Bug#248855: Useful clues for non-working USB keyboard on SunBlade 150 / sparc64
Today I downloaded "the most up-to-date" debian-installer/sid CD image from:
http://cdimage.debian.org/pub/cdimage-testing/sid_d-i/sparc/20041206/sarge-sparc-businesscard.iso
As always, it booted correctly, but the USB keyboard was unusable.
Being desperate I tried to find information how to preseed a
kbd-chooser/kbd/usb parameter to the d-i but I was unsuccessful.
However, I thought finally to check the source code of the kbd-chooser.
I found a file "usb-kbd.c" in the location:
http://d-i.alioth.debian.org/svn/debian-installer/packages/kbd-chooser/usb-kbd.c
and, Halleluiah, there is something:
===
if (((p = strstr(buf, "usbhid")) != NULL) &&
((p = strstr(buf, "Cls=03")) != NULL) && // Human Interface
Device
((p = strstr(buf, "Sub=01")) != NULL) && // Boot Interface
Subclass
((p = strstr(buf, "Prot=01")) != NULL)) { // Keyboard
===
I tried to check /proc/bus/usb/devices file (first I needed to mount
usbdevfs)
and look what I got:
===
# mount -t usbdevfs usbdevfs /proc/bus/usb
# cat /proc/bus/usb/devices

So it seems that kbd-chooser only chooses USB keyboard if in the
/proc/bus/usb/devices there is a "Driver=usbhid". I suppose that on some
architectures this is correct, but on SunBlade 150 / sparc64 there is only
"Driver=hid". The rest of the information (Cls, Sub, Prot) is fine.
A small patch and maybe kbd-chooser will finally work on this machine?
I mean: choose an USB keyboard if "Driver=usbhid" __OR__ "Driver=hid".
Please notify me about any progress.
Best regards,

PS.
Sorry for the noise (sending this e-mail to so many people),
but if it's going to work... "it's a very exciting time" :-)
