Description of problem:
After upgrading to the 2.6.8 kernel, my system no longer recognizes my
16mb Diskonkey USB thumb drive. It seems to be a kernel, rather than
a hotplug, problem since the hotplug version (2004_04_01-1) is the
same as that originally installed by FC2. When I plug the drive into
a USB port, the kernel logs the following lines to /var/log/messages:
kernel: usb 3-1: new full speed USB device using address 22
kernel: usb-storage: probe of 3-1:1.0 failed with error -1
Under the original FC2 kernel (2.6.5-1.358), the following lines were
kernel: usb 1-2.4: new full speed USB device using address 3
kernel: Initializing USB Mass Storage driver...
kernel: scsi0 : SCSI emulation for USB Mass Storage devices
kernel: Vendor: M-Sys Model: DiskOnKey Rev: 2.01
kernel: Type: Direct-Access ANSI SCSI
kernel: usbcore: registered new driver usb-storage
kernel: USB Mass Storage support registered.

I haven't been able to figure out where the "probe failed" message is
generated, so I'm not sure which kernel module is failing. Other
(possibly) useful output is

These symptoms are not limited to one system. It occurs on Dell
desktops (Optiplex GX270, Dimension 2350) as well as my laptop
(Toshiba Satellite A45-S250 and a self-built machine (500MHz Celeron),
so it's almost certainly not a hardware problem.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Plug drive into any USB slot
Actual Results: nothing (see "Description" for messages logged by kernel)
Expected Results: The drive should have been recognized (see
"Description" for messages that should have been logged), and a
/mnt/diskonkey entry should have been added (by updfstab) to /etc/fstab.
I have a similar but not identical problem: the kernel doesn't even
notice that the usb disk is plugged in. The same device works on other
computers running the same kernel. Going back to the original 2.6.5
kernel of FC2 solves the problem, but with this kernel, the on-board
network interface of this computer is not recognized so this isn't
really an option.
I have tried all the usb disks/cameras that I have available, and none
of them causes anything to happen in the logs or the entries under
/proc/bus/usb and /sys/bus/usb on this computer.
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
