Hello,
I have some problem to USB communication. Hello, I have some problem to USB communication. when I tested USB communication device class, my computer was shutdown and reboot. so I checked the dump memory, but I don't know what this means. I think this is not the hardware issue or PC application. because I replace the PC, target Boards(STM32F4Discovery) even replace the MCU(STM32F103). but when I uses 8051 and UART bridge, it works well. so I suspects the firmware or usb driver. please review my problem. -------------------------------------------------------------------------------------------------------------- Test Environment Target Board: STM32F4Discovery
