All drivers are latest, both devices programmed with 1.05 firmware, Microsoft .NET Framework 3.5 also installed.
We try use Programmer with AVR Studio 4 on Atmega128 board. Studio is not see Programmer (but another programmers, from Olimex, work without problem). Now this function not need for us, we don care about.
Also, in Windows “Device manager”, “TTL Serial Port” labeled with “yellow asterisk” (device is can not be used, code 10). Now this function EXTREMELY NEEDED!
I recommend upgrading to SP3 to get a version of the usbser.sys driver that will work with this programmer. Please see this note in the “Installing Windows Drivers and Software” section of the programmer’s user’s guide:
If SP3 is not an option you can try installing Hotfix KB918365 from Microsoft, but it might not work for you.
If that doesn’t work, then I can tell you how to install a different firmware on the programmer that will work with SP2, but you would have to give up the SLO-scope and TTL serial port as long as that firmware is loaded.
