tried the battery which made no difference. I have checked the device manager and it is showing as unknown device, though it was showing it as working properly. It's not working at all. I have tried to update the drivers, uninstalled the program and reinstalled it, even done a system restore to 2 weeks ago but with no luck. Now running out of ideas. The device was showing correctly even after it went down, but now only will show as above. Windows keeps saying that it's not recognized or not working properly, yet showing ok in manager
