USB not working: GA-945PL-S3P

hello
i've installed Kalyway Leopard on my pc and everything works fine except my usb ports

it recognized my usb keyboard and mouse, but it can't even see my ipod

my motherboard is Gigabyte GA-945PL-S3P with Intel ICH7/ICH8 USB 2.0

is there any package/kext i could use? i've installed Tiger some while ago and didn't have any problems

also another thing: i have a NTFS partition containing samples for music production in wav format (many many samples), and when i try to load them into Logic Pro it takes a while to read them, and it just freezes

should i convert that partition to XFS?
