PS/2->USB converter doesn't work
Last modified: 2014-03-16 22:25:42 EDT
Using 2.4.9-21 & 2.4.9-28. I have an ATEN UC100KM PS/2->USB converter (plug in PS/2 mouse & keyboard, and then plug the converter into the USB port.) It doesn't appear to work at all under Linux. It works under Windows XP, and in the BIOS (both on ia64 and x86); it does not work in LILO or grub on the x86 box I tried it on. I have tried both the HID keyboard and mouse drivers, and rebuilding the kernel with usbkbd and usbmouse enabled; nothing seems to work. If I look at /proc/interrupts, the USB controller only registers interrupts on device plug/unplug; there appeear to be no interrupts generated when I press keys or move the mouse.
Bill, check the patch linux-2.4.17-usb-55878.patch in kernel HEAD. It may help, but on the other hand, usbkbd worked with that device (when loaded in controlled environment, echo /bin/true > /proc/sys/kernel/hotplug) I did not put it into pensacola or enigma-s390-erratum, do you want it in there? Please test and let me know how it goes. Also, if the patch does not fix the problem, attach your dmesg and /proc/bus/usb/devices.
That patch worked for me ok. Cool, now we can get more machines in the rack attached to the KVM. I don't know that this *needs* to be an errata patch, but it would be nice if it doesn't break other things. (famous last words)
I copied it into errata, so whatever goes after -21 should have it.
