The ByteBlaster (parallel dongle with the same JTAG pinout) also does not have a TRST output. Some Altera FPGA devices simply do not have a TRST pin [1 note (6)], and as far as I know the JTAG state machine can emulate a TRST from any state in a bounded number of transitions (7 clocks I think it was).
The USB-Blaster does have two unused outputs, which are used in Altera's Active Serial programming mode, but any assignment of TRST and SRST between them would be arbitrary and not necessarily correspond to any particular board. How about two driver commands which specify the function of the two outputs, as unused, TRST or SRST?
