I've recently been scouring Haiku's sources, and according to the driver's sources and FreeBSD man pages, have been adding supported devices into the hardware database here - there are now over 650 entries! I've completely gone through the bluetooth, video and network drivers.

In the end I got a little lazy, which is why you see more wireless network devices than wired in the database. Reason being, for most of the FreeBSD ported drivers, I added the supported devices from the man pages into the listing's description.... i.e:

Intel Pro/1000 Gigabit Ethernet Driver.

Or listings like this one that contain an additional 23 supported hardware devices under one listing:

Sound Blaster 16

Hopefully this will demystify Haiku's hardware support a little, and bring an easy way to comment on, vote on, add attachments (i.e syslogs, drivers) and descriptions to hardware, and search if your hardware (or soon to acquire hardware), is supported. :) You can also use search to search devices that aren't supported, and search device and vendor IDs.

I plan to tackle the audio drivers at some point in the near future.
