[Q] Win7x64 USB - Device Not Recognized

I tried connecting my Transformer to my PC this morning to make copying files to internal memory a bit quicker than using wifi. Assuming it would be like pretty much every other Android device, i just plugged the Transformer in using the supplied USB cable and assumed Windows would recognise the Transformer and download the appropriate device driver.
Unfortunately, it did not recognise the device and came up with that message. So i uninstalled the generic drivers for the unknown device and then installed the Asus PC suite thinking that this would work. Rebooted computer, plugged in Transformer and again same message, device not recognised.
Why isn't this simple? I'm yet to try on another PC. Can anyone suggest any tricks to get this working?

Just download the actual USB drivers from ASUS, plug in the TF, right click My Computer then click Manage, select Device Manager from the pane on the left and find the transformer in one of the dropdowns on the main pane. Right click the transformer in the dropdown and update driver, choose to find driver yourself, navigate to the ASUS usb driver folder you downloaded and continue. Drivers should then be installed.

Thanks for the suggestion. I've tried to manually install the drivers this way and pointing to the inf files to install but windows says they are not a valid driver installation file. I noticed someone else was having this problem in another thread and it was unresolved.

Weird. I have win 7 x64 on my desktop and laptop and never had problems installing drivers or recognition problems. Should try connecting to another machine with x64, might be a hardware problem with your machine.

If you run the asus sync or pcsuite application, either one will install automatically the usb drivers.

Remove all the drivers you have installed and then reinstall from ASUS. They may be conflicting

[Q] Tf101 and win7

Hi everybody!
I write here `cause I have a problem qith my tf101 and my pc (win 7) connection.
I used to be able, with the proprietary cable, to connect the two machine and manage the files in the tf101 as an hdd (even windows saw it as a different device, not hdd).
Recently I try again and.. nothing. Even with other pc, no sucess. the tf101 is not recognized at all (after a one-time attempt to install the ""unknown usb device"). The only things that I`ve done are the updates to the tf101 when avaiable. The version of the kernel is now 2.6.36.3.
I`m looking for a solution in the net for sometime now, and the only answer I get is the suggestion to connect via samba or similar. I`ve tried but is not intuitive and fast as the cable connection I use to use.
Has somebody solved the same problem or has any suggestion to make the cable connection work?
ps: I`ve already installed the latest drivers from Asus website in the pc.
Thanks in advance!!

1. try other PC or another OS on your PC
2. try other Cable
3. check your privileges on OS
4. etc to exclude negative staffs 1 by 1

I`ve already tryed with athor 2 pc (one win xp, one win 7), and another cable.
Still have to try with Ubuntu. I`ll do it as soon as I can.
As for the privileges.. you mean in the pc? Over there I`m admin. In the tf101... I didn`t do anything so I`m not superuser, if you mean that.
It seem strange that I used to be able to browse the tablet from the pc and all of a sudden I can`t anymore.

Tryed with Ubuntu. Doesn`t see it as well.

Win7 Will Not Connect To Xoom

I just got a new Win7 Pc and now when I try to connect my Xoom to it it says Unknown MPT device. I tried installing the drivers to no avail. I didnt have this problem on XP. I am running stock ICS on my WiFi Xoom. Any ideas?

Where did you get these drivers from? Try the ones directly from Motorola.

You could drive removing the current drivers and SW. Try just using the device then runnign the moto install for those drivers. Make sure USB is enabled correctly on the tablet too. Is it charging from the usb connection? You could try a different port it shoudl charge regardless.

Xoom doesn't charge via USB..

I am using the drivers and software directly from Motorola. I have tried it with USB debugging on and off. I have tried switching it from MTP to PTP on the Xoom and still the same results.

Go into device manager and see what's up. Make sure xoom is plugged in beforehand. Right-click My Computer -> Manage -> Device Manager.
If there are no errors (!) to do with the xoom, then some form of driver is installed. Manually delete these by right-clicking on them.
Then take out xoom, and put it back in. Win7 should automatically find the MTP drivers.

I'm getting the same exact problem and I've gone through uninstalling windows media 12 to acquire the mtp drivers and nothing, i can't even get it to install wmp11.grrrrrrrrrrrrr

does the xoom show up in Windows Explorer under "Computer"?

ADB Does Not See TF700

I cannot for the life of me get ADB to recognize my new TF700. I've tried using the naked drivers, along with the ones Windows installs by default.
Android SDK is up to date.
I've searched every thread high and low and cannot figure this out.
I didn't have nearly this much trouble with my TF101.
I'm at my wits end, so any help is appreciated.
TF700 is new out of the box, with Android 4.1.1

USB debugging is ticked in settings right.
Look in windows device manager see if it shows as USB mass storage device.
If not remove usb from the PC then plug into a different port on the PC.
Also sometimes the sync software from Asus will force Windows to recognize the tablet.
Is there a micro card in the tablet?
If so unplug the tab remove the card after unmounting then plug the tab back into the usb and see if it shows up.

USB Debugging is checked.
Device manager shows "ASUS Transformer Pad TF700T" and "ASUS Android Composite ADB Interface"
I'm about to try the Asus Sync trick.
No MicroSD card is in the tablet. Should I try putting one in?
EDIT:
No difference with MicroSD card
No difference after installing ASUS Sync

Yes try the microSD card...
Can you uninstall the Composite ADB Interface and reboot the PC then connect the tab again?
Edit:
Are you on a Windows 7 desktop?
Just in case drivers for Asus tabs
ADB

ADB and fastboot wouldn't pick up mine, either, but I got it working by using another USB port on my box. Even using a simple extension cable meant that I'd lose connectivity, so make sure you plug it in directly, too.

Uninstalled Composite ADB Interface, rebooted, connected tab and used the drivers you provided.
Still no luck.
Yes, Windows 7 64-bit desktop.

I've tried multiple USB ports, even 3.0 ports, all with no avail. No extensions or hubs being used, plugging directing into motherboard.
EDIT:
Again, it's on Android 4.1.1, is this the issue?
Build Number is 10.4.4.23
EDIT 2:
Downgraded to Android 4.0.3, Build 9.4.5.30
Was able to root using kangaroot on my MacBook Pro
Still no luck with Windows 7 though

Windows can be stubborn as far as this.
Asus PC Suite may be able to overwrite the problem driver.
Glad to see the MAC came thru though :good:

[Solved] USB suddenly stopped working

I have a Nexus 5 that I have had about a month now and I had the USB on it working before about a week ago. I plugged it in today and neither my desktop or laptop could recognize it anymore. Both computers are running Windows 8.1.1 and the issues seems to be new as I can neither get USB storage or ADB to find it. The closest I can get it to working is to switch the USB mode to PTP and it reads that but I don't want to pull photos off. When I have it in MTP, it makes the sound of it plugging in and my phone shows it is plugged into a computer but Explorer shows nothing and it says it is working normally in device manager. I've tried everything from enabling and disabling debugging, restarted both my phone and computer tried reinstalling the drivers (both by the computer automatically finding them and manually installing them) but nothing seems to work. Is it possible that Windows Update could of broke the drivers since my computer installed updates yesterday? I also have Linux on my laptop and it appears to read fine with Linux.

That's the exact issue. If you check in Device Manager you'll see it listed as 'ACER ADB Device' (or something like that). You have right-click on it, select update driver, manually check and go through the list option and choose the MTP driver and it'll work again (and with USB Debugging enabled if you don't usually have it on like me)
I theorise that it's happened cause the Acer driver is digitally signed and the Google ones aren't but I could be wrong. Either way, it's a PITA

OK thanks. I'll give it a try because it was showing up as ACER ADB Device under device manager
EDIT: I updated the drivers and used the USB composit drivers instead and it got MTP working again. When I set it to USB composit, it installed Google's ADB drivers and the Nexus 5's USB drivers so everything is working again. Thanks for your help

I can´t manually update driver because of this:

when i update the acer adb it says the driver is up to date and everything is all same. what to do?

Thanks! Thought I was going to go crazy. Worked for me...

i set the driver to MTP as mentioned above and the phone started to show up on the explorer but now i couldnt copy any files from my laptop to the
phone. It displays like that and if clicked yes then the copy wouldnt happen.what is the problem.

Uninstall driver, plug in device, tell windows to not auto install driver (or disconnect from internet), click to update or install driver, point to folder with drivers, install, all is done.

That msg comes when you're in PTP mode I think...Only certain formats are supported.
Check under storage, expansion menu and make sure you are set to the first option...not PTP.
Above guy mentioned to have phone in USB debugging mode when setting up drivers.

If the device is showing then you need to point to the drivers for it (download them from google). I reinstalled windows a few days ago and had the acer issue (device first shows up in device manager as nexus 5 then switches to acer), windows wants it to be an acer device. Stop windows and then install the correct drivers,
For me I had to click the auto install in windows tray and tell it to stop. After a few times it worked.

No I'm connecting in MTP mode. Ahh its gettn irritating.
