Can't connect to JTAG on EP4CE6 Mini Board

I'm trying to use this board but failing to connect to JTAG on it, either via the command line jtagconfig or via Quartus. https://www.ebay.com/itm/Altera-EP4CE6E22C8N-Mini-FPGA-Board-Cyclone-IV-/1120...

The USB port is not meant for programming the FPGA. Its meant for USB to UART PC communications when developing NIOS-II based applications or any other applications that need PC serial communications.

The board uses the standard 9-pin JTAG programming interface. You need to use the standard Altera Byte-Blaster download cable to program this board/device via JTAG interface.

The website clearly states the following:

JTAG configuration interface

So you need to buy the Altera Byte-blaster JTAG download cable and use it. Only the later boards feature on-board USB-Blaster and use the USB Blaster cable.
