Additionally, as I am beginning development with the MAX V CPLD, could you suggest the type of debugger I should use to avoid potential issues down the line? Replies: Re: USB BLASTER is showing in device manager but not getting detected in hardware setup of Quartus prime Hi, these USB Blaster clones are known not to work with recent Windows 10 USB Blaster drivers. As far as I know, this is no intentional restriction created by Intel but due to the fact that the original FTDI driver used as part of the driver stack is blocking counterfeit and also emulated FTDI chips. There are solutions suggested on the net, e.g. using Windows 7 drivers. Search for USB Blaster Clone. I prefer Terasic USB Blaster or Arrow Blaster as economic solution.

I have tested one USB blaster, here is the following link. https://www.flyrobo.in/usb-blaster-altera-cpld-fpga-programmer?tracking=ads&tracking=4a9a9a&gad_source=1&gclid=Cj0KCQiAst67BhCEARIsAKKdWOnS1Ic9tx34q9Gp_j0umB9ksllTyBn5EwmBuYc-piXsLOBYUqtIoxQaAj4IEALw_wcB 2. The USB blaster is getting detected in Device manager, I have given a proper path. But its not getting detected in hardware set up in Quartus Prime Lite 22.1 std edition. 3. I have tried many times to install and uninstall the driver, its getting detected with some of the driver but not showing up in Quartus prime, even I tried with the Quartus II programmer but its not getting detected. Am I missing some small details to operate it with EPM240T100C5N CPLD? Regards and Thanks Arpan Replies: Re: USB BLASTER is showing in device manager but not getting detected in hardware setup of Quartus prime Hi, How many USB blaster has you tested and how many are working? Does the broken USB blaster ever been detected before? Have customer try to uninstall and reinstall the USB blaster driver? Regards, Aiman
