Ok I will try to add those categories as soon as possible, thanks

As a user of a graphics tablet that wasn't supported by released kernels when I bought it, I support this issue. Would "input devices" be an ok name for this? (Keyboards and touchpads are also known types of these devices. Touchpad support depends on the vendor, useful for me features are missing in the driver of one that I have.)

Not all of these devices are USB or Bluetooth (internal ones in laptops aren't), some data about them is provided by kernel input drivers.

Hi, here are new "candidates" for hardware in this category (i put them here in order to remain registered). Two integrated USB devices from the Dell Studio 1535 (PP33L) notebook:

How about Input devices as a category?

I agree to the creation of a category called "input devices" and .... with SteamOS in the news a lot this week , I thnk that users will want to know these Libre alternatives that exist.

One other option , is that input-controller would also work as a secondary suggestion, and , would look quite nice below 'host-controller' as a good tie in, although I do not know if this is technically accurate for game controllers, but looks good.

As I say, this issue is nearing a year old, and I would flair this post's importance as matter of urgency.
