Hi everybody,

I have used STM32 HAL libraries to communicate with PC using USB CDC. I want to send a huge amount of data to PC and so, the communication speed is very important to me. However I could get very low speed from the usb cdc.

I want to the maximum speed of the usb cdc using the HAL library? and which class of the usb devices is the best for my purpose?

I appreciate any attention
