M52259EVB USB mass storage

I just started running the Web-Hvac lab on the M52259EVB, with DEMOCFG_ENABLE_USB_FILESYSTEM=1 to test the MQX mass storage handling. Everything else in the lab works fine, but it does not recognize the Freescale memory stick. In fact, it never sees a USB event when the stick is inserted or removed. The stick works fine in a PC, it gets power (its LED lights), and I've checked all the jumpers.

 

So my question is whether this part of the lab is really supposed to work? Is there anything other than the above define in hvac.h that needs to be set up? Should this part of MQX work right from the installation DVD?

 

Thanks in advance!
