Description
You will get this error message when running a command line to program a device via the USB-Blaster™ programming cable as below:
quartus_pgm.exe -c Usb-Blaster -m jtag -o pv;"myfile"
This is because the bridge device is not being initialized before the configuration process starts. In order to workaround this problem, just add an "i" switch to the command line to set the "Initialize Bridge Device" option to ON.
The correct command line is as follows:
quartus_pgm.exe -c Usb-Blaster -m jtag -o ipv;"myfile"
