hello everyone
Hello to everyone,
I have a project where I need to save data on a usb disk and communicate with the computer. I designed a circuit with a type A connector on the usb fs (a11 a12) line and a type b connector on the usb hs (b14 b15) line.
usb fs line works in msc mode. I can write data to usb disk. but I could not run the usb hs line in cdc mode. I made a cdc example from usb fs line before. Anyone have any idea why the usb hs line is not working?
I'm using cubemx 6.0.1 and STM32Cube_FW_F4_V1.25.1.
I saw something like this while debugging. I did not set the usb to high speed operation. I seem to have connection with the problem.
