I’d like to use a usb device on an embedded system. I put devu-ohci (I have
got open host controller)on my ifs and launch it. But when I start the
driver for my device there is a time-out when the driver tries to select the
device interface. It seems devu-ohci needs some others process to run
properly…
Could you help me?
Thanks

Nope, all you should need is devu-ohci if you’re sure that’s what you
have. Check to see that your device is listed by typing “usb -v”.
I know I’am right about the devu-ohci because I have written the usb device
driver myself. 
It works perfectly on my devloppment host and I just launch devu-ohci.
But once the driver is embedded the device doesn’t respond… (that’s what
devu-ohci -vvvvv tolds me)

It is certainly a configuration of my usb port… Perhaps should we look
around pci-bios?

Hi
I have possibly the same experience with USB on an AMD Alchemy Au1500
processor I 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:

So, there has obviously sth. been detected.
But if I start
there’s isn’t any output. The system hangs completely.
Any idea?
(I already posted almost this question to the USB group, without answer)
Best Regards
Joerg
