hi, i'm using stm32f4 mcu for lots of periph.
the usb communication (2.0 high speed) of my project has a problem
there is no problem between my desktop pc and mcu board
but, my mcu board usb does not operate properly in my laptop or others desktop pc
when i was debugging this, i found that usb character (1byte only) was received at the CDC_Received_HS(---) function
this function argument is received string length and Rx buffer pointer
i don't understand why this happens.
i also has installed virtual comport driver on my pc and desktop pc (OS is window 10 pro)
anyone help
thanks.
