devu-uhci.so

Driver for Universal Host Controller Interface (UHCI) USB controllers


Note: You must be root to start this manager.

Syntax:

io-usb -d uhci [option[,option...]] ... &

Runs on:

x86, MIPS, ARM, PPC, and SH

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.
nosmm
Do not disable system management. Default is disable.
num_ed=num
Number of endpoint descriptors to preallocate.
num_td=num
Number of transfer descriptors to preallocate.
pindex=num
Instance of controller on PCI bus to apply argument.
verbose=num
Set verbosity.

Description:

The devu-uhci.so server provides support for computers that have Universal Host Controller Interface (UHCI) USB controllers. This server creates the /dev/io-usb/devu-uhci.so device.

Examples:

Scan PCI bus for all available controllers.

io-usb -duhci 

If you specify arguments, you must include a pindex argument for all controllers you wish to use. The value of the pindex argument starts from 0.

Attach to the 1st and 3rd controller instance and set the verbose argument on the 1st controller instance as follows:

io-usb -duhci pindex=0,verbose=4,pindex=2 &
