Hi,

I have an RFID Reader and need to pull the RFID Unique ID from it.  I installed the driver and open the device.  I ran the example to pull the bus and other device information.  However, I am getting an error when trying to do a read from the device.  The output is below:

Usb_Bus bus-0
        Usb_Device \\.\libusb0-0001--0x067b-0x2303
                Usb_Device_Descriptor idVendor: 0x67b, idProduct: 0x2303
                Usb_Config_Descriptor bNumInterfaces: 0x1
                        Usb_Interface num_altsetting: 0x1
                                Usb_Interface_Descriptor bNumEndpoints: 0x3
                                        Usb_Endpoint_Descriptor bEndpointAddress: 0x81
                                        Usb_Endpoint_Descriptor bEndpointAddress: 0x2
                                        Usb_Endpoint_Descriptor bEndpointAddress: 0x83
ch.ntb.usb.USBException: USB device with idVendor: 0x67b, idProduct: 0x2303, busName: null, filename: null not found on USB

Any pointers are suggestions would be greatly appreciated. 

Thanks
Andy
