Hello everyone, I've recently bought an NFB-11 (2015). At first I followed all the instructions regarding driver installation etc. but my device was not being recognized by my system (Windows 7 64bit). I kept on plugging and unplugging the USB cable, install/reinstall the driver until suddenly my device was finally recognized. I happened to enjoy the product for a few hours, then I turned the Amp off, then my laptop off. The next day, my device was again not being recognized by Windows. I reinstalled the driver, tried to look for loose connections, tried different ports, tried different cables, even tried a different PC but to no avail. I'm getting frustrated already, any clue why my device isn't being recognized by my computer? Thank you very much!
