Description of problem:
I ran kernel 2.6.5 and my Sandisk Cruzer micro USB 2.0 flash memory
worked fine. But when I upgraded to 2.6.8 doesn't works.

I tried with: mount /dev/sda1 /mnt/usb
but recieved the error message:
mount: /dev/sda1 is not a valid block device

I tried to find out where the error was and that I found was the
message I got when I wrote 'dmesg' as root.

(The message)

[...]
ACPI: PCI interrupt 0000:00:1d.7[D] -> GSI 11 (level, low) -> IRQ 11
ehci_hcd 0000:00:1d.7: EHCI Host Controller

I hope that you can manage this problem.
