I checked my old Trust 15862 mouse: Identifies as PixArt Imaging mouse (093a:2510). HID_QUIRK_ALWAYS_POLL is set for it since longer time. The clicking sound is too loud. So I don't use it. Seems to be a good chance to take it apart and check the PixArt chip inside.

There is a screw beneath the round "QC PASS" sticker.

So there is a PAN3511 inside. PAN3511DK is visible on the PixArt chip. The PCB seems to come from PixArt as well.

The red mouse wheel encoder is from TTC, button switches as well.

I accidentally broke the top left plastic latch while opening the device. Stretch the top casing by pulling it into outside direction at that location to avoid that.
