I worry that a new revision might not help.
Adding any new mandatory CIDs is going to be hard, so I think we can
rule that out as a generic solution. And anything optional won't really
make a difference. It's perfectly possible for one vendor to
standardize new services today, publish the spec and put it up on
http://compliance.usb.org/mbim/. There is no need to make new services
proprietary, even if they are vendor specified.
Unfortunately, only Microsoft seems to understand this. But that's
still somewhat good news. There's a good chance they will want about
the same services we want, and they have the userspace application power
to *force* modem vendors into implementing their services. They actually
have a lot more to say than the USB-IF wrt any optional service and/or
Never thought I'd end up trusting Microsoft to help the Linux community
