Bug Description
When I connect my nexus7 to my raring desktop, modemmanager monopolizes it for half a minute before I'm able to use it:

Is there some way that modemmanager could detect more quickly that it's not talking to a modem?

Yes!
I had seen this, but then could not reproduce for some reason, and asked ogra about it, who said he didn't notice the problem.
I was already planning to blacklist it, there's a patch ready or already enough information to do so, with the advantage that it's a default USB ID used in the kernel and only for g_serial -- it should be safe to blacklist, and those using it and really expecting ModemManager to claim the device can easily drop the blacklist.
Triaged/High. It's kind of annoying for anyone playing with the nexus 7 images.
