[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

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"?

[Q] Windows 8.1

Hey Guys,
I cant seem to be able to access the N5 as a media device on windows 8.1.. just wondering if anyone got it working?
I've tried searching around and tried a few things like trying to download MTP drivers from Nexus 7 but nothing seems to work.

Same for me.. Windows 7 here.

works fine on 8.1 here

Oddly enough, I have no issues on my Windows 8.1 Desktop but on my 8.1 laptop, it doesn't work at all. Both we're upgraded from 8.0, no fresh install. Both worked before. Obviously something more to it than just Windows 8.1

It shows "Google Nexus ADB Interface" even when I disabled USB Debugging.

This is the driver I installed on my Win 8.1 machine and also a Win XP machine. Both work for adb/fastboot and for storage access.

PC says it's the same like I have installed.

Plug the Nexus 5 into your computer with the USB cable.
Open Device Manager.
Find "Android Device" near the top and expand the node. Double click on "Android Composite ADB Interface".
In the properties window that pops up, uninstall and delete the current driver.
Unplug your Nexus 5 and plug it back in.

Try putting your phone back to usb debug mode and then from device manager uninstall the Google Nexus ADB Interface. Then at the top under actions click scan for hardware changes and try to install the driver again when it finds the device. I know i had to do this on mine.

Thanks, it helped halfways. It can't find drivers for Nexus 5 and MTP.
EDIT: Deactivated USB-Debugging and it worked! Thanks!

I´m looking for mass storage mode.
All I was able to do was to get working ADB mode and MTP mode. Totally easy....but whatever I do....no mass storage mode?!

Where did you read that? Google suppressed the mass storage mode with jb, since 'internal sdcard' is merely a folder of data partition mounted as a virtual vfat disk through fuse.
I can't imagine they suppressed a feature from android filesystem setup to introduce it back on a single flagship device.
And even if I'm not dev, every dev questioned about this said it's impossible with this filesystem setup. It would be only possible with a separate partition, (like on my sgs3) with external sdcard for example.

i have an original 8.1 and an win8 upgraded to 8.1...
i cant install it on both machines
tried with usb debugging on and off. i can see the device, but i cant install it. only adb drivers. but i want to use USB storage (MTP)
kinda embarassing: good old windows xp, running on a 10+ year old laptop performs perfectly fine-.-

Thanks for the help.. got the ADB installed but when in debugg mode MTP comes up but wont install drivers for it.. when debug is off MTP doesnt sho in device manager.. i just want to get MTP working

A700 USB problem

Hello.
I've got A700 and I'm trying to root it but I've got a problem. I tried it with every key combination (power, volume up & down) I found on the internet but they don't work.
I also tried it when using the USB port but my PC and my laptop won't recognise the tablet. I've downloaded the drivers from Acer but when I install them my PC asks to install NET frameworks 2.0.5727. This version is no longer available but Frameworks 3 also worked according to Microsoft. After this installation the drivers from Acer still don't want to install. Then I tried it with Android USB driver but the same problem keeps coming back.
When I plug the tablet on my PC and look in the windows device manager there is a yellow triangle on the USB port with an error code 43. I've got the same problem and errors on my laptop. They both work on Windows 8.1. The tablet doesn't appear in the device list on my pc .
Could it be that the problem is on my tablet's USB? There is no problem when charging.
Does anyone have a similar problem or maybe a solution?

Well, Win8 can sometimes give issues. I might suggest 2 things,
1) Try a different USB port. Typically devices come with USB 3 and USB 2 ports. If you have a standalone PC (desktop) don't use the USB port in the front. Try it from the back port.
2) Try manually installing the drivers. In device manager, select "install from disk" and manually select the driver (even if windows won't guarantee compatibility)
As with .net, just install the newest.
If the above don't work, well, try somebody's Win7 pc.
One more thing, when you install the drivers, make sure you "right mouse click" and install as administrator.

Chances are it is a driver issue with the computer. Does it appear on another computer with the same cable?
Uninstall old drivers and then re-install the Nexus 5 drivers https://dl-ssl.google.com//android/repository/latest_usb_driver_windows.zip

doesnt appear on any other computer

Go to "Settings", then "Storage". Click on menu in the upper right side of the screen, the three small squares, and “USB Computer Connection” drop down should show. If it does then change to PTP and see if the computer can see it.
If you don't get the "USB Computer Connection" drop down then its probably the USB drivers OR the cable!
I'd uninstall drivers from the computer by connecting phone to the computer right clicking on computer icon, choose manage, device manager, under usb you should see nexus 5 or unknown(with a yellow triangle). Right click and uninstall. Reboot computer and install the drivers listed on googles website for the nexus 5. You may have to just connect you device to the computer and let it try to install then right click Nexus 5 or Unknown again and choose update drivers and browse to the unzipped downloaded usb drivers.
If that doesn't work then i'd buy a replacement usb cable. I got so many of these laying around did you try this yet?
Are you running stock or a rom? Might be something with a rom. I remember having a similar issue several years ago with this, i'm pretty sure it was a driver issue, possibly a rom. Heck the micro usb connection on your phone could be full of dust and junk and isn't making a connection.

This has proven to work when usb drivers aren't working in recovery! Just thought i'd pass this your way in case it helps.

I can see “USB Computer Connection”, changing to PTP doesn't help.
Tried 4 different cables and 3 different laptops, no luck
Running stock ROM installed from Nexus Root Toolkit
In fastboot mode, device manager shows "Android Device" > Google Nexus 4 BootLoader Interface".
Any suggestions on what to do next?

1-install lg drivers and also update to twrp 2.8.2
2-take a complete backup of your phone and try some other rom instead of one you are using
3-also update your windows too
4-full wipe your internal partition before installing new rom
5-try some other kernel
