I used this fine a couple of years back on the same PC and now when reading fuse bits from an Atmega 328 chip it locks up the PC, no keyboard or mouse (they are USB RF ones). I suspect a driver issue? Any tips please? Is it possible to read and write this chip using the serial port, I never have much luck with USB?
The programmers are basic Ebay USB asp's. Extreme Burner (latest version) fails to open the chip at all. The chip works fine in a QRP labs U3S transmitter, so I am confident it's not a dud. Thanks.
