Access method switches (continued)
Description Switch
Forces USB support to start, even when the USB controller is being
run by something else (DOS only).The -forceusb switch attempts to
take over the USB Host Controller and then attempts to return it to
the previous state once the Ghost operation is complete. This works
for controllers as follows:
■
EHCI controllers with BIOS support are taken over and then
returned to the BIOS.
■
UHCI controllers with BIOS support are taken over and then
returned to the BIOS.
For example, the keyboard is returned after the Ghost operation
is finished.
■
OHCI controllers with BIOS support are taken over but not returned
to the BIOS.
Note the following:
■
Use this switch with caution.
■
Avoid using the forceusb switch to take over a USB controller from
a driver, for example, the Ghost peer-to-peer USB driver. You may
encounter problems if you do this.
