-# ms912x driver for Linux
-
-Linux kernel driver for MacroSilicon USB to VGA/HDMI adapter.
-
-There are two variants:
- - VID/PID is 534d:6021. Device is USB 2
- - VID/PID is 345f:9132. Device is USB 3
-
-For kernel 6.1 checkout branch kernel-6.1
-
-TODOs:
-
-- Detect connector type (VGA, HDMI, etc...)
-- More resolutions
-- Error handling
-- Is RGB to YUV conversion needed?
-

-Driver is written by analyzing wireshark captures of the device.
-
-## DKMS
-
-Run `sudo dkms install .`
