wine users - Jan 2011 - Mobipocket not detecting usb connected ereader

Anyone have pointers on how to get an ereader assigned a PID so it can 
use DRM'd .mobi files? The mobipocket software works great on the 
computer through wine (1.3.8), but when I hook up my ereader to the 
computer through a usb cable the software is suppose to detect it and 
assign it an ID code which lets it open the DRM ebook files. The 
detection is not happening. I can move the files themselves from the 
computer to the reader, but they won't open without the code.
