Can anyone help me out why i am unable to power on a USB barcode scanner using beagle even when a phone is charging properly from the same usb port.
I have a BBB
Does the USB barcode scanner have a external power supply?
no there is no external supply. it’s just a plug-and-play device
I’ve been using a few barcode scanners lately without problem. See http://github.com/jadonk/beagle-tester under beagle-tester.rules to see 2 USB VID/PID pairs of barcode scanners I’ve been using. I’ve only tried 2 and both worked out of the box.
Barcode must use below 500ma in order to get energy from USB, maybe a bigger power supply on Beagle??
