I probably shouldn't tell you this because I *really* want USB support 
in Wine, but you can currently do this currently using a VM. Run your 
application in a Windows in VirtualBox, then you can use Linux's usbmon 
to sniff the traffic.

To do the capture I usually start off with wireshark, and then use this 
command line tool that I maintain:

With a command line packet trace, you can then do greps, diffs, vidiff 
etc. to reverse engineer the protocol.
