Hi, I am having trouble with an IOGear (Aten) Miniview II USB KVM switch. I am running 2.4.10 kernel although I ran into the same problems on 2.4.13. The problem is that neither the keyboard nor the mouse plugged into the KVM switch is recognized, although the same mouse and keyboard plugged directly into the computer work just fine. I have tested the switch under Windows on the same machine and it works, so the problem is not hardware. I have tried each of the modules usb-uhci.o, uhci.o, and usb-ohci.o without any luck.
Has anyone else run into this problem before or have any suggestions about what to do about it? I should also mention that if the kernel is compiled without USB support, the keyboard works through the switch just fine, but the mouse does not. I presume (with my very limited knowledge of the USB subsytem) that in this case BIOS is handling all the USB stuff. Below is a copy of my /proc/bus/usb/devices file with the KVM switch plugged in. Below that is a snippet of /var/log/messages which is written when the uhci.o module is loaded. Btw, I have a PIII running on an ASUS CUV4X motherboard. thanks, Mark T: Bus=02 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2 B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0 D: Ver= 1.00 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0000 ProdID=0000 Rev= 0.00 S: Product=USB UHCI-alt Root Hub S: SerialNumber=d000 C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub E: Ad=81(I) Atr=03(Int.)
