Legacy USB Support
This is for supporting USB devices under legacy OS such as DOS. When
choosing "AUTO", the system will automatically detect if any USB device is
plugged into the computer. It will automatically enable USB legacy mode when a
USB device is plugged in, and disable USB legacy mode when no USB device
is plugged in.
EHCI Hand-off
This is a workaround for OS without EHCI hand-off support. The EHCI owner-
ship change should be claimed by EHCI driver.
USB transfer time-out
Allows you to select the USB transfer time-out value. [1,5,10,20 sec]
Device reset time-out
Allows you to select the USB device reset time-out value. [10, 20, 30, 40 sec]
Device power-up delay
Maximum time the device will take before it properly reports itself to the Host
Controller. [Auto] uses default value: for a Root port, it is 100 ms, for a Hub port,
the delay is taken from Hub descriptor.
