That doesn't really make any sense in the way USB works.

However if you've got a system to load and pin firmware *on suspend* and
flush it post resume then you don't actually need special 'firmware'
drivers just a slightly fancier lib/firmware that refcounts and handles
load on suspend/delayed flush.

(and probably a sysctl for cache tuning so that typical small firmwares
get cached on bigger boxes anyway for speed)
