Options:
- ioport=addr
- Register the base address of the USB controller. The default is to scan the PCI bus.
- irq=num
- The interrupt request number.

- num_ed=num
- The number of endpoint descriptors to preallocate.
- num_td=num

Description:
The devu-hcd-uhci.so server provides support for
computers that have Universal Host Controller Interface
(UHCI) USB controllers. This server creates the
/dev/usb/devu-hcd-uhci.so device.
Note:
If you specify options, you must include a pindex option
for all controllers you wish to use.
Examples:
Scan the PCI bus for all available controllers:
io-usb-otg -duhci
Attach to the first and third controller instance and set the
verbose option on the first controller instance as follows:
io-usb-otg -duhci pindex=0,verbose=4,pindex=2 &
