I have a Tablet running Android 4.0.3. Its DOMO x3g, works fine except that when I connect an external usb keyboard to it,it doesn't show up any recognition or anything.While USB pen drives, hard drives easily work on the tab... Any solutions?
Yes, I had the same issue, it never worked for any PC USB Keyboards, except the one which we bought from DOMO, that nCase K6. That K6 worked perfectly (even to my PC). But a PC USB mouse worked on my DOMO Slate X3G. Buy a nCase K6 or, preferably you could install USB Host Controller from Play Store, as said by the first answer.. That should fix your issues.
Install USB Host Controller from Google Play, and run it.
