It has 6 pins and it is very near to USB-P test point and sync connector.

Unfortunately, I didn't find any 6 pin chips to be connected in any way to the testpoints - but don't stop testing on your own time - I may have missed something.
Chris - We have the driver for WM2003SE - I'm sure it was in the A02 firmware. It was removed from the newer releases. I have no idea what to use for WM5 though. Something would need to be scarfed from another WM5 PDA with a USB host interface.
I'm going to pull apart some cheap USB hubs this weekend to see if I can get the transient suppression interface chip needed for this.
