I have encountered the same problem.
The way I have resolved it in my Visual Studio C++ Console Application for Win32 was as follows:
1. I have obtained the number of Digilent devices by DmgrEnumDevices() API function.
2. If number of Digilent devices was 1 (the connected one) then I have obtained the device Info by DmgrGetDvc() API function called with first parameter equal to 0.
3. From obtained Digilent Device Information structure I have used the Device Name "szName" field to open the Device by the DmgrOpen() API function.
The rest of application was like in Tutorial.
Good luck.
Hi Attila, I want ask you to send me the firmware for the Cypress CY7C68013A stored on my Nexys2 board.
Currently cypress does not assert the USB-ON signal, which enables the power. Regards Radek from Poland
