There was a thread about this same scanner last month.
The author got about as far as you did.
Next you are going to have to do some usb snooping on a windows machine using either http://www.pcausa.com/Utilities/UsbSnoop/ or http://benoit.papillault.free.fr/usbsnoop/.
Then try to figure out the meaning of the snoop logs. Snoop logs are too big to post here, so you will need to find a free web site to post them to. I've used google site for this in the past.
