I found out that my cable was faulty and replaced it now. Now i am to see USB-BLASTER[USB-0] when i run jtagconfig in command prompt. Thanks for your suggestions! Re: Error when scanning hardware - Server error No there are no multiple download cables. i have tried on different PC as well, still the same error. The usb blaster has only power light lit up, there no light on ACT. Is it the problem? Re: Error when scanning hardware - Server error Hello, Thanks for the reply. I am using Windows 11 and Quartus Prime Lite 24.1 version. I tried with version 18.1 as well. I haven't tried using a different blaster cable yet. Currently, I am using Altera USB Blaster Rev. C. Yes, that is the only error the terminal shows. Is there any way to resolve this? I have to try with new blaster ? Error when scanning hardware - Server error I want to communicate my MCVEVP SoC cyclone v FPGA with host PC. So i am using JTAG USB BLASTER cable to establish communication. I am getting the error "Error when scanning hardware - Server error" when i run jtagconfig in my command prompt. I am able to find altera usb-blaster listed in my device manager. I tried to update drivers, uninstall and install them again, reinstall quartus prime, checked all the connections, nothing seems to be working. could anybody please help me with this?
