Yes I just readed it in your PDF docs, you mention intel P55 but seems that all new intel-based MB's do that way. I downloaded and tried both yours DOSUSB 2.0 and 3.0 but none works.
DOSUSB 2.0 looked promissing, it detected EHCI and also the mass storage device but when I accessed drive letter (just typing D:) it hanged. I tried with and without himem.sys.

EHCI controller installed:
Bus Dev Func I/O      Devices
00/001A/0000 FBFFE000 Port00: device at high speed Port01: no device
00/001D/0000 FBFFD000 Port00: device at high speed Port01: no device

FBFFE000 01 H Unidentified device
     01 is a Hub with 06 ports
     02 H Generic - Mass Storage
FBFFD000 03 H Unidentified device

     03 is a Hub with 08 ports

here's log http://rayer.g6.cz/1tmp/DOSUSB20.LOG
I can read valid USB descriptor of the flashdisk via USBVIEW!
I loaded USBDISK.SYS before via devload.

DOSUSB 3.0 wrongly detected non-existing UHCI even with /e switch

and the log is quite empty, just only "DOSUSB resident now"

So I doubt that any existing DOS driver will work as this intel approach is new and incompatible. The Panasonic USBASPI.SYS was one of the latest developed drivers...
