Does this mailing list is right for ask the question below ?

My system:
- Dell C600 Laptop with BIOS upgrade A23 (latest)
- Kernel 2.6.7 (without patches)
- XFree86 4.3
- ACPI turned on
/boot/grub/menu.lst (just the kernel default)
kernel (hd0,5)/boot/vmlinuz-2.6.7 root=/dev/hda6 noapic devfs=mount
acpi=on resume=/dev/hda5 vga=791

	Attached is the dmesg output, and the lines of /var/log/messages
related to the issue (mess file)


    When the system is turned on from the power off state, everything
works fine.
     If I do a "echo 4 > /proc/acpi/sleep" (suspend to disk), the system
goes to hibernate. Ok again.
     But when the system is turned on again, the external USB mouse
doesn't works.
      Before the system goes to hibernate, I had a look to /dev/input/ and
there are: /dev/input/mice /dev/input/mouse0 and /dev/input/mouse1
/dev/input/mouse2, when the system come back from hibernate, /dev/input
reports /dev/input/mouse0 /dev/input/mouse1 and /dev/input/mice and the
USB mouse doesn't works. Even if I switch to tty1 (ctrl  F1) and unplug
/ plug the usb mouse doesn't works.

	Can you suggest something ? Is it a issue for: Dell BIOS, Linux Kernel,
XFree86, ACPI code ?

Thank you very much
