Hi,

I'm using fc4 x86_64 smp on an Intel P4 HT with all recent updates
installed.
When I connect an usb barcode scanner, which should behave like am usb
keyboard, I just permanent usb connect-disconnect messages:
(atleast one per second).
usb 3-2: new low speed USB device using uhci_hcd and address 12
input: USB HID v1.00 Keyboard [TechScan Korea Barcode reader(v36a)] on
usb-0000: 00:1d.1-2
usb 3-2: USB disconnect, address 12
usb 3-2: new low speed USB device using uhci_hcd and address 13
...
The device is doing fine on the same machine with the same connection
on windows (XP home) and on debian sarge (2.6.11 kernel), but not with
fc4 2.6.11 kernel.
This renders the device unusable within fedora and i don't know why.

I'v got an ati graphics card with fglrx propertary drivers installed
and serveral usb devices (e.g. logitch usb mouse+keyboard)
successfully connected.
Additionall, i've got "usb-handoff=1" enabled at boot commandline to
let my ps/2 keyboard coexist with the usb one.
When googling for the problem and nearly found nothing but that in
2.6.11-mm there should have been a regression error doing somewhat
similar errors. (http://lkml.org/lkml/2005/8/20/102)
There it's says that the disconnect message should not be seen, but
that's common to me for all usb devices I can unplug.
As its said there that the important things are to debug what's
happing just bevor the disconnect happens, i
reloaded uhci_hcd with debug=1..10 and I got the following additional
messages:
    usb 3-2: USB disconnect, address 16
    usb 3-2: new low speed USB device using uhci_hcd and address 17
    input: USB HID v1.00 Keyboard [TechScan Korea Barcode
reader(v36a)] on usb-0000:00:1d.1-2
