I have a Colibri PXA310 module with WinCE preflashed. I will test what
USB ports it supports on monday.

Think I found it (20 pages). It says:

Colibri PXA300 only:
  - USB 2.0 device (requires external UTMI chip)
Colibri PXA310 only:
  - Built-In USB 2.0 device transceiver

And further down:

1.4.1 Colibri PXA310 only:
Wolfson WM9715L Audio-Codec

SMSC ULPI Transceiver USB3329

Fairchild USB Transceiver USB1T1105

So, couldn't it also be the Fairchild tranceiver? Or both??
