On a brand new PC (Win10 x64 32G just installed Q17.0. Plugged in the USB-Blaster. Loaded a project, opened the programmer and the USB-Blaster was no where to be found. Found it in the device manager with a problem. No known reason for the problem. Tried updating the driver by selected the Blaster directories under Drivers - didn't work. Came to think of it; had the same problem last time I played with Q16 on another machine with a DE0-Nano-SOC. Found that if you chose just the Drivers directory and not the Blaster directory it finds the driver needed and pops up in the programmer. Why Altera/Intel has this been a problem for so many years and how many years more are we going to wait for it just to work when it's plugged in?
