Problem with KVM and USB mouse

[Jan Morales]

I am experiencing some frustration using a KVM and a USB mouse, which I 
am finding is not unusual. I have searched the archives and bugzilla and 
I haven't found any mention of my particular issue.

What happens is that, under normal use, the mouse will freeze 
intermittently, but often enough to make it unusable. After reboot, the 
mouse will work well for several minutes, but after the first freeze 
they will recur very frequently. What appears in dmesg when the freeze 
occurs is dozens of the following line:

drivers/usb/input/hid-core.c: input irq status -84 received

The red light in the mouse turns off. The mouse will light up and 
unfreeze when I switch the KVM to the other PC and back to this one. The 
following lines are recorded in dmesg when I do this:

usb 3-1.1: USB disconnect, address 18
usb 3-1.1.1: USB disconnect, address 19
usb 3-1.1: new full speed USB device using uhci_hcd and address 20
hub 3-1.1:1.0: USB hub found
hub 3-1.1:1.0: 4 ports detected
usb 3-1.1.1: new low speed USB device using uhci_hcd and address 21
input: USB HID v1.10 Mouse [Microsoft Microsoft 3-Button Mouse with 
IntelliEye(TM)] on usb-0000:00:1d.1-1.1.1

As I said, once I do this the mouse will work for a very short time, 
usually less than a minute, before freezing again. I tried disabling 
hyperthreading and running the non-smp kernel, but the freezing occurs 
either way.

Is there a patch, fix, workaround, etc. for this?

I have attached my startup dmesg output. The system is a Dell Dimension 
8400 running FC3, up to date. The KVM switch is a Belkin OmniView SOHO 
Series 2-Port KVM Switch with Audio (F1DD102U). The mouse is a USB MS 
Optical Mouse. The Windows system on the other end of this KVM does not 
exhibit this problem.

P.S. As an aside, if anyone can recommend a KVM for DVI, USB or PS/2, 
that actually works at 1600x1200, 60Hz on a 20" LCD display, I'd love to 
hear about it. This unit has one other serious flaw, but it's not 
FC-related. I have tried two other KVMs which were actually worse.
