If you think you're only running at Full Speed because of the warning 
from Windows that says something like
   "This hardware is not performing at optimum speed.
    Try using a high-speed USB port."
then you probably DON'T have a problem.  The USB programmer has problems 
being recognized properly.  I have no idea why this problem still 
lingers after all these years but I certainly hate seeing it.  It took 
me days before I was comfortable that it was actually running at the 
higher rate.

Silly stuff.

Hello,

I'm working with a new xup rev. 04 board: Whenever I connect the
integrated USB Platform cable I only get USB full speed (1.1) although
I need the faster USB 2.0 connection.

I tried 4 different machines, 3 different operating systems (VIsta,
WinXP SP2, Ubuntu) even switched the USB A-B cable -- various
combinations tried. The XUP board connects with 1.1, while in
each and every case my Spartan 3E starter kit connects with USB 2.0.

The vendor ids:

  Spartan3E : ID 03fd:000d Xilinx, Inc.
  xup-v2p:       ID 03fd:0009 Xilinx, Inc.


I could post the usb endpoint configuration as reported by linux, but
I
cross checked with the Cypress EZ USB datasheet, and the USB
1.1 configuration for the xup looked like the one in the Cypress
datasheet,
when cypress decides it must do usb 1.1.

Any ideas how to proceed?
