Hi guys,

I recently updated and rebuilt my computer and its running ubuntu 12.04 lts. I loaded all the programs for the serial to USB,nerdkit,avr files. But when I type "make" it says /dev/ttyUSB0: permission denied. It worked fine on my old machine: Pentium 3 xubuntu 11.04.

I see the prolific to usb driver when I type lsusb in terminal. Any Recomendatoins?

Thanks, Dan

Hi Dan,

That's quite odd. I am having no problems with the device on 12.04. Have you tried doing a "sudo make". Its a bit weird to give make sudo privilages, but I'm curious if it will work.

I was able to get it to work yesterday! Thankfully. I have no idea why 12.04 is like that. 11.04 seemed to work fine.
