I unplugged my USB scanner several weeks ago and suddenly the rear USB ports quit working. They're completely dead functionally, but when I run the Hardware test, it says "No Problems Found". This tends to give me some hope that I can revive them, but I've tried the SMC reset and zapped the PRAM several times with no effect.

Lucky for me that the front ports still function, but it's very disappointing that just unplugging a device would kill three ports. Does anyone have any suggestions to add?
