NC not with me now). If it not, check it box, try to plug in PC using usb cable again. I expect at least the usb debugging indicator will lit up.
I checked the debug feature (part of settings/applications/development/) and it was not checked. I checked it and now I get the robot icon (USB debugging conntected) and the USB icon to toggle storage on/off. Still nothing in My Computer and the drives shown in device manager are still yellow ! .
The device manager says "This device cannot start. (Code 10)"
I know it would be too early to say but I gonna to say anyway "congratulation".
When you see those icons on the NC status bar, it's 99% that it would work.
Now, back to the reality.
1. Connect usb cable between NC and PC running Windows
2. As you can see those icons, tap on the status bar to bring up then tap on "USB Mass Storage" (or something like "connect to computer for file/folder transfer, NOT the debugging). Read the warning then tap to enable USB connection
3. Now, pay attention on the PC, if it goes smoothly as expect, by now, you now can access both storages (eMMC and left-over of the uSD card) from PC. If so, move your "APKs" folder over.
I wish you luck
1- cable connected, icons on nook show up
2- tapping on status bar gives access to USB Mass Storage utility and option to turn on/off USB storage - with USB storage set to 'on' there is no recognition on the PC
Device manager shows two entries under disk drives for B&N Ebook Disk USB device but both are tagged with yellow ! (which a right click shows "This device cannot start. Code 10")
Is there something I need to do to download a usable driver for this?
(OBTW thank you for your help and patience)
Edit: within device manager I uninstalled the two drives (while the nook was still connected and USB active) and then had it search for new hardware. This time it loaded the drivers and NO yellow ! . At that point the PC recognized the drives and I have been able to create a folder that is accessible by the Nook and the PC. Thank you for help in this.
I have also contacted B&N and have a replacement cable on the way (which seemed to be a large part of my problems). Thanks Votinh for sticking with me while I got this resolved.

[Q] USB Device Not Recognized ??

Has anyone else had this problem? When I plug my TPT into my desktop PC, running Windows 7 64 bit, I get a USB not recognized error. I have to press the white button next to the SD card slot, and reboot the tablet for it to be recognized. Once I do this, everything works properly. I can then mount the SD card, and ADB shell works. I have tried this on two different computers running the same OS, and I get the same error on both. I have the current drivers installed. Is this a tablet or a PC issue?
Is there a fix for this?
