Hi
I'm not sure about the TS-7800 but i did some looking around on my
desktop computer last week. Have you looked at /proc/interrupts
(assuming a 2.6 kernel)? It should contain some interrupt for the usb
and you should see the count going up for every keypress and release if
it's working at all.
cat /proc/interrupts gives me: (on my desktop comp...)
CPU0 CPU1
0: 20978955 0 IO-APIC-edge timer
8: 1 0 IO-APIC-edge rtc
9: 0 0 IO-APIC-level acpi
14: 752347 0 IO-APIC-edge ide0
50: 15503 0 IO-APIC-level uhci_hcd:usb2
58: 219985 0 IO-APIC-level uhci_hcd:usb3
169: 14189119 0 IO-APIC-level eth0, nvidia
217: 264894 0 IO-APIC-level libata
225: 50160 0 IO-APIC-level Intel ICH7, uhci_hcd:usb4
233: 3 0 IO-APIC-level uhci_hcd:usb1, ehci_hcd:usb5
NMI: 5643 5329
LOC: 20978612 20978755
"dmesg | grep -i usb" includes the following:
usb 2-1: new low speed USB device using uhci_hcd and address 2
usb 2-1: Product: Dell USB Keyboard
This gives me reason to believe that my keyboard is generating
interrupts at interrupt line 50. Looking at /proc/interrupts after
pressing and releasing a key should increase the number by two.
(Fortunately every USB hub seems to generate interrupts on one line each
and since I have separate hubs for each connector i can trust this not
to include mouse events etc. In your case it should be even simpler if
your only connected USB device is a keyboard)
B.t.w. I assume that you have also loaded usbcore and input or that you
have them compiled in the kernel. If interrupts are generated but no
/dev/input can be found I would check this out since I can see no other
reason that it shouldn't work.
This was no manual for success but I hope this helps you track down the
issue by yourself.
Best regards
