2015-03: 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
USB interface
TODO: solder wires to USB port and/or order cable

Die
No maker's mark observed on die. There are some foundry marks but that probably won't be very helpful even if the foundry is identified
