device type=3

vid pid type=2

in the ftdi deivce re-program what is device type 3 and vid pid type 2.. actually in device type it shows different ftdi devices and vid pid type- 3 options 1. default 2. only pid 3. vid and pid..

so please tell which to select..

one more question: i tried to change these settings, it is getting detected and programmed as usb blaster, but i am not able to program/ configure through it..

error in quartus: unable to establish jtag chain (do you think tck speed is the issue?)

thanks,

mahesh
