Re: [systemd-devel] WebUSB

I figured that made most sense :) Still, it would be good if we could have a rule to not grab the CDC interface part if the device includes WebUSB functionality. The likelihood of a modem+WebUSB combo is so small that it must fall in the category where potential rare exotic devices combining it

Re: [systemd-devel] WebUSB

A small update: When the modemmanager finishes probing (~16 secs after connection) data seems to stop flowing in from the WebUSB bulk endpoint also. It is, however, possible to reconnect and get data again - so I need to see if there should be anything in the mbed firmware causing that behavior

Re: [systemd-devel] WebUSB

It seemed like if just one interface in the description list was somehow compliant with modem manager, the full device seemed claimed. I may have missed something in my headers while experimenting. Can you give an example of a header structure that will not be assumed to be a modem by MM while

Re: [systemd-devel] WebUSB

I have som more input - but really need Reilly's comments on this: As hardware manufacturers most often want to make it possible for users to use their hardware in a WebUSB setting as well as in a "normal" app mode, we will most likely see composite devices that could have the following
