Trackball Button Fixed (22 September 2022)

I just fixed my Logitech TrackMan Marble’s left button.

The button developed an issue where a single-click would register as a double-click, and click-and-drag was unreliable. I opened the trackball, determined the model number of the button to be D2FC-F-7N, and obtained replacement buttons of that type.

I removed the old button and then soldered in the new one. A quick check with xev confirmed that the new button worked.

The left button is now reliable again.
