There is now a product, the need to implement a USB keyboard mouse and UKey functions, specific as follows:
Interface connecting the USB port of PC host USB - 1
USB - 2 connect USB keyboard peripherals, may meet UKey equipment, indirect and PC communicate via USB - 1
USB - 3 connect USB mouse peripherals, may meet UKey equipment, indirect and PC communicate via USB - 1
The three interfaces have USB2.0 high-speed communication ability,
All the three USB ports by a MCU control, MCU to get data from mouse and keyboard interface, interface real-time sent to PC through USB - 1,
The question now is on USBKEY, when USB - 2, USB - 3 access after the UKEY equipment, I not only need and MCU UKEY communication, and PC communication, let the UKEY and host indirect communication, and now, the UKEY is not our development, is a customer of a product, the UKEY this equipment is not very understand, don't know how to write the UKEY MCU firmware?

Not using a USB Hub?CodePudding user response:
Cannot use the HUB, because the MCU to deal with the keyboard key code and data, the coordinates of the cursor with the additional function ~
