I made the mistake of telling Windows (7) it could update my drivers for me, now the toy has stopped appearing on Device Manager as COM Port 3 / IRToy, and is now a 'USB Input Device'.
Wow, thanks Transmission, I think you may have uncovered an unknown WIn7 problem people are having with the IR Toy. I have never seen the update drivers prompt. JermZone did you also have this happen?
Is the LED lit all the time too? If that is the case you might be stuck in bootloader mode. Did you try either of these tricks from the FAQ:viewtopic.php?f=29&t=3572Q. My IR Toy was working fine, but now it doesn't connect to the USB port. Is it broken?
A. A firmware update will often fix this. Connect the PGC and PGD pins of the ICSP header with a bit of wire and plug in the IR Toy. It should show up as a USB HID device. Then run the update program available here
.Q. The IR Toy is stuck in upgrade/bootloader mode. It appears as a USB HID device and the indicator LED (I) is on. How do I get out?
A. Upload the latest firmware over USB to get unstuck. Once you jump to the bootloader by typing $ in the terminal you must complete an upgrade, or exit cleanly with the fw_update application, or it will stick in the bootloader mode.
