US-20x20 firmware update error

[mathieujm]

I just bought second-hand and US-20x20 interface. It's perfect for my needs and has 0 problem. The sound is fine. But...
The firmware is V1.01 and there is a V2.0 available by Tascam.
Ok, I downloaded it and tried to install. I can't because of a "Hardware checksum is not valid" message.
Do you know what the problem could be ? Thanks

J'ai trouvé la solution. Il suffisait de mettre le Us-20x20 en position Mixer et tout est ok
