CWUSBUHC.SYS

UHCI compliant host controller driver by Chris Wohlgemuth is based on the sources available on the DDK site. It does not have the feature set of the latest IBM driver. If you already have a (maybe better) working driver from there feel free to use that one. Unlike the latest IBM drivers only one controller chip is supported with this driver. When loading this driver twice you system may freeze when attaching an USB device.

Use this driver if your USB controller chip is UHCI compliant (for example Intel and VIA chipsets). Refer to your mainboard documentation if in doubt. BASEDEV=CWUSBUHC.SYS

Parameter

 * /V - Verbose, show some information while booting.
 * /FS - Forces driver to stop USB host during OS/2 shutdown process. This parameter can be used to prevent POST (power on system test) failure on some hardware with legacy keyboard.
