MMU2S firmware flashing - device not detected?
Hi everyone,
I’m trying to flash firmware to my MMU2S for the first time, but the control board is not detected. RAMBo flashes fine, but MMU2S shows:
“MMU 2.0 Control device was not found (VID/PID 0x2c99/3 or 0x2c99/4)”
I tried reset button, different USB ports, and both Windows/Linux, but still no luck.
Has anyone fixed this issue before? Any suggestions?
Thank so much! Help me!
