[Gumstix-users] Kernel / Input Subsystem / USB-HID: where is my /dev/input/eventX? Verdex Angstroem2007, 2.6.21

[mr_bunnyman <s_f...@un...>]

Hi Folks,

I'm having some trouble getting an USB Human Interface Device to work on my
qemu-verdex-image, build with Angstroem/OpenEmbedded and based on 2.6.21
without an X-Server. After plugging it in, everything seems to work fine:

$ (qemu) usb_add host:046d:c626
$ usb 1-3: new low speed USB device using pxa27x-ohci and address 2
$ usb 1-3: configuration #1 chosen from 1 choice
$ usbcore: registered new interface driver usbhid
$ drivers/usb/input/hid-core.c: v2.6:USB HID core driver

The driver seems to have loaded:
$ cat /proc/bus/usb/devices
$ T:  Bus=01 Lev=01 Prnt=01 Port=02 Cnt=01 Dev#=  2 Spd=1.5 MxCh= 0
$ D:  Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
$ P:  Vendor=046d ProdID=c626 Rev= 4.04
$ S:  Manufacturer=3Dconnexion
$ S:  Product=SpaceNavigator
$ C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=100mA
$ I:* If#= 0 Alt= 0 #EPs= 1 Cls=03(HID  ) Sub=00 Prot=00 Driver=(none)
$ E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=10ms

But when I try to access the Input-Subsystem to read out movement events, my
problems begin. The /dev/input section is empty/non-existant:
$ ls -l /proc/bus/input/devices
$ -r--r--r--    1 root     root            0 Jul 17 15:31
/proc/bus/input/devices
$ ls /dev/input
$ ls: /dev/input: No such file or directory

I'm using the standard basic-image build with Angstroem 2007 for my
gumstix-verdex qemu image. I found out, that the Kernel-Option
CONFIG_USB_HIDINPUT has something to do with the input-subsystem, but this
option seems to be deprecated since 2.6.19...?

Knows anybody how i get it to work? How can I access my USB-HID through
/dev/input/eventX? Where do I have to look for the appropriate Kernel-Option
to switch the service on? 

Thanks in advance
the bunnyman!
