I have implemented the code contained in the SDL documentation for UsbDiscoverer.
However the UsbDiscoveryHandler.discoveryFinished() fires without ever finding the attached USB printer (neither UsbDiscoveryHandler.foundPrinter or discoveryError fire)
I am connected to a iMZ220 and want to provide an option to use USB rather then Bluetooth.
I have added to USB_PERMISSUION to my manifest.
I am currently connecting the Android device and the printer via a USB hub pending delivery of a USM mini to micro cable which may be an issue.
Any ideas why the discovery fails to find the printer ?

Hi Graham,
You do need to use a USB "On The Go" cable to connect the Android to the printer. Other than that, there is a lot of setup needed to do USB discovery. If you are following the code in the Android SDK documentation for using USB, then I would say it's likely your cable.
Hope this helps,
Robin
