Hi Jerry,. first of all, sorry for my English, i am spanish and i am not an expert in your language...
My problem is like the one you have solved here, i see my DVD recorder device, but i cant use it because windows doesnīt detect it automatically. Its an error code 10 (the device cant start). I have read that this error code its due to a bad driver installed...a driver from the same company, but not exactly the driver of the product. Here is a screenshot...
Well, I have tried your method to recover my device, but in the registry, i only saw the uppers, and i deleted it, but the lowers entry dindīt appear over there.
After deleting the uppers, i restarted and windows automatically found again the device, but again whit the same problem (error code 10). I tried to delete the device too, and the result is the same. Here is a screnshoot of the registry...
The device name is TRST cnrp CD/DVDW TR-H642L, and i canīt found any driver for it over internet...
Please help me.
PS: Fantastic job, Jerry, its incredible all the things you know!!
PS2: I have continued reading over internet this problem, and someone wrote that his device was burned..:S Its that possible? :S
