Ubuntu 20.04 - Can't see USBasp

The device is visible in lsusb, but not in the Arduino IDE.

I can see my serial programmer in the Arduino IDE, but not my USBasp.

Any idea what's wrong?

The USBasp is a pure USB device. It does not produce a serial port. So it is not expected for you to see a port in the Arduino IDE's Tools > Port menu for the USBasp.

Are you able to use the USBasp with the Arduino IDE? If not, please post the full error output and we'll take a look.

Thanks for your reply. It seems I've forgotten how to use it.

Here it is on USB:

But I'm getting an error in the Arduino IDE

Error while burning bootloader.
avrdude: Warning: cannot open USB device: Permission denied
avrdude: error: could not find USB device with vid=0x16c0 pid=0x5dc vendor='www.fischl.de' product='USBasp'



Thanks. I found the problem after reading that helpful guide. You have to restart the Ubuntu OS (quite often Ubuntu requires no restart to use new software or make use of changes).
