Hi everyone
does anyone have any experience with devu-ohci for non-PCI?
I use an AMD Alchemy Au1500 processor and start the stack after enabling
the onchip OHCI by
devu-ohci -vvvv -a 0x10100000 -i 0x8004001a &
This give the following output:
control 5e040000, headp 1023251, tailp 1023250
Error on Control transfer : Device not responding
Error on Control transfer : Device not responding
control 5e040000, headp 1023211, tailp 1023210

After inserting an USB device (e.g. mouse) the output is:
Jan 01 00:01:33 2 12 0 CLASS_EnumerateDevice: parent 0, port
1, speed 1
Jan 01 00:01:33 2 12 0 CLASS_EnumerateDevice: Get device

Jan 01 00:01:33 2 12 0 udi_in_out: devno 1 inserted
So, there has obviously sth. been detected.
But if I start
usb
there’s isn’t any output. The system hangs completely.
Any idea?
