MMU2 board flash failed

Has anyone tried to flash the MMU2 board with the fw 0.9.0 provided together with the last 3.4.1 Einsy fw ?
I get an error and it won't install.
Einsy fw 3.4.1 installed first with no problems.

Using Slic3rPE-1.41.1-rc+linux64 and micro usb between board and PC.

Re: MMU2 board flash failed

I had the same issue and found the modemmanager udev rules that are in the readme fixed the issue. Thanks for noting it here.

RE: MMU2 board flash failed

I had the same problem, editing the file "99-mm.rules" as suggested by @andre-l9 solved it
