When I run adb devices from my Windows XP machine there is nothing listed. The tablet's Vendor ID is 18D1 and the Product ID is DEED. It gets enumerated as a USB device with a name MID. When I enable "USB storage" on the tablet, I can see the tablet's files in the Windows File Explorer as drive G: and the SD card on the tablet as drive H: -- however the Computer Management shows a big yellow question mark next to a device named "MID".

I searched for a suitable driver but all I could find was a list of drivers for well known brands. My tablet is a no-name version of the Hyundai A7 Art.

I've been struggling with this for quite a few days. My purpose is to collect a logcat to document another problem that I posted here. I hope you can help me out.

Have you enabled USB debugging on the device? (Settings -> Developer options -> USB debugging) – onik Apr 4 '13 at 13:27
Yes, it's enabled. – alexb Apr 4 '13 at 13:29
I have also tried to connect with >adb connect and I got the message unable to connect to even though I get replies to ping – alexb Apr 4 '13 at 13:34
Do you have the correct device drivers installed? This may sound odd, but you can you try installing PDANet which includes drivers for a lot of devices (although your tablet may not be common enough) You can uninstall it after you have the correct drivers. – Bryan Denny Apr 4 '13 at 14:07
Thank you Bryan. I was just about to post about my success after installing PDANet, when I came to this page and found your message mentioning it :-) I am glad you told me I can now uninstall it, as I was not clear what the main purpose of that software is. – alexb Apr 4 '13 at 15:02

Try to re-install the USB device driver for that specific tab, and try it once again.

That was exactly the problem: I didn't have a device driver to install. Anyway, I just solved it with PDANet (see above). Now I can move on and debug why I cannot login to the Google Play Store – alexb Apr 4 '13 at 15:06
