7 years ago --- Quote Start --- Hi, Right click on "unknown device"->UPdate Driver Software->Browser to the Quartus installation directory ("C:\intelFPGA\17.0\quartus\drivers\usb-blaster")->click next. If it does not solve the problem try previous post by garypace. Or Reinstall the Quartus tool. Let me know if this has helped resolve the issue you are facing or if you need any further assistance. Best Regards, Anand Raj Shankar (This message was posted on behalf of Intel Corporation) --- Quote End --- Hi Anand- Thanks for replying. The connection does not show up as "unkown device". Instead it shows up as a fully configured "USB Serial Port (COM4)". Could this be a part of the problem? Windows does not change the driver after: UPdate Driver Software->Browser to the Quartus installation directory ("C:\intelFPGA\17.0\quartus\drivers\usb-blaster")->click next. Thanks, -J
