Here is the sourcecode of the Visual Basic Program which i used to transfer Data to the Device

Here is the Logoutput of USB Snoopy when transfering data to the device using the VB Program

Here is the output of the USB-Robot

I tried to send data to the device using the usb-robot-slave which uses the libusb.

doing bus scan for:
        idVendor 0x925
        idProduct 0x1234
found bus 001

I tried to transfer anything to the device using this Hid Program, it says that everything was successfully sent, but there is nothing displayed on the debugger. Shouldn�t the Firmware check the byte in Ep0?
