after update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.

the used ports appear to be "killed"; the unused USB ports seem to work, but the Mac works in slow-motion.

The only "solution" is to restart my Mac.

- SMC-reset, PRAM-reset or repairing user rights had no positive effect; what is the solution - a bug-fix-update???

Mac Pro, Mac OS X (10.7.5), USB posts killed?
