I've been having consistent issues connecting with the tablet through adb, on both linux (2 separate installs), and windows 8.1. Sometimes it just will not detect it. It gets detected as mtp storage fine, but adb devices returns nothing. Ill triple check all the relevant settings, make sure the computer has been authorized by the tablet etc. It will literally work just fine, and then 10 minutes later without even disconnecting the cable to using the tablet, it will no longer be detectable by adb.
I'm hoping it's just bugs in the release firmware that haven't been ironed out yet, and will disappear with future upgrades or with the flashing of a custom rom.
I've also had it refuse to charge through my laptops USB ports, even the special "faster charging" port.
