Postup zprovoznění pod Linuxem

Nez zacneme
1. Pokud mame AT board, potrebujeme stitek s USB konektory. Ten v lepsim pripade mame v krabici s boradem; v horsim si z netu stahneme manual k boardu, koupime v bazaru nejaky levny stitek a pokud nebude zapojeni konektoru k desce souhlasit, prelisujeme ho.
2. Najdeme volny USB port. Ve vetsine pripadu je to jedno, ale muze se stat u nekterych znackovych sestav, ze zalezi na poradi obsazovani konektoru.
3. V BIOSu povolime USB a pripojime gamepad. Mela by se rozsvitit LED, tedy vsechno je v poradku. Pro jistotu ho zase odpojime.

Pokracujeme v linuxu
1. V jadre musime mit podporu USB pro svuj HW, dale podporu joysticku a HID
2. Je velice vyhodne mit jadro prelozene s podporou hotplug a mit prislusne balicky.
3. Pokud nepouzivame hotplug, upravime /etc/modules.conf nasledovne:

            # modules for joystick
              alias char-major-13 input
              above input hid joydev
   

4. Pokud pouzivame hotplug, upravime /etc/modules.conf nasledovne:

            # modules for joystick
              alias char-major-13 joydev
   Pripojime gamepad a sledujeme vypis hlasek jadra a soubor /proc/bus/usb/devices. Pokud u gamepadu uvidime driver=hid, je vse v poradku. Pokud ne, hotplug byl spusten, ale nenasel zadny vhodny ovladac (muze se stat u nekterych 2.2. jader), pridame do souboru /etc/hotplug/usb.usermap radek:
            # usb module         match_flags idVendor idProduct bcdDevice_lo bcdDevice_hi bDeviceClass bDeviceSubClass bDeviceProtocol bInterfaceClass bInterfaceSubClass bInterfaceProtocol driver_info
            hid                  0x0080      0x0000   0x0000    0x0000       0x0000       0x00         0x00            0x00            0x03            0x00       0x00               0x00000000
   
   Pokud nemame v adresari /dev specialni soubory js, vytvorime je podle navodu v Documentation/input/joystick.txt napr.:
            # mknod /dev/js0 c 13 0
            # mknod /dev/js1 c 13 1
            # ln -s /dev/js0 /dev/js
   Nezapomeneme nastavit nejaka inteligentni pristupova prava ;)
   
   pozn.: cislo je opravdu 13, narozdil joysticku, ktere maji v 2.2 jadrech 15 a v 2.4 13...
   vyzkousime cat /dev/js a pohneme gamepadem. Pokud vypisuje nejake nesmysly v zavislosti na pohnuti padu je vse v poradku.
   Vyzkousime v nejake aplikaci (treba quake...). Pokud mame vice joysticku a aplikace je nepodporuje, nebo chceme pouzivat jen jeden, vyresime to linkem na spravne zarizeni.
   

Poznámka

Pod linuxem tedy tento gamepad spolehlive chodi. Testovano na SlackWare 8.0.0 a jadry 2.4.14 a 2.2.19 + prislusne utility.
