I can confirm that the USB Blaster works correctly on Windows 7 64-bit (didn't test on other OS type/version) using the driver supplied with Quartus 11.1 sp1 (and earlier), but doesn't anymore with Q11.1 sp2's driver. When comparing the two, apparently version 2.08.14 (03/18/2011) of FTDI's original driver is now used instead of 2.04.16 (02/17/2009).

Note: I'm still using Quartus 11.1 sp2 application, but with the 11.1 sp1 USB Blaster driver!
