USB for a non-PCI system

How am I able to take the USB manager devu-ohci into use if there’s no PCI
bus? We have a SH4 board, which has only one bus, with all the peripheral
(inc. USB driver) attached to it and I would like to give the devu-ohci the
base address of the USB registers as parameter, but there’s no such
parameter.

Martin,

Try: devu-ohci -a[base address] -i[interrupt]

-Jay.

Thanks Jay, I’m now able to start the driver and I get the /dev/usb entry.
Funny thing that these parameters aren’t mentioned in the help
documentation…
