[Arm-netbook] tablet casework prototype done

[Christopher Havel]

Cracked it open, out of curiosity. It's a Micronas UAC-3556B. Probably
counterfeit, given the SimSun style font on the chip. LOL.

I can send you photos if it would help somehow, but it's definitely not
what you're looking for.

The Plantronics dongle is a "USB DSP v2", for the record.
