W7 PC won't see rooted NC anymore

I rooted my NC from 1.1.0 using autonooter awhile ago and it works pretty well in general. I used to be able to hook it up to my home PC (w7) and my work PC (XP) with no problems. ADB worked (usually), the drives showed up, etc.
Everything still works on the work PC, and another W7 PC I tried it on.
Now, for some reason, neither the NC nor its SD card show up on my home PC when I plug it in! The NC shows the normal "USB Mode" screen when I plug it in, and my PC makes the USB Ding sound. But no new drives show up.
The only thing I can think of that changed is around the time it stopped working, I replaced my old USB Card reader with a new one (old one didn't work with SDHC). I also renamed some drive letters to reorganize them, since the card reader always shows 4 drive letters in windows.
I don't see the USB controller entry for the NC that I used to see in Device Manager either.

Check for NookcolorUMS app

I was having some bizarre connection issues with my PC, too, and they seem to have been corrected (at least they haven't recurred) by using a USB extension cable. It makes no sense, and I didn't do it to attempt a fix, but just noticed that the issues seemed worst when plugging into the top-side 'convenience' USB ports, and had an extra extension cable sitting around, so I plugged that into a rear port to make access less awkward. Since then, the PC consistently mounts everything just like it should.
I'm still using the NC's data cable, just plugging it into a maybe 1' extension cable rather than directly in the slot.

my XP based computer won't see the rooted NC either, however I will have to try using a port on the motherboard as opposed to one of the front mounts and see if that does the trick. I just kinda gave up on it as I didn't really need it too bad (I only use my nook for email, web browsing, and to control my DVR).

Well I unrooted my NC as I had planned anyway to upgrade to 1.2, but the problem hasn't gone away.
I tried plugging into an extension cable I have that goes directly to a MoBo rear port, but no change.
I can't run the nookcolorUMS now that I'm unrooted. Maybe I'll try it when I re-root eventually.
The thing is, it works on every other computer, so I can't figure out why it would stop working on just this one. It seems like it must be a windows issue, but I'll be damned if I can figure out what it is.

I don't bother with usb
USB connectivity is so unreliable that I don't even bother with it.
To move files around I use File Expert/network to access the PC via wireless from the device.
It's easy, reliable, and FAST.

That's a good tip. Unfortunately you have to use USB for certain functions, like manual nooting, or synching with Calibre (I suspect).
Once I'm rooted again I'll probably start using wireless for small stuff, but if I'm moving a gigabyte movie over, I'm not sure how long that will take, or how much battery it will use.

Does anything come up in device manager when you connect it? If so, did you try deleting anything that does come up, disconnect and start over? Worth a shot....

You don't have to guess--if you see a USB device that might be the NC, open properties>details and from the dropdown choose "hardware ids." If the number 2080 is in the id, it's the NC.

Nothing new comes up in device manager when I plug it in. It used to...

I experienced a similar issue and this was what causing it.
1. I have 2 front USB connections (nothing connected to either)
2. External Power USB hub connected to a rear USB slot
On Win 7, whenever I plug-in the NC via USB, I got a device not recognize error. I tried plugging it into different ports and pretty much either got no detection or device not recognize. Here is the kicker, as soon as I plug it into the usb hub, window recognize and mount it right away. This also happen to be true if I remove the usb hub altogether.

[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.

[Q] Apoligies if repeat Q: will a usb hub work with Nexus 7?

I had read in some other random forum that if you have rooted your Nexus 7, which I have, and run app "StickMount" you can connect a usb thumb drive to the nexus and give yourself more space, even install apps to the USB drive to run from. I am wondering (and am going to test it out later this evening) if anyone has tried connecting a USB hub, so that you can have say 4 ports to add different drives or game controllers/whatever else and android will recognize the different devices?
As a realist, I'm just hoping the single USB stick connection will actually work as a storage expansion area, as we all know there is no micro SD slot. I actually have an old college friend I keep in touch with who works on the Nexus development team, who had no good answer as to why micro SD was removed, as well as the ability on devices with a micro SD no longer allow the installation of apps to the sd card. I was pretty convinced it was simply because the OEMs decided to name their internal memory /mnt/sdcard which used to be the external card's mount point name, but I'm told it is more complicated than that. Am I the only one that really feels like no apps to the SD in ICS or jellybean, is quite a downgrade? I understand we can use the "cloud" now ... but that's simply not the same, and surely not as fast as a local drive (maybe?) I then proceeded to yell at him to not let the group of stupid consumers influence the great features that the half-brained+ consumers know how to properly use, to no avail. Using the micro to full USB port to mount a thumb drive seemed to be the best way to add more storage locally. Thoughts? Thanks

There are actually a whole slew of these that are even free, most require root however, which I recommend using the program with GUI interface developed specifically to unlock the bootloader, and then root the nexus 7. I think it was called Root_Toolbox or something like that. I am not at home or I would report back the official name. If anyone wants it just let me know. Thank you!

A hub works great. I've had 3 flash sticks mounted at once along with a mouse and everything has worked without a hitch.
The caveat here is to ensure you're not pulling too much current - the OTG max current source spec is alot less than the 500mA a normal USB PC host port is able to source.

Nexus 4 to Nexus 10 USB transfer, without intermediates?

The back story
I got a moga pro and now I'm playing big games on my N4, problem is, I can only play one at a time due to my limited storage. I am trying to transfer Vice City 1.4GB using usb, which transfers at 20mb/s on my computer using USB. I am trying to replicate that on my Nexus 10, so far no luck.
What I've tried
DriveDroid https://play.google.com/store/apps/details?id=com.softwarebakery.drivedroid
StickMount https://play.google.com/store/apps/details?id=eu.chainfire.stickmount
USB Sharer https://play.google.com/store/apps/details?id=os.devwom.usbsharereval
My first attempt was with DriveDroid, which was designed to turn your phone into a dynamic bootable USB for linux ISO's. It allows you to make IMG's and share them as a USB Mass Storage Device. Using an OTG cable and StickMount on my N10, I was able to move files from my N10 to my N4 over USB. Problem is, that IMG has so far been unreadable by every extraction program I've tried, including Nandroid Browser and ISO Extractor. More importantly, the IMG would take up 2GB on my N4. If I can't mount it as a directory, than that would leave no way of giving those 2GB to an app. I tried flipping it around and putting the 2GB IMG file on the N10, but then the N4 couldn't mounted due to its notorious power issues. Even if I get a powered OTG adapter for the N4, that would still leave no way of transferring a 2GB game on the N10 into the 2GB IMG file on the N10.
My second attempt was USB Sharer, which allows sharing a virtual usb drive AND mounting it. This would in theory be the solution to all my problems, but it fails to mount on the N10. I tried Paragon and StickMount. Meanwhile it connects flawlessly on my linux laptop. It is not the OTG cable, as it works with DriveDroid.
My third attempt was mounting my phone as a PTP Camera using androids built in tools. Photo's transfer insanely quick, but I can't trick it into transfering a fake ".jpg" file. MTP is useless over OTG for some reason.
My hardware
N4, 4.2.2 Stock+Root
N10, 4.2.2 Stock+Root
OTG Cable, ASUS and Samsung original USB cables
My last desperate attempt would be to start a network over USB, if I can, and transfer using FTP.
Edit 1:
I am now looking for a way to mount ISO's and create them on a third party program (not DriveDroid).

Max file size I've ever been able to transfer was 680mb. Any more and it got rejected and said there was limited storage even though I had over 5gb free.

Connect Multiple external Hard Drives ?

Hi everyone,
I was wondering if we can connect multiple external HDD. I read that the shield tv can only recognize one connected at once?
I tried with xplore to connect 2 external HDD and it doesn't show my 2 HDD , only the last one connected. :/
Am i missing something?
Thank you.

As far as I know the Shield should be able to recognize multiple external drives (they are named and tagged uniquely). For curiosity sake; Are you using the 2017 version? Rooted? Are they both attached directly to the Shield or are you using a (powered) USB hub?

Thanks for your answer !
Yes i'm using the 2017 pro version non rooted and both HDD are directly plugged into the shield (no hub) .
Do you use an other file manager to see two external drives connected at the same time? both HDDs work well with Xplore but only when one is connected.

It looks like I have to get back at my previous statement. Turns out that what I thought was general Android-practice is actually a feature of the roms I use (on other devices). On top of that I guess my own current situation is slightly different than yours; while I do have both a thumbdrive and a HDD attached I have adopted the thumbdrive, so it's not counted as an external drive. If I open Xplore I can therefore see both loaded.
Since I feel a bit like an arse I did some digging to see if there is anything you could do to hook up both drives. Turns out there's more people that have run into this here including a very descriptive solution should you have 2 identical HDD's. Otherwise, below a list of possible solutions;
If you are rooted, or willing to do so.
There is an app called "StickMount" by Chainfire which basically allows you to hook up multiple external drives and even symlink them. The catch is; I am not able to test this since myself I'm not willing to root my Shield 2017 just yet.
If you aren't rooted.
There are a few things you could do.
1] The solution I went for myself; buy one big USB 3.0 drive (I went for a 5TB one) and transfer all your stuff.
2] You could choose to adopt one of the drives as internal storage. There are some glaring downsides to this though; you can no longer attach that drive to other devices, it will at first wipe the drive and if its not a fast HDD it is going to lag your Shield down. Also, since your Pro already *is* 500GB and you would basically swap that space for one of your HDDs you'd have to consider whether or not it is worth the effort.
3] A somewhat farfetched solution; should you happen to have a modem that supports hosting a HDD as as NAS, you could use that to hook it up remotely. It's not as fast, but technically it is a solution.
