Most of it is not specific to STM32 at all.  I had it working on an AT91SAM9
device before.  I know there is an AT91SAM3 based on Cortex-M3, but I don't
know what the USB hardware looks like.  I don't have any other Cortex-M3
micro's around to work on though.  I had a Stellaris board; if I can
find it I'll look
into support for this.

I don't know if there are any big-endian implementation around, the usb
stack assumes the device is little-endian.

Gareth
