I have downloaded the latest AVRUSB software (v2.1. 4 on) and I get FTDIXX2.DLL error. What is the problem?
Either the programmer hardware has not been plugged in before the AVRUSB software is run or an older programmer is being used without an older version of AVRUSB software on PC. Please contact support to obtain an older version of software. Once AVRUSB has connected with older software, the latest software can be installed and it will automatically update programmer hardware.
