Ah, fun :(

So, we can add a quirk into the kernel cdc-acm driver to never bind to a
device that has the wusb platform capability descriptor, which will
prevent you from having to disconnect the driver from the device (and
the permissions issues involved in that.)

Would that help out?

And just do the same thing in modem manager, never grab a device with
this descriptor, and let the browser/webusb handle the control of the
device if it so desires.

thanks,
