I use a Pro-Micro as ISP Programmer and AVRDudess software.
Recently, I’m unable to detect ATMega32u4; new board or (old) working board, all I got is “Unknown signature”.
I tried this on an AT90USB646 board, and AVRDudess detected the board
I suspect something happen to the driver, maybe Windows update is related.
Has anyone encountered this problem? do you have a solution for this?
Thank you for reading.
