I'm trying to connect a Fujitsu ScanSnap ix500 scanner and my MBA 2018 will not recognize the device. I have changed the USB to USBC adapter, and changed ports on the MBA. I have also switched out the Usb cord to the scanner. The scanner is not showing up as being connected to the laptop either. I have used this scanner previously and it was connected to my 2016 MB Pro without issues, with the same cables and adapter. I have another single sheet feed Fujitsu Scanner and it connects just fine. I restarted my MBA and still nothing is working. Is this an adapter issue? I've tried three different USB adapters that all work with other devices. Thanks in advance for your help and suggestions.
