After figuring out the K830 wasn't really usable for me my brother gave me a generic bluetooth keyboard with touchpad that he wasn't using which paired fine through the Oculus app bluetooth gamepad option.

Keyboard and touchpad works overall however some things I noticed

• had to enabe numlock after initial pairing (didn't have to do this after forgetting and re-pairing afterwards)
• win key does nothing
• some key combinations don't seem to work (alt+tab in general, ctrl+shift+n does not bring up incognito tab in chrome)

Unfortunately he doesn't recall where he got it from and there's no markings on it whatsover to identify a brand or model number. I found this 1byone bluetooth keyboard on Amazon that matches the look and feel, key layout, trackpad/buttons, stainless steel backing, battery compartment almost one for one. Only difference based on the images is the 1byone logo, labels on some of the keys. Possibly just a re-branded version of the same keyboard. If I find the original device's listing on amazon (and its still available) will update this comment.

EDIT: Here is the original item which looks to be no longer available.
