It bisected down to this:

commit a2582bd478c13c574d4c16ef1209d333f2a25935
Author: Russ Dill <russ.dill@...il.com>

    USB: Close usb_find_interface race
    
    USB drivers that create character devices call usb_register_dev in their
    probe function. This associates the usb_interface device with that minor
    number and creates the character device and announces it to the world.
    However, the driver's probe function is called before the new
    usb_interface is added to the driver's klist_devices.
    ...

and what's even scarier is that that commit is marked for stable too. Did 
it already make it?

I'll double-check by reverting it from current -tip, but if you don't hear 
anything different from me, you can assume that that double-check 
succeeded and confirms that that commit really is the cause of my printer 
no longer working.
