and I cannot mount flash pen with usb_storage.

If I remove ehci and I only use uhci usb_storage detects the pen and I
can mount it.



Version-Release number of selected component (if applicable):
kernel-2.6.6-1.435.2.3

How reproducible:
Always

Steps to Reproduce:
1.modprobe usb_storage
2.mount /dev/sda1 /mnt/flash ==> error

    

Additional info:

Same problem with the older FC2 kernel.
It worked fine with FC1 (also updates).

I have also tried with a custom kernel and I got the same result
