Well, the USB gadget comments by me were pretty much just comment. USB Gadgets are supposed to be either loadable module, compiled in, or removed. Problem is, there is so much garbage in kernel config related to USB gadget with similar names. It's hard to tell what's what.
This 24Mhz clock is coming from the CPU ? Maybe time for an external oscillator ? I'll leave the EE stuff to you EE types heh.
