Your guess is right, unless some specific wiring is done on your board.
As a begining, I would advice to :
- check arch/arm/mach-pxa/mioa701.c or arch/arm/mach-pxa/magician.c
- pay special attention to :
* in init function :
pxa_set_udc_info(...);
UP2OCR = UP2OCR_HXOE;
* everything containing "gpio_vbus"
* everything under the comment "USB UDC" in mioa701.c
- don't forget GPIO declaration in the big static gpio table (the one passed as
argument to pxa2xx_mfp_config).
- make a try, and come back to report
Good luck.
