Every time i connect my wizard to my machine using the USB cable, i get the following message in baloon.
"One of the USB Devices attached to this computer has malfunctioned, and windows does not recognize it."
It appears as "Unknonw Device" on windows device manager.
This started happening when i changed my ROM to AMP.v2.Vanilla. Prior to that my wizard was connecting fine. I have been trying to resolve this for days now but no luck.
Following are the things i have tried.
1. Un-installed Activesync & re-installed.
2. Soft & Hard Reset the device.
3. Tried going in bootloader so that i can install my preivous rom, but the machine still doesnt recognize the device and gives the same message as mentioned above.
4. Removed all the USB controllers and re-installed in the machine.
5. Tried on different machines but same results, so its not machine specific.
6. Tried with a new cable to so its not the cable, it has to be the device.
Anyone who can help with this. I am sure i am not the only one having this trouble.
Any kind of help is appreciated. Just need to connect and go back to my preivous rom.
Thanks in advance.
Nick.
Please don't cross post. Pick a flavour and run with it.

My apologies mate. Its just that i am little desperate now to make this thing work.
So just recently my usb and sd card decided to malfunction. My usb will charge via my pc but it comes up on the pc (Vista 32bit) as 'Windows cannot recognise this device' my drivers are up to date. However in my device management i did notice that my 'Mobile Device's' section had gone
I also tried formatting my sd card using a card reader, but it wont format it
I want to flash a new ROM, any way of doing it without an activesync connection? i managed to get the NBH image on my sd card by using another storage card but i still couldnt establish an activesync connection.
Any help would be much appreaciated as this is driving me crazy
Thanks, Dan.

Just checking, you did update your usb drivers according to this guide?
Otherwise, do you not have access to another pc?
You can also try this solution, it helped another user earlier

Have you tried a simple thing like rebooting the pc? That sounds however more like a hardware issue on the pc or phone. What happens if you plug another usb device into the port eg a usb flash drive, does that pick up? In your device manager, are all usb devices functioning properly? Perhaps try to roll back the drivers on the ports if possible and re-install the usb driver update.

All My Other USB Devices Are Fine
I Cant Roll Back The Driver In Device Manager Because It Apparently Isnt There, But Nothing Has Been Changed, WMDC Has Been ReInstalled, Net Framework Reinstalled Etc Im Just Not Getting Any Mobile Devices Show Up.
Okay, you need someone more technical than me then bro. Sorry, but I've run out of ideas.

If you've changed usb cables, and you've checked the usb to connection setting is not on advanced, then it means the usb port & possibly main board are damaged. Did you hardspl your device?

i had the same problem here.

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.
Ok so here's the thing. This morning when I woke up I dropped my phone on the floor and the battery flew out.Initially I thought it was nothing but later it started rebooting without any good reason. I tried restarting, it would stay on for a bit then it would go down again. I am(was) running CyanogenMod 7 on a Samsung Galaxy SI. I want to reflash it with Odin as it won't start anymore.At first it would just boot loop but now it won't even get past the first logo. The tricky part is that my PC won't recognize it , all I get is Unknown Device code 43 yada yada BS! I tried alot of drivers, I tried the have disk method with the usb driver from SDK Tools , nothing worked ! Please, give me some suggestions about what I should try more because honestly this is beyond my expertise in this domain.

code 43, has more to do with Hardware, its about your cable and PC ...so check cable, try switch to another USB port
Microsoft engineers answer
I suggest that you connect the Controller to a different USB port and check if you have the same issue.
If this does not work, you can try to uninstall and reinstall the USB controller.
To remove and reinstall all USB controllers, follow these steps:
1. Click Start, type Device manager and open device manager.
2. Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove them one at a time.
3. Restart the computer, and then reinstall the USB controllers.
Disable and enable the USB device:
1. Click on start and type devmgmt.msc.
2. Right click on the caution sign on the USB.
3. Select disable and reboot the computer.
4. Enable the device after reboot.
Also make sure that you download and install the latest version of Software for this. Here is a link you can follow to download the Software:

try and borrow another original samsung USB cable to test first, this is a major culprit, as numerous people including myself have experienced
what happens is one of the pins on the micro usb plug of rolls in and gets broken , also check your USB slot a good cleaning with a brush and alcohol would be good fro the connection ( do it when you have removed battery)
Got another USB cable still nothing... It's very weird, it's like nothing I heard off or read on the forums... Is there any method of connecting to the mobile using SDK manager ? I'm not really familiar to working with the SDK manager.

was your cable an original samsung cable, IF not, many common cable do not work, due to pin configurations
For ADB, you still need connection with USB cable

I'm trying to use LG PC Suite and LG Bridge on a laptop running Windows 7 x64 Pro. I have updated the chipset with the latest driver, but every time I try to install the LG drivers, the SM Bus Controller fails to install. The PC cannot see the device, even though I have switched USB mode to file transfer. I have a Mac as well, and the same thing happens there (not recognizing the device is connected via USB). Is the software just way out of date and not yet compatible with the V20, or is there a fix that needs to happen. I'm perfectly comfortable using the command line/terminal or hacking the registry, if that's what it takes...
Thanks to anyone that can help!
I did remove the SM Bus Controller from device manager and then re-installed the LG device driver. It did not attempt to reinstall SM Bus drivers, but instead installed MTP drivers successfully. I had high hopes after that, but it's still not working. Sigh.

What are you trying to accomplish?
Have you installed minimal adb\fastboot?
Frankly, I don't use Windows or Mac so I am next to no help there.
'Sudo pkg install android-tools-adb android-tools-fastboot' was all I've needed to do.
Is your usb a known good cord? Verify this first. Then, Windows device manager, plug in your phone, watch for something to show on device manager. Click on device, double check there that everything shows as working properly?
If phone is not showing up on a number of computers, make sure USB cable is good.

I have adb and fastboot both. I want to connect to the PC/Mac for purposes of synching/sharing music, photos, etc. I could use linux too, but I don't have an VM's or a box spun up with anything atm. Yes, the cord I'm using is a good cord. I can see the internal and SD card when I connect, just can't use the LG apps. Oddly enough, there wasn't anything showing with the yellow sign under Device Manager. I'm guessing it's just a compatibility issue and I should just forget about it and just push files to my device with adb. Oh well--I thought it was worth a shot.

It's cool, thanks anyway. Just trying to simplify things. Don't ask why I thought the OEM's software was gonna solve that, lol.
Well, tbf, even though I don't use it (simply because I dislike vendor lock in - owncloud or a sftp session is mostly hardware agnostic.) I do understand the idea that one should expect the **** that come on the phone to work properly. It *should* be a selling point - 'our apps work for their stated purpose!'
