Upgrade to parallels 4 / USB key (midenty - kobil) is not recognized

Hi I have been using version 3 of parallels on a macbook with very little problems
I could use almost any usb sort. Including a midentity usb stick from kobil

After the upgrade proces to version 4 this usb stick is not working anymore. It is not mounted in Mac OSX or within Windows XP guest.
What I get from the log is the following error message.

27/07/09 23:47:23 kernel USBF: 80.149 [0x6d64200] The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 1 of hub @ location: 0x24000000)

I cannot find any solution for this 'enumerating a USB '
Any help would be very much appreciated
Thank you
