💀 BUGS 💀

real talk, bestie, there are some caveats:

• Does not support all of UVC spec. 😭
• Only supports the one streaming input interface.
• Does not support the interrupt endpoint for some controls.
• Exports the Video4Linux2 API via video(9), and V4L2 lacks support for some UVC features such as still images. 💀
