I have a project where I have to upgrade the OS from 32bits to 64bits (Ubuntu 12.04 to 20.4) in more than 5K devices. The modem MC8090 is working fine with Ubuntu 12.04 however once upgraded to 20.04 there is no communication.
In few cases it work fine and the only difference observed is when running the command “lsusb” the OS will read the modem as MC8700.
Any solution on the above scenarios to make the modem work under 64 bit architecture?
Any recommendation on which firmware support 64bit for the modem?
