I can’t say I ever did. The device appears to load successfully with the hid-generic driver, and the i915 driver even visibly comes into play when I connect a screen, but it always fails with one of these:
[81314.87292] i915 0000:00:02.0: [drm] *ERROR* Link Training Unsuccessful
Disappointing, but I haven’t needed HDMI output enough to devote serious time to debugging.
