Thanks for such a thorough reply! Things are starting to look up. But first to answer your questions... The trimmer is/was fully clockwise. My tablet never got a charging indicator. My phone did get a charging indicator, but it was weird - it would sort of flash the charging indicator on and off. Perhaps that's an indication that the wall wart can't deliver enough current (there were no labels on the wart indicating capabilities, but it isn't petite (an old battery charger)).
The PC did recognize the device and I was able to install the drivers and query the IOIO with IOIODude. The results: Hardware version: SPRK0020 Bootloader version: IOIO0400 Application version: IOIO0330 So I guess it is working as expected. I just need to up my game. I'm off to solder on the headers so I can safely short the boot pin and flash this firmware... Thanks again for your help.
