A little old, but okay. > [EMAIL PROTECTED] ~]# lsusb -v ... This listing didn't contain any information on your keyboard and mouse! That's what I need to see; so the KVM has to be set to connect them to the computer when you run lsusb. > [EMAIL PROTECTED] ~]# dmesg ... > usb 2-2: new full speed USB device using uhci_hcd and address 2 > usb 2-2: configuration #1 chosen from 1 choice > hub 2-2:1.0: USB hub found > hub 2-2:1.0: 4 ports detected > usb 2-2.1: new low speed USB device using uhci_hcd and address 3 > usb 2-2.1: configuration #1 chosen from 1 choice > input: BTC USB Multimedia Keyboard as /class/input/input2 > input: USB HID v1.10 Keyboard [BTC USB Multimedia Keyboard] on > usb-0000:00:1d.1- > 2.1 > input: BTC USB Multimedia Keyboard as /class/input/input3 > input,hiddev96: USB HID v1.10 Device [BTC USB Multimedia Keyboard] on > usb-0000:0 > 0:1d.1-2.1 > usb 2-2.2: new low speed USB device using uhci_hcd and address 4 > usb 2-2.2: configuration #1 chosen from 1 choice > input: Logitech Trackball as /class/input/input4 > input: USB HID v1.10 Mouse [Logitech Trackball] on usb-0000:00:1d.1-2.2 > usb 2-2.3: new low speed USB device using uhci_hcd and address 5 > usb 2-2.3: configuration #1 chosen from 1 choice > input: No brand SP04-A1 as /class/input/input5 > input: USB HID v1.10 Keyboard [No brand SP04-A1] on usb-0000:00:1d.1-2.3 > drivers/usb/input/hid-core.c: couldn't find an input interrupt endpoint These are the devices going to the KVM switch, right?

Yes; the devices get disconnected from the computer when you change the KVM switch. > When I switch to the system the following message is displayed on the > console: > > drivers/usb/input/hid-core.c: couldn't find an input interrupt endpoint The same error occurred during bootup.
