 AFAICT, i failed to properly protect sc_q when converting this
 driver on the usbmp branch, and this is likely a list being
 updated while also traversed.  i don't have a fix, but it should
 not be a big deal.
 there might also be the same problem in some of the other drivers
 so i plan to survey them all that i've updated for this (there
 aren't many to check, fortunately.)
 of course, anyone else is else welcome to look at this, i may
 not find time for a week or more.
