          Hi,

           

          You can use CyU3PConnectState() API to force FX3 to enumerate as a HS device. Now, you need to connect a FS host to force FX3 into FS mode. wMaxPacketSize can be set to 8 bytes in the CyFxUSBFSConfigDscr[] for FS device.

          You can take USBBulkSourceSink example project as a reference.
