Eeek, no, never do that with a device you actually want to use.  This
should be controlled by the cdc-acm driver, not the usbserial driver.
That driver should be auto-loaded for this device, but it looks like the
descriptor is wrong, so it's not binding to it.

Are you able to test a patch and rebuild the kernel to see if we can get
this to work properly?

thanks,
