No serial ports for MC7304 after FW Upgrade

[dl5162]

@iochagov

I have a MC7304 upgraded to SWI9X15C_05.05.58.00_GENEU-4G_005.029_000. And after upgrade, no serial ports show up neither on Windows nor on Linux.

Someone should probably add this to the FAQ… It’s been answered multiple times in this forum. See for example:

[SOLVED] ttyUSB not created w Ubuntu or QMI Drivers EM7355

Hello, my EM7355 is refusing to create the /dev/ttyUSB* serial device(s). I have found countless posts similar to this problem and have tried to skim as much as possible from them. The PDFs on source.sierrawireless.com for the EM7355, including SLQS docs, do not provide the in-depth coverage of getting Linux to create /dev/ttyUSB* The firmware previously loaded was for Lenovo, but it needs to have a generic firmware to use SLQS from what I understand? Any help to get this EM7355 to work is…
