If you attach a USB laser scanner, which is faster to operate than the built in scanner, you have to disable it as a USB keyboard in order to be able to use the soft keyboard. Can your build of Android just make this a default, so that merchants don't have to go digging for this setting every time they either attach the scanner or the device reboots?
Here's some related links: http://stackoverflow.com/questions/92... http://stackoverflow.com/questions/81...
To elaborate, newer (yet to be released in most cases) Clover ROMs will prompt the user immediately when an HID USB device is connected. The prompt asks the user if this is a USB keyboard, or not. If the user answers no, it will automatically toggle that values that's buried in settings to not hide the on-screen keyboard when this device is connected. It will remember this across reboots.
If it's a known, supported USB barcode scanner, no prompt is shown. In this case we interface with the scanner at a lower level and it's not treated as a USB HID keyboard (this behavior hasn't changed).
The behavior I described is not customizable. The merchant will always see the dialog unless they choose "don't show again for this device", from the dialog. This ROM is rolling out now and should be available to everyone soon on Mini and Mobile. Station will be a lot longer.
Thanks for the suggestion. We are considering making this change.
