Anybody recognize this error message?

   usb 2-1.5: string descriptor 0 read error: -22

According to:

http://www.keil.com/pack/doc/mw/USB/html/_u_s_b__string__descriptor.html

"String descriptors (USB_STRING_DESCRIPTOR) are optional and add human readable information to the other descriptors. If a device does not support string descriptors, all references to string descriptors within device, configuration, and interface descriptors must be set to zero."

Just sounds like your system doesn't know and is telling you as much.  Look along your second usb bus line, especially if you have a card reader or some such.
