USB diskonkey lost with kernel 2.6.6+?

[Leon Stringer]

Hi,

I used to use my USB key with FC2. I'd plug it in and could use it at 
/mnt/diskonkey.

Unfortunately it no longer works. I think it stopped working when I 
updated my kernel. I'm now on 2.6.8-1.251 (from the Fedora updates 
folder) and when I check /var/log/messages it shows:

    Aug 30 17:47:59 localhost kernel: usb 3-2: new full speed USB device 
using address 2
    Aug 30 17:48:00 localhost kernel: Initializing USB Mass Storage 
driver...
    Aug 30 17:48:00 localhost kernel: usb-storage: probe of 3-2:1.0 
failed with error -1
    Aug 30 17:48:00 localhost kernel: usbcore: registered new driver 
usb-storage
    Aug 30 17:48:00 localhost kernel: USB Mass Storage support registered.

Is there a known issue here? Has the later kernel broken this? Is there 
a workaround?

Thanks in advance for any help,

Leon...
