Dead USB Ports

[ciuchka]

Hi all.
I have a late 2009 Macbook White.
I recently used an USB hub that (i think) it was faulty.
My Macbook shut down without any warning... poof.
Restarted fine but my 2 USB ports stopped working.
I tried all this:
- Used Apple Hardware Test. (no errors, all good).
- Left it 30 minutes without power cord.
- Booting Windows XP on bootcamp.
- Boot with 10.6.1 disc to see if an external USB keyboard would work.
- Boot in safe mode.
- Create new Admin User.
- Press and hold power button until led blinks on startup.
- Resetting SMC.
- Resetting PRAM and NVRAM.


There was another thing to do: remove battery. Can`t do that because I don`t have the necessary screw driver (triangle thingie). Any extra help?
Thanks in advance.

sounds like a logic board problem, since you have tested just about everything possible.
(removing battery wont help either, it does essentially the same as pram reset.)

i would bring it to apple and let them take a look at it.

But it shows up in the System Profiler...
USB High-Speed Bus:

Host Controller Location: Built-in USB
Host Controller Driver: AppleUSBEHCI
PCI Device ID: 0x0aa9
PCI Revision ID: 0x00b1
PCI Vendor ID: 0x10de
Bus Number: 0x26

Confused...
