USB-Blaster Driver for Linux

Quartus^® II software uses the built-in USB drivers (usbfs) on RedHat Linux to access the USB-Blaster^TM download cable. By default, root is the only user allowed to use usbfs. You must change the permissions on the ports before you can use the USB-Blaster download cable to program devices with Quartus II software.

You must have system administration (root) privileges to configure the USB-Blaster download cable drivers.

Select the appropriate RedHat Linux Enterprise version to change the port permission.
