I just installed Quartus II 11.1 sp2 web edition and I do not see the USB Blaster on the Altera Cyclone III starter board in the Hardware Setup tab of the Programmer application. This is on a 64-bit Windows 7 installation. I have used older versions of Quartus II web edition on a different 64-bit Windows 7 machine and it worked fine. I see the USB Blaster in Device Manager and it says the device is working normally. I also see the Altera JTAG Server service in the Services list and it shows "Started". What am I missing? What has changed?
