Super ContributorHi,
May I know if you purchased the USB Blaster and the Cyclone IV from our authorized distributors? If no, we cannot guarantee the functionality of the devices.

Super ContributorUSB Blaster clones are known not to work with recent drivers. See previous forum discussions, e.g. https://community.intel.com/t5/Intel-FPGA-Software-Installation/USB-Blaster-Not-Found-In-Quartus-Prime/m-p/1571621
Problem is most likely caused by newer FTDI drivers (CDM version >= 2.11) that actively block non-FTDI devices mimicking FTDI.
