The difference between the "JAM STAPL player" and "quartus_jli" ?

Hi all,

I want to find out a method to readback the USERCODE of the FPGA via the JTAG download cable (USB-Blaster) on my PC side.

1. ​quartus_jli (Nios II Command Shell): I can readback the USERCODE.
2. JAM STAPL player (Use Command Window): I cannot readback the USERCODE, it show the error message "I/O error: cannot open device \\. \ALTLPT1. Check port number and device driver installation."

I had found the following topic about the error message (https://www.intel.com/content/www/us/en/programmable/support/support-resources/knowledge-base/solutions/rd03311999_546.html), it seems that the ALTPLT1 is the driver 's name of the ByteBlaster cable.

If I want to readback the information by using the JAM STAPL player, do I must use the Byteblaster cable instead of the USB-blaster cable ?

Thanks a lot.
