This is a proof of concept for putting the CH375 USB Host Controller into HOST mode and using it to read a USB mouse on the Book 8088 computer (available on aliexpress.com).
This reads the mouse data and updates a cursor drawn in 80x25 text mode.
This is not a complete driver, it is just a proof of concept. It makes a lot of assumptions about the mouse and the environment. It is not robust and it is not complete. If you have a fancy mouse with more than 3 buttons, it will not work correctly.
This is based on code for doing similar things on the Arduino. https://github.com/Makeblock-official/Makeblock-Libraries/

Setup openwatcom and run the following:
$ wmakeCopy the resulting mouse.com file to the compact flash card, plug a basic usb mouse in, and run it on the Book 8088.
