Hi,
does the Au1000 OHCI controller work for anybody with the current 2.6
cvs tree in big endian mode? When I try to insmod ohci-hcd, the machine
just hangs. Also, I used the attached patch to be able to select usb
ohci even without PCI.
Furthermore, is there any news about the porting of the usb device
driver to the usb gadget stack?
Tom
