Re: pavilion 400-34 usb driver

Hi:

I found the model #.  It is an 034.

Below is the link to the USB 3.0 driver you need.

For future reference, you can use all of the W7 x64 motherboard drivers from this slimline model, which as the same motherboard as yours has.

DO NOT USE ANY BIOS OR FIRMWARE DOWNLOADS FROM THIS LINK
