Hi,

May I know if this issue is also happening if you are not using VM? I would like to isolate to see what is actually happening.

May I know whenever you use VM, you are seeing hanging issue detecting the blaster or the blaster is detected but not FPGA device?

No. jtagconfig is working properly when I connect it to my hhost OS. (Windows 10 with Quartus 17.1). But I didn;t check it for same environment as in VM. Since When I create a new VM with Ubuntu 14.04 and Quartus 15 and call jtagconfig works fine means it's not a issue with VM right?

What's happening is when I first connect the FPGA into VM the device is detected with revision no 1034. Then when I called jtagconfig device is detected again with different revision no 0111. and in VM it indicates that the device is attached. (like in this screenshot).
