This is exceptionally weird because it just happened as a result of updates (either to OS or Steam) but this pdp xbox one controller that I use just stopped taking inputs and an old fake xbox controller still works?

so something is affecting the driver?

I don't want to install xboxdrv because the precision and latency when using this software instead of native detection is worse.

also it requires more preparation whereas I use my computer for lan parties (of Towerfall and the like) and it's just better for everyone when I have plug-and-play functionality.

Anyone know why this might be occurring and how to fix it?

here's my sys info gathered by steam :

Recent Failure Reports:

I went into steam big picture to try and solve this and enabled detection of all controllers. but while my pdp controller shows up, it shows up as "generic gamepad" and does not take any inputs, I tried configuring it but it still detected no movement of the joystick and didn't respond to any button, while the other controller navigated all the menus with ease.

I'm also having this problem. I tried installing the xboxdrv, but that just made Steam stop recognizing the joystick.

I've got a PDP xbox controller, it does show up in lsusb.
I checked the xpad driver, and it lists support for my particular controller. Is yours in the list?
