Can you use 'git bisect' to track down the offending commit that causes
it? It shouldn't take too many tries.

Very likely this change:
commit b37d83a6a41499d582b8faedff1913ec75d9e70b
usb: Parse the new USB 3.1 SuperSpeedPlus Isoc endpoint companion descriptor
I'll send a series with fixes for usb-linus today, including the fix for this one.
On second thought, it's probably better to just send the regression fix
