I am trying to read a DirectInput Device under Linux.

lsusb:

Bus 003 Device 006: ID 046d:c219 Logitech, Inc. F710 Gamepad [DirectInput Mode]

But sadly no joystick or event is bound :(

How to work around this? Is a custom Windows DirectX Input Driver implementation needed?

  • Do you specifically want to use it in DirectInput mode (instead of the XInput mode)? Commented Sep 3 at 17:22
  • "Only goes up to 7, not 8"? But it starts at ZERO! hidraw0. Commented Sep 3 at 23:51
  • @waltinator There's hidraw8 in the udevadm monitor output though. No idea how that is related to the dev nodes though. (Does it mean /dev/hidraw7?) Commented Sep 4 at 5:25
  • Oh hey you two, sorry for the delay, yes dmesg tells me its bound to hidraw8. Which does not exist because its mostlikey removed due to driver binding failure or something like that (my best guess). Of cause it starts at 0 ;). And I always have 7 (well if i unplug stuff i wont, but nothing changes when plugigng in the usb sim racing handbrake) Commented Sep 4 at 16:58
  • linux-hardware.org/?id=usb:046d-c219&page=2#status Oh and someone on stackoverflow (where my question got closed due to being on the wrong exchange lol) sent me this. So the device is actually, or should be supported? How do I get access to it then though? Hmmmmm Commented Sep 4 at 17:07

I got a workaround reading the raw usb data ->

import usb.core
import usb.util

dev = usb.core.find(idVendor=0x046d, idProduct=0xc219)
if dev is None:
    raise ValueError("Device not found")

if dev.is_kernel_driver_active(0):
    dev.detach_kernel_driver(0)

dev.set_configuration()

cfg = dev.get_active_configuration()
intf = cfg[(0,0)]

ep = usb.util.find_descriptor(
    intf,
    custom_match = lambda e: 
        usb.util.endpoint_direction(e.bEndpointAddress) == usb.util.ENDPOINT_IN
)

assert ep is not None

data = dev.read(ep.bEndpointAddress, ep.wMaxPacketSize, timeout=1000)
print("Data:", data)
