Topic: USB Blaster library not working (Read 505 times) previous topic - next topic


i downloaded the usb blaster library and uploaded the included example sketch to my vidor.
The onboard led started to blink so it seems to work, but when i open quartus in can not select it as a programming device. Am i doing anything wrong?


Do you find "Atera USB-Blaster" under usb or unknown devices?

When opening Quartus programmer. Opening Hardware setup. Is there any device listed in available hardware items.
But here you need to select hardware what you want to use from dropdown list.



Thats the problem:

In the device manager of windows it is listed as Arduino MKR Vidor 4000.
But in does not show up in the quartus programmer dropdown.

Device manager should say under USB devices "Altera USB-Blaster" and there sould be no "...Vidor 4000" under Ports

Do you have 1.0.0 USBBlaster library version?

Little stupid question. Have you updated Vidor bootloader?


yes i have version 1.0.0 and my bootloader is up to date.

My usbblaster sketch give these

Device description
Altera USB-Blaster

Hardware Ids

Code: [Select]

#include "Blaster.h"

static bool activityLed = true;

extern void enableFpgaClock();

void setup() {
  // also start the 48MHz clock feed for the FPGA, in case we need to run the bitstream and need this clock

void loop() {


you just loaded the code to the vidor and it worked with quartus right away?

Did you do anything special in quartus to let it show up?

yes. One thing was I was also using DE0-Nano before getting Vidor.

But after loading code to vidor it detects as "Altera USB-Blaster" under unknown devices or usb devices.

In my case I have to double tap reset to go bootloader mode if I wan't to load another sketch after using USB-Blaster.

Added screenshot from device in device manager that should appear after loading USB-Blaster sketch

The same kind of problem has reported before.

I hope this article may help you:

Then in my case I had already right drivers loaded becuase I have used DE0-Nano. It uses same VID/PID.
