I'm running OTA 4.0.3 (Acer_AV041_A500_1.033.00_PA_CUS1) rooted with I don't know what tool, but rooted after upgrading to 4.0.3, and using one of the tools found here which was the latest (at the time of rooting). The tablet has an "A500 Root Tools" app which has options to enter APX mode amongst other things.
I'm unable to get my Acer to connect to my PC via USB. I tried using both a mini(?)-usb cable and an A-A cable. My acer makes no notification, and there's no visible, or audible, evidence that anything was connected. USB Debugging enabled and disabled makes no difference. The tablet shows absolutely no sign that anything was plugged in. Nothing in notifications, nothing in any file managers.
Likewise on both a Windows 7 PC, and a Windows Vista machine. No little sound saying I plugged something in. Nothing listed in device manager. Nothing anywhere. The Win7 machine has the Acer drivers installed, as it is the machine I used to root it a few months ago.
Is there some weird ICS toggle that I need to perform to get this working? I know my USB ports are working as I've plugged in USB sticks and it mounts them without issue.
At the end of the day, I'm just wanting to flash my bootloader so that I can install CWM and a custom ROM. If there's a way to do that without needing my PC connected, that would make me equally happy.

Reinstall the Acer Drivers and also the Google drivers from the android sdk if u have that installed, if not use the adb_fast.zip attached. For you to successfully flash the BL do not underestimate the importance of having the drivers correctly installed - its the cause of 90% of the problems folks have had - my advice is to keep Device Manager open the whole time so you can see what is or isn't installing - dont proceed with the flash until you are sure they are - else you'll be looking at a downgrade to HC to fix things
you can also use Acer Recovery Installer from the market to install a custom recovery
While I appreciate your help, my issue is not drivers - Windows isn't loading the wrong drivers, or no drivers at all. Windows is showing no sign at all, at all, in device manger, any where, that a tablet has been plugged in. Like wise, the tablet gives ZERO notifications on being plugged in to a PC. Nothing. No sounds. No notification. Nothing.
I was originally using the micro(?) usb slot, and it was not working. I assumed that USB slot was dead. So I went and bought a USB A-A cable - after testing the normal USB slot and established it works - and it, too, does absolutely nothing when plugging the device into a PC.
I've since tested with an Ubuntu 12.04 machine as well. dmesg lists nothing.

and the adb interface driver thats not showing in device manager?? and you have the acer drivers installed??
All the signs are pointing to no drivers, failing that its sounding like a hardware issue either yr tab or cable - can u try on another pc/laptop?
Tested it on a Win 7 Dell, on a Vista Dell, and on an Ubuntu 12.04 Compaq. None show any sign of the device being connected.
I know my *two* micro USB cords work as my Nooks (color and tablet) have no problem with them. I know the large USB slot works as I've plugged in a keyboard and a USB memory stick and both are immediately detected by android.
I've also done a factory reset on the tab. Problem persists, obviously.
I'm actually setting up stock Win7 on another laptop right now. When it's complete I'll install acer drivers and plug in the tablet. It will be the only USB device, let alone android, to ever be plugged in to it.

The tool you used to root it (icsRoot) also has an unroot tool, which you could have used...I have tried to unroot manually which wasnt easy as I had a pre-rooted rom and I had real trouble getting rid of superuser, but in your case it may be a bit different....Sorry can't give you much help in the unrooting ics dept. Maybe try flashing acer stock rom??? or starting a new thread??

are you trying to flash something or do you mean when you connect yr tab
windowz explorer doesnt show your int/ext storage??
more info needed, what rom and bootloader, what OS on yr pc can u try on a different one, try a different cable and usb port..
have you run the acer drivers setup.exe
did u install the android usb ones
have u opened a command prompt from the folder where adb.exe is and run "adb devices"...does a number show??
when u have device manager open and connect yr cable do you see the drivers install. If they are there then uninstall them, disconnect yr cable and clean boot and reconnect.
If they do not install then manually install by pointing them to the folder you extracted the zip to...for the acer ones, just point it to your c: drive
If windows trys to install them, stop the hardware wizard from searching windows update and manually install them yourself.
If you've tried to flash the bootloader and it hasnt completed for what ever reason - you can strike issues such as yours - again, uninstall, clean boot, reconnect, manual install

That's correct, a straight USB "A to A" won't work. Further, I discovered something else; not all micro-usb cables are created equally! I was using a cable that worked fine on my Thunderbolt phone, would not work at all on my A500. Turned out there's some enhancements to the pinouts on the newer micro-usb devices. So the lesson here is go with the cable that came with the device if at all possible.
Seriously though, give a different micro-usb cable a shot; they're pretty cheap around the interwebz.
While my original NC is running quite well with the CM10 nightlies, I have lost my ability to use the USB cable as my file transfer source since leaving CM 7.2.
I now do all of my files transfers directly to the SD card by removing it and accessing it directly via my computer.
I get the following when the cable is connected: "USB device not recognized".
I have tried both Media Device and Mass Storage settings to no avail.
This was not an issue with CM 7.2.
Seems to be the only real issue I am experiencing since I was able, with forum help, to redo my inadvertently updated NetFlicks.
Thanks in advance for any suggestions.

First, don't call the ROM JZ054K, it is CM10. You confuse folks. The problem probably is you have USB debugging enabled. Go to settings, developer options and uncheck Android debugging.

Followed your suggestion and unchecked Android Debugging. Rebooted and then hooked up the USB/Recharge cable. Still have same result with the "USB device not recognized" being displayed by Win7/64 with both Media Device or Mass Storage being selected.
Any other paths to explore on this?
Utilized my ROM nomenclature based on "About tablet: Bulid Number" and will switch to CM10 if that is a confusing issue.

The device id and vendor id are different in the CM10 from CM7, you would need to edit the android_winusb.inf file to include them.

Are you sure it is still unchecked? Did you go back and look after rebooting. You should not have to reboot to turn it off. That device not recognized issue is it is looking for ADB drivers because the debugging box is checked.

Yes, went back and looked and it was still unchecked. Normally reboot when I make any changes but went back and redid your suggestion from scratch without rebooting with same result.

The only thing I can think of is to go device manager in Windows and uninstall any devices in portable devices, android phone and under USB controllers, any mass storage devices. Then unplug and replug it back in, assuring debugging is still of. You should now get messages that things are installing, hopefully automatically.

I'm having the same issue, was using the Dec 2 and now 3 nightly. when I get time tonight I will roll back to Dec 1 since I know it was working there. Win7/Win8 here fyi
Unsuccessful
Tried: "...and under USB controllers, any mass storage devices." This actually allowed WE to show "Nook Color" but when I clicked on it, there was nothing there. The unit did temporarily display a USB connection at that time also.
Again, this was not an issue under CM7.2.
Thanks for your ongoing assist!
Update: Okay tried every conceivable way of deleting some or all of USB drivers under DM and reinstalling. Even went into BIOS and turned down USB 3.0 to 2.0!
Again erratically got the Andoid USB screen temporarily a couple of times but could not maintain it.
Definitely getting a Windows "Code 43" error indicator.

If you are getting windows errors installing drivers you may want to look at this post. It is for the HD+ and trying to get ADB working, but there is some interesting stuff there about unsigned windows drivers that may apply to you.

It was very frustrating seeing the Android USB screen fleetingly appear several times and not be able to nail it down. I even got the WE screens for both drives briefly at one point!
Any idea as to why the issue exists with CM10 and not CM7.2?

Went there (http://forum.xda-developers.com/showthread.php?p=34954992) ...did that. Did not work at first, but it did work (somewhat) after I went back in and deleted the three drivers. I was then able to connect and utlilize WE to probe and adjust both emmc and sdcard. Calibre recognized that it was connected but I could not transfer anything directly from it to the NC.
Thanks for all of the help with this. Since I am probably around eight weeks from purchasing my HD+, I will just use the SD card to manually transfer files.
Interesting issue nonetheless!

I plugged my nook into a couple different computers and it was like the computer didnt even recognize something was plugged into the computer, though it charged the nook fine.
Had same problem, I went to settings - storage - then the menu box top right (three dots) then choose USB computer connections.. For the most of the time I just leave mine on Mass Storage -- On the second - I just leave the stock file manager and install any others I use - stock is not a lot of overhead for me to bother removing...

Hi,
Just got a Nexus 4, had a Galaxy S2 before. The problem is that I can't get it to be recognized in Windows 7 x64. Nothing really happens, I plug it, it starts to charge but nothing more, no icon appearing at device manager etc. Tried to install the drivers via nexus 4 toolkit and nothing changed, tried on another windows 7, a notebook and its the same. Changed the USB cable, no difference. Charging and nothing more.
I searched on internet and found similar issues but didn't find a solutions.
PS: Its a new phone, never unlocked or rooted.
Works here dude download latest android SDK and go to device manger on computer update drivers

Installed the toolkit, folowed the instructions but the problem still there. The problem is that when I connect the phone I don't get the "connect to usb" familiar sound but the charging starts. So is not that the drivers are wrong or bad, the problem is that is that the phone doesn't even shows as something in device manager.
Go to your phone settings.... then click on about phone....
then scroll down and hit the "build number 10 times" that will unlock the developer menu
then go back to "about phone" scroll down to the developer menu.
then check box for "usb debugging" and the computer will see the phone.
Had this problem too the first time i got my Nexus 4.
It frustrated me for the first couple of hours when i could'nt connect it to my pc, and no solution seems to work.
However, i found the solution. This was: Install the latest version of Windows Media Player.
This phone uses MTP, instead of mass storage, and thus needs WMP.

I have this same problem and haven't found a solution yet!
I have this problem only when USB Debugging isn't turned on. I'm not sure what's wrong with it but by computer (running W8 Pro) won't see my phone until I turn on debugging. All drivers are installed but the only way I can copy files to/from my N4 is with debugging enabled.
Would love to see a solution come through and I'll continue looking for one myself to help us all out.
-Sent from that.... you know.... thing that sends these things-
Same issue.
I have tried over 5 computers running windows 7 and about 5 different usb cables.
I have tried having usb debugging checked, unchecked, MTP on/off and PTP on/off.
Still nothing.
Im having this problem too. I tried in 4 different pc's and a mac. My nexus 4 cant be detected. Its just charging. Weird thing is that no "Charging (USB)" on my lock screen just "Charging"
i had the same problem and read everysingle forum and finally found the working solution
Device Manager - right click device (Android ADB OR Nexus 4 ADB interface)
- Update Driver Software
- Browse my computer for driver software
- Let me pick from a list of device drivers on my computer
- then choose "MTP USB Device" OR "USB composite driver"
- Next
here you go instant discovery
make sure you are on MTP and USB debugging is on

What OS are you using? Windows? Mac? A linux distro?
Also, are you sure you're using MTP instead of PTP (Settings > Storage > menu > Usb Computer Connection) ?
You can try to install google's drivers from the android sdk as well.

I know this is a silly thing to ask, but have you tried rebooting your phone? Something like this happened to me before and a reboot fixed it.
Also, if you have a custom kernel, check that you have USB fast charge disabled. And after that fails, try installing google's drivers. Sorry, I'm just spouting out random ideas at this point.

Use trickster mod and go to the Kernel Specific page. If fast charge is ticked off, there's not much we can do from there.

Also, have you tried to install google's drivers or make a nandroid and reflash a clean rom?

So I tried installing the newest Franco kernel Milestone (3), and the USB fast charge is off. I also tried installing a different CM mod, but there is no difference. I also tried installing the universal you gave me, but that didn't work, and i installed the google driver from SDK and that didn't work.
I don't know what else to do...
Hi, try to completly unninstall ALL drivers for nexus, samsung or android related, than install official drivers for nexus 4 and then connect nexus 4. Should work.

I tried that, no luck...I don't know what else to do, I have tried 3 different cables. I tried using the drivers that come with the nexus 4 toolkit, but no luck. It charges when plugged in, but i get nothing else. Also it seems like half the time its not even in the device manager as an unrecognized device, and then it intermittently pops up a window saying unrecognized device detected... maybe my USB port is broken on the phone?
Is there something simple I have overlooked to get 4.2.2 to work with my computer?

Have you managed to solve this? I'm facing almost the same problem!
No, I tried for hours with no luck. I am glad I am not the only one, hopefully a solution will come to us. I have been using airdroid to transfer files from my phone in the mean time.
Im also having the same issue except my computer only recognizes my phone when its connected as a camera.

I am having a similar problem with my daughter's Nexus 4 phone, which is not rooted nor unlocked - it is still completely stock. It was just updated to Android 4.3, however I can't say that this is the cause of the problem because she never attempted to connect her phone to the desktop machine before.
I have a Windows 7 x64 box at home, and spent over two hours last night trying to get the computer to correctly recognize the Nexus 4 phone. I was hoping that the standard MTP Windows driver would handle it perfectly, but no luck. I tried the Google usb drivers, and the ADB interface was recognized, but still no access to the internal storage. I then gave the Naked Drivers a try, and no joy there either.
I am beginning to suspect that the MTP drivers on my desktop are munged, but do not relish the thought of a Win 7 wipe and reinstall.
Anyone else have any ideas?
Thanks much!
I am having a similar problem where I have USB storage set to MTP and Windows doesn't pick it up, whereas PTP Windows will pick up but I can't access any folders other than the camera related folders like DCIM.
So my workaround is doing it the old fashioned way through CMD in windows using adb push.
Example:
Assuming you have all the stuff you want to transfer in a folder called stuff, adb is located in C:\adb, and your folder known as stuff is also in C:\adb:
C:\adb>adb push stuff /data/media/0
The above command starting from the ">" will transfer all files in the folder called stuff to the root of /sdcard. In the N4, /sdcard is symbolically linked to /data/media/0.
Of course you need USB debugging enabled for this to work...
Device Manager (Hopefully this helps)
In the start menu type device manager, in that window you should see android and or something similar at the top. You want to drop the menu down and right click what should say Google ADB Interface and delete it, make sure you check the confirmation box. After reboot your computer! Once booted plug your phone in a viola!!!
I'm having a similar issue.
I can open device manager but there in no Android anything listed. All that comes up when I plug my phone in is 'unrecognized usb device'. I have 5 different cable I have tired. The OS will only bring up the usb error in a USB 3.0 port. It will not do anything if I use the 2.0 port.
I have gone and tried to manually update the drivers through the device manager but when I select the drivers from Android SKD or any of the other driver packs I get an error that it is not a x64 driver.
I found one suggestion about modding the driver to include the device but windows will not even recognize the device other than a unknown usb.
I'm going to have a bricked computer soon. Any help would be appreciated.

First, Google universal naked drivers xda. Try those. If they don't work go into device manager and go to where it says let me choose drivers from my computer. Then look for the android composite adb interface.
If you're on win 8 you'll need to allow unsigned drivers. Google how to do that

Windows 7x64 on all machines. I am trying this on 2 work computers and getting the same result. I have 2 issues that I think are the root of the issue.
#1 is the phone doesn't do anything in USB debug mode. I keep seeing references to having to approve the computer connection but I haven't seen that yet. I have tired 9 usb ports. 6 on my main computer will not bring anything, not even the usb drive. 3 on the labtop will only bring up a 'unrecognized usb drive'.
#2 is the computer will not recognize the device in anything other than a 'unrecognized usb drive' (UUD). Everyone keeps mentioning the Android Composite ADB interface. It's not there, it doesn't show up or as an option. I can go into the device manager and find the UUD and try and update the driver via the manual method with a disk but it doesn't list any type of hardware that is related to Android or ADB.

Hello,
"#1 is the phone doesn't do anything in USB debug mode." This is normal!
How I experienced the USB debugging option is that, if turned ON:
1. The Nexus does not appear in my Windows env
2. BUT when in recovery mode, I can use the "adb" commands
If USB debugging turned OFF:
1. Then I CAN see the Nexus in my Windows env
2. BUT I cannot use the "adb" commands in recovery mode.
So you definitely need to have the USB debugging option turned off if you want to see your nexus in Windows, IMO

I think you really have an issue with the drivers. I would install the Google USB drivers. Maybe a bit heavy but then you can be sure that drivers are fine:

Hello guys!
I have already read some topics on this forum but it is my first message.
As indicated in the title, I cannot connect my Nexus 4 on my computer using MTP. This computer is running Windows 8.1 Update 1. So far I have tried every method I have seen on the web so I am a little bit desperate.
I have tried to plug my device on other computers and it was automatically detected on Windows 7, Windows 8.1 Update 1 and Ubuntu 14.04.
On my computer, as it does not auto-configure MTP I have tried to install ADB drivers, hoping it would help me. Universal ADB drivers, Naked Drivers and drivers from the SDK didn't changed anything. I also tried changing USB port.
It always recognised my phone as a "Nexus 4" in the "Other devices" section of the Device Manager (I do not have "Android Device" section), except in when MTP + debugging are activated. Then I have both "Nexus 4" and "MTP", in "Other devices" section.
It does not work in PTP mode either and I also tried uninstalling/reinstalling the Nexus Root Toolkit, even if I do not see how it can help...
One last point: I have the "connected as multimedia device" notification on my Nexus 4 when MTP is activated, even if it's not recognised by Windows.
Do you have any idea of what I can do?
Have you tried Nexus 4-specific drivers? Try following this guide.

I have already tried to follow this guide, it just helped me to install ADB drivers but I still don't have access to the content of my Nexus from my computer. I just tried it again, just in case. No changes

Last time I had such an issue: I uninstalled the drivers using Device Manager, then installed the drivers from that guide, plugged in my phone and it worked..
Here is another post from another forum that has something you could try:

1. make sure Settings ->Storage -> Menu[3 dots on top right] -> USB Computer Connection is MTP
2. USB debugging is disabled (if you ever enabled it)
3. make sure the drivers installed is MTP drivers rather than adb device(you do this when you unlock/root nexus)
point 3 is important. thats the reason why its not getting detected

2. Where in setting do I check for USB debugging?
3. How do I check this? (I'm not rooted)
Click to expand...
Click to collapse
2. developer option.. if you have not enabled developer option then you wouldnt have enabled USB debugging. so skip this
3. Connect your nexus to PC-->Go to Control panel-->device manager
you will see something like Android adb in device manager
Right Click and click "Update device Software"
Click "Browse your Computer for driver Software"
Click "Let me Pick from a list of device drivers on my Computer"
Click Next, for the device list shown.

Yes, I saw it worked for a lot of people, for what I have read, but it seems that I am not that lucky
When picking from the list, I tried from the Android Device section and it displays "Unable to find any drivers for this device". Same Results in “Mobile devices”.
When I try “Show all devices”, I have a lot of possibilities. I just tried “MTP Device” from both “Standard MTP-Compliant Device” and “Standard MTP-Compliant devices” sections, and it displayed “The install class is not present or is invalid”
Am I cursed?
I was wondering, is it possible that the problem is coming from my hardware? Or its drivers? (Those for the motherboard maybe?)
EDIT: I just found this thread : http://forum.xda-developers.com/showthread.php?t=2493734
I will try it and I will keep you updated when it is done.
EDIT 2:
So I tried the solution... and it worked! :good:
I had the N version of Windows 8.1, mainly to avoid useless software like Windows Media Player, and it was the exact problem.
Sorry for taking a little of your time, and thank you again!
No problems, I'm glad you had it fixed.
