Which device to attach filter driver to for Xbox 360 controller? -

-

as learning exercise, i'm trying write filter driver wired xbox 360 controller on windows 7 64-bit. controller shows hid joystick, seems should straightforward.

i've made example filter driver mouse swaps left , right mouse buttons. based on moufiltr , firefly samples come wdk. however, i'm having trouble converting example work xbox 360 controller.

when plug controller in, 3 different devices appear in device manager:

  • human interface devices/hid-compliant game controller
  • human interface devices/usb human interface device
  • common controller windows class/xbox 360 controller windows

which 1 of these should attach driver to?

with mouse filter driver, able follow installation directions firefly sample: right-click on mouse in device manager, choose "update driver." xbox 360 controller, i'm not sure device should install driver for. or talking hardware independently, , need install filter each 1 of them?

i should note i've tried attaching filter driver each of 3 devices in order print out ioctls available filter driver. "usb human interface device" filter received no ioctls.

for hid-compliant game controller, received:

  • ioctl_hid_get_collection_information (multiple times)
  • ioctl_hid_get_collection_descriptor (multiple times)
  • ioctl_get_sys_button_caps

for xbox 360 controller windows, receive bunch of ioctls can't track down symbolic name for:

  • 0x80006000 (multiple times)
  • 0x8000e00c (multiple times)
  • 0x8000e008
  • 0x8000a010
  • 0x8000e018
  • 0x8000e014

unfortunately still don't know device should attempting filter. (i hoping 1 of them receiving joystick-equivalent of ioctl_internal_mouse_connect, not appear case.)

i think want filter internal ioctls (specifically ioctl_hid_get_input_report/ioctl_hid_read_report)

you have been filtering evtiodevicecontrol try evtiointernaldevicecontrol , read/get-input report ioctl, originate whatever system service wants read joystick events.

once manage filter right ioctl need @ report descriptor joystick figure out how interpret (and modify) data.

why need use because printers using tprinter prints weird hieroglyph @ beginning of printable area. my problem if send commands, nothing happens. esc e (#27 #69) - sending escape sequence didn't work expected. removed first letter , rest of string made bold. eg. hello -> ello . after changed esc e esc (#27 #69 #27), worked fine. example managed figure out, but... trying select character table "esc t n" (#27 #116 n), make "õäöü" work. command doesn't work. nothing happens! , command supported esc/p, esc/p 2 , 9-pin esc/p, should work fine. manual can found here . if has ever needed use esc/p commands maybe 1 can shed light how work them! thanks in advance! edit: in previous post asked more or less same question though answers how did send commands printer. (i'll change question there according answers!) i accepted ken's answer, because claimed way transferred commands wasn't best , got work escape command. problem after t...
