I bought an ASUS Memopad HD7 around the 10th of November 2013, mainly to check out an app I'm writing on a newer version of Android. I was able to debug my app until around the 20th of December. Then adb quit working. Typing "adb devices", from the command prompt, shows a blank list. Device manager shows ME173X under portable devices, with no problems indicated. Under ASUS android devices it shows an error. If I attempt to install the driver, an error occurs. The error message indicates that adb could not see the tablet, so the driver was not installed Everything works just fine with my HTC Mytouch phone. Yes USB debugging is enabled, and worked at one time. The tablet displays a message saying that USB debugging is connected, when it is connected to the PC. This problem also occurs on my laptop. I am able to transfer files through windows explorer.
I have tried the following:
kill then start the adb sever.
re-booted the computer, laptop, phone and tablet.
tried connecting as charge only, MTP, PTP, and built-in-CD-ROM.
updated the SDK.
un-installed and re-installed the drivers from ASUS.
Thinking that an app I installed on the tablet is the cause, I un-installed it.
I did a factory reset on the tablet.
I isolated my computer from the internet and temporarily disabled my virus protection and firewall.
I also obtained another version of the drivers from ASUS support.
When an attempt is made to install the drivers, I get an error indicating the device is not visible to adb.
None of these fixed the problem.
Here are the details of my devices:
Desktop computer:
Lenova Vista PC
Intel Pentium dual CPU E2220 2.4 GHz
3G RAM 32 bit
Windows home premium service pack 1
adb version 1.0.31
