No serial number for Kindle device
bsdisks uses serial numbers reported by GEOM layer, and strangely enough, for my old Kindle GEOM layer does not show serial number while camcontrol does. As a result, bsdisks does not list serial number. I was trying to fix Calibre working with devices and it uses serial number to identify block devices provided by USB devices it knows. I have a patch[1] to backfill the serial number from CAM layer, but not sure you will want it - I would assume that a proper fix should be to plumb the serial number from CAM to GEOM, but I don't know how to do that.
