Hi, Just managed to test this: http://www.seeedstudio.com/depot/dsjtag-2-in-1-usb-jtag-cable-for-fpgacpld-= p-1040.html?cPath=3D174 DSJTAG - 2 in 1 USB JTAG cable for FPGA/CPLD It claims to support Xilinx Impact and Altera IDEs. I have tested Xilinx 13= ..3 Impact and it works well with the programmer. Did pull out the cable from the target and push it in again without restart= ing the PC or Impact software :) Work okay on that side. Programming works well too. Did not TRY a big JED file but it is fast for s= maller ones....
