You'd issue probe from FreeBSD to USB device using whatever tools, & the (Gasp! Wash my mouth out with soap!) - MS.EXE prog running on a 2nd PC would trap a copy of traffic in each direction, synchronising the 2 as well I believe though never tried it. The 2nd monitoring (MS) PC uses 2 USB ports, one to copy FreeSBD PC to tablet device traffic, & the other port to copy tablet to FreeBSD traffic. ... & you have to make up a special USB cable, eg a male to female USB extender cable, with tapped copies of signal in each direction going to 2 extra USB connectors to 2 ports on 2nd monitor PC. Sane developers seem to do that a lot on new unknown USB scanners. > but I know darn well you're right more often than I am, so I > will give a good look at that list anyhow.
