USB not working

Damn, didn't realize my USB is not working in 10.5.8.
Most probably, which i suspect, is the seatbelt.kext and System.kext problem.

Stupid me didn't keep my backup and deleted them.
Gonna get it back from a friend on his MAC and reinstall them and try again.

Damn.

===============================

Ok, got it working again. So here's what i did :
From 10.5.8, got:
- seatbelt.kext
- System.kext
- mach_kernal Voodoo version based on 9.8.0

From 10.5.6, got:
- IOUSBFamily.kext
- IOUSBMassStorageClass.kext

Installed them using OSx86Tools.
Reboot with -v -f

And all seems working now. (Hopefully)
