I don't know what it does exactly. The comment in usb_quirks.h just 
says "modem device breaks on cm over data". I do know that it's needed for a 
lot of cellphone and modem-type usb devices (including my Samsung VI660 
(anyone feel like committing usb/74880?)). I tried my V620 with the ubsa 
patch but without the quirk and it didn't work at all.

It doesn't look like this was ever MFC'ed. Who should I bug to get that taken 
care of? If I can test it and it takes care of the error messages then I'll 
add it to my patch and submit a PR.

Funny coincidence. It looks like kern/106033 (the PR that led me down the ubsa 
path to begin with) was committed a few hours before my message yesterday. 
Thanks Lukas!
