add input device

[kmjoye]

macOS 10.13.1, Acrobat Pro 11.0.23, when using File>Create>PDFfromScanner, the "Acrobat Scan" dialog shows a pop-up menu of scanners under the "Input" heading, but the list of available devices does not include the device I see in the macOS SystemPreferences/Printers&Scanners list.  I expect that I should be able to add an input device to my scanners list in AcrobatXI, but that is not as obvious as I'd think.  Any pointer much appreciated.  (my current workaround is to scan from the SystemPreferences dialog, then open resulting file from Acrobat...)

There could be multiple root cause for this issue like drivers problem, connectivity problem, compatibility issue, hardware issue or installation problem. Please try some troubleshoot option available in the link https://helpx.adobe.com/acrobat/kb/troubleshoot-scanner-issues-acrobat.html. If the issue still persist please let us know.

Thanks.
