[Diy_efi] Any USB developers out there?

[Steve Ravet]

This really is EFI related.  I'm working on an open source type hardware
project that will allow connecting a PC to an OBD2 GM PCM via the USB
port.  It'll support 4x mode for reflashing.  I've got a prototype PCB
built but am having problems with the USB enumeration.  Some of the
enumeration info is right but some is wrong, the biggest of which is
that it's being identified as a low speed peripheral instead of a full
speed, even though the pullup resistors are on the right wires.  It's a
microchip microprocessor, which I now recognize to be a poor choice, but
it's what I have.  If anyone has experience with USB, especially
microchip firmware, I could sure use a hand.

thanks,
