  • Adds support for GPD Win Max.
  • Adds support for GPD Win 4 2023 (7640u/7840u) versions.
  • Adds support for GPD Win 4 2024 (8840u) version.
  • Adds support for GPD Win 5 2025 (HX 370)version.
  • Adds support for GPD Win Mini 2025 version.
  • Adds back paddle support. GPD Win 4 and Win 5 devices use the same back
    paddle device as the win mini.
  • All devices have a dedicated guide button. Remove the QAM mapping to
    allow full support of both paddles. (Win Mini, Win 4, Win 5)
  • Generalize the driver name for the GPD paddle device.
  • Remove unused GPD capability maps, rename gpd4 -> gpd2.

GPD Win Mini 2025: I'm able to access OGUI in game mode now and inputplumber device 0 is showing as GPD WinMini. Trackpad no longer functions in both game mode and desktop mode. L4 and R4 buttons are still not mappable and are not displaying in inputplumber device test.

GPD Win Max 2 2025: Buttons, back paddles, and trackpad are all working as expected. Able to access OGUI in game mode, but not able to map the back paddles, and inputplumber device 0 is showing as GPD WinMax2

Can you hold guide and use the track pad? The win mini has a track pad driver and for some reason Valve has the deck configured such that the mouse activity doesn't work in the steam UI, just in desktop or in game, unless you hold guide.

GPD Win Max 2 2025: Buttons, back paddles, and trackpad are all working as expected. Able to access OGUI in game mode, but not able to map the back paddles, and inputplumber device 0 is showing as GPD WinMax2

Holding the menu button and using the track pad isn't working both in game mode and desktop mode.

To make paddles work, L4 and R4 should config to PrtSc/SysRq and Pause. If you used Handheld Daemon and used the F20/F21 configuration, you might need to restore that.

I'm using GPD Win Mini 2024 8840U, and track pad is also not working.

can you do inputplumber device 0 test and confirm it isn't working in the tester?
