I had the same problem with my usb blaster under q11.1sp2.

OS: Windows 7 / 64, Service Pack 1.

Quratus II : 11.1sp2_259_quartus_free_windows

I solved the problem in the following way.

- i unistalled the usb blaster driver (device manager),

- than i copied the driver folder of a q11.0 WE installation from my laptop in the driver folder of my q11.1sp2 on my pc,

- (i think it is also possible to copy the folder to a different destination)

- after this i reinstalled the usb blaster driver manually (see Dr.Lightnings last post),

- than i started q11.2 and the usb blaster is selectable in the programmer setup window.
