Dude - only 1 minute went by. We don't encourage bumping in general, and 1 minute??? That's getting a bit impatient.

i accidently quoted myself... and decided instead of just leaving the quote to write bump, didnt know what else to write...

Ah, well okay then. ;)

For future reference, if that happens again, you *should* be able to delete the second post if no one has yet responded.

AFAIK, there are two different USB programmable interfaces. Windows should support both. A quick :google: search yields...

CONFIG_USB_UHCI
The Universal Host Controller Interface is a standard by Intel for
accessing the USB hardware in the PC (which is also called the USB
host controller). If your USB host controller conforms to this
standard, you may want to say Y, but see below. All recent boards
with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
i810, i820) conform to this standard. Also all VIA PCI chipsets
(like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
133).

CONFIG_USB_OHCI
The Open Host Controller Interface is a standard by
Compaq/Microsoft/National for accessing the USB PC hardware (also
called USB host controller). If your USB host controller conforms to
this standard, say Y. The USB host controllers on most non-Intel
architectures and on several x86 compatibles with non-Intel chipsets
-- like SiS (aktual 610, 610 and so on) or ALi (ALi IV, ALi V,
Aladdin Pro..) -- conform to this standard.

(This is from the Linux kernel configuration docs.)
