hi , I am french so sorry for my english.

I am runing Snow Leopard. 10,6,8

I am trying to get me usb working in usb2, now it s only working in usb1 mode, 18min transfer for 1000mo.
I dont know what to do at all, bios ? kext ?

please I need your help

The fix:

Delete AppleHPET.kext from /System/Library/Extensions

USB is flying and my systems sleeps and shuts down!

Quick and dirty:
Using Finder, copy the Kext to the desktop or somewhere as a backup (or you can use OSX86Tools too). Better be safe than sorry!
sudo rm -r /System/Library/Extensions/AppleHPET.kext
