basepri="5..252"

Set the priority of threads not fixed by the USB or SERVICE subsystems.

latency=n

Sets the read latency timer to a value in milliseconds. Valid values are 1 through 16. if the parameter is not specified then the default value is hardware-specific.

ncbs=x

Parameter deprecated and has no effect. Do not use.

ntrans=x

Parameter deprecated and has no effect. Do not use.

Remarks

Channels are installed beginning at the "first" parameter. If that channel is already taken, the channels are installed starting at the first available position. Consequently, care must be taken to ensure that devices of one type are installed in consecutive positions by plugging like devices into adjacent USB hub ports. Uninstalling a device driver or unplugging the USB device frees the allocated channels for use by other drivers.
