tacva Posted March 22, 2015 Share Posted March 22, 2015 HI all, from yesterday i'm tring to connect my new amplifi 150 to my Win7 64 laptop, to upgrade the firmware, but no luck. I receive the message of unknown device, (USB device not recognized). I connected the amplifi after the utility request during installation, of course. I tried to uninstal drivers and software and restart the PC, and reinstall. I tried also to update the driver with the "l6AmplifiNA.inf" file but the system says thet ther is not an available driver or the driver is not designed for a 64bit machine. What is wrong? I have not other PC, just mac but ther is no utility for osx. Any suggestions? Quote Link to comment Share on other sites More sharing options...
Triryche Posted March 23, 2015 Share Posted March 23, 2015 Just for clarification, you have installed the USB driver before attemptong the Utility? Do you have access to an iOS7 or 8 device? Quote Link to comment Share on other sites More sharing options...
