--03: I have a polished python libusb driver for these
-Info I've collected on the dental x-ray sensors that I got from UNIXSurplus at DEFCON 22.  These supposedly use USB.  Manufacturer or any other details unknown.
-WARNING WARNING WARNING
-Bond wires are exposed!  Be very very careful handing these!
-WARNING WARNING WARNING
-JM inventory:
-  * Unit: bond wires partially covered in glue.  Wires in perfect condition / intact
-  * Unit: bond wires ruffled but looks okay
-  * Unit: bond wires overall in good condition.  HOWEVER, a small section was ruffled and a wire broke (PCB side).  As they are aluminum I don't know if I can solder it
-  * Unit: bond wires in good condition.  No scintilator (and it looks like it never had one: no glue marks etc)
-  * Unit: in overall very poor condition.  No bond wires.  PCB has severe damage.  Sensor has severe damage.  Scintilator is damaged and separated from sensor
