As titleI generate USB CDC with STM32CubeMX,and try to send data by using interrupt transfer end point 0x81I try to usb Bushound to receive data, but it could not revive any data from CDC interrupt IN.Is there any things that i should be modify?Exper...

If we want to implement USB to multi-interface at the same timesUSB to UART1~3USB to I2C1~3USB to SPI  USB to PWMUSB to SD cardWe use STM32F4 , USB 2.0 have 5 in / 5 out endpointsi think we could use USB mass storage protocol to implement USB to SDbu...

Hello everyoneIn datasheet, i only read following messageUSB OTG HS6 bidirectional endpoints12 host channels with periodic OUT supportDoes it mean that STM32F439 would support 12 OUT endpoints and 6 IN endpoints or?
