You have a MkII. Same as mine. Btw, mine overclocks to 280, stable, but hangs at 290.
The USB problem is pretty common, try looking around;

Ive found the easiest way to get stuff onto the GP2X is to use a SD reader on the PC instead of the supplied USB cable, readers are dirt cheap and you dont need the GP2X switched on while moving big files.
Amiga emulation is still patchy, some things run fine with the GP2X at ~250Mhz, some things are very glitchy, but its early days yet. And there's something magical about seeing the WB1.3 boot screen on a handheld!
I'm really impressed with the GP2X, the number of free apps and the quality of the machine and the software is surprising.
The potential for exploration and tweakage is unlimited.
