If it can be invoked via DBus - what is the harm to only do the scan for the greylisted (in this case webusb) modems when the user actually wants to search for a modem (like a printer) - and leave the poor devices alone otherwise? In headless systems, it will not be the same problem as they will

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

I finally managed to make a configuration that *seems* to work and I realize that I may have had something else blocking the WebUSB interface (2) while modemmanager was communicating with the CDC_ACM interface (1). I made a clean arbitrary VID/PID and get what seems to be a functioning WebUSB

Re: [systemd-devel] WebUSB

For all practical reasons and looking ahead, I truly believe that there will be no reason to have a WebUSB header in any of the few coming modem devices (what are the stats on new USB CDC modems for these years in general? - still enough to justify a "blanket claim as modem"?) as having a

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 don't think we need to change anything in the kernel. What we need is generic udev rule that fixes up permissions for the WebUSB Interface. IIRC, WebUSB is implemented much like CDC ACM, however bInterfaceClass is set to Vendor Specific. That should be enough to prevent CDC-ACM driver from

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
