EM9191 fails to appear on USB, in an Ubuntu 22.04.2 environment, on a M2 KeyB socket and supposedly capable motherboard. “lshw”, with and without the module, do not differ significantly. The module appears “warm”, to the touch. A M.2 NVMe is mounted on a separate M2 KeyM socket, and working.

How to verify the EM9191 starts up properly?
