When i try to use fdisk -l it hangs the prozess.

Is there something missig on my machine,

Do you have any other USB devices you could test for successful operation?
When you boot (if using GRUB) you may want to press the letter "a" at the GRUB menu and adding ide=nodma to the end of the kernel options line.

Is the kernel correctly detecting the USB ports and the drivers displayed as loaded with lsmod? Here's sample output you may want to compare:

[mhelios@fc1 mhelios]$ dmesg | grep usb
usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
usb-uhci.c: $Revision: 1.275 $ time 16:46:45 Feb 18 2004
usb-uhci.c: High bandwidth mode enabled
usb-uhci.c: USB UHCI at I/O 0xe000, IRQ 9
usb-uhci.c: Detected 2 ports
usb.c: new USB bus registered, assigned bus number 1
usb-uhci.c: v1.275:USB Universal Host Controller Interface driver
usb.c: registered new driver hiddev
usb.c: registered new driver hid
[mhelios@fc1 mhelios]$ /sbin/lsmod | grep usb
usb-uhci 25740 0 (unused)
usbcore 77984 1 [hid usb-uhci]

dmesg|grep usb
drivers/usb/core/usb.c: registered new driver usbfs
drivers/usb/core/usb.c: registered new driver hub

It doesnīt seem so,
I already updated my kernel,
under /sys are soem usb portslistet

What does `/sbin/lsmod | grep usb` produce? And I assume you've checked that USB is enabled in the BIOS?
