When AN75779 example project is loaded onto FX3, it will enumerate as a UVC class device, as the USB descriptors are reported that way. In this case, FX3 will bind to the Microsoft UVC driver.
You can see 'FX3' under Imaging devices section of Device Manager.
When an example project such as SlaveFifo is loaded onto FX3, it will enumerate as a vendor class device and binds to the Cypress driver.
Control Center displays only the devices that are binded to Cypress driver.
OK,rghe,I see.Thank you very much.
I have a question about slavefifo example.My original data has some special feature.The first data period has 1024 byte data and The second data period has no data .The third data period has 1024 byte data and the fourth data period has no data,and the rest follows in the same regual pattern.Every data period has same time.When I add a control signal in FPGA,the fifo is work normal in FPGA by watching altera signaltap II,but the USB3014 cannot work in no data period, because the host software will stop data acquiration .Why the auto DMA cannot move data to usb endpoint automatically in no data period and lead to the FX3 fifo is full？So My fpga will not work if I add FX3 FIFO full flag signal .
