Hello,
Has anyone here had any success getting the USB Host Shield (https://www.sparkfun.com/products/9947) to work with a barcode scanner? I'm trying my best, using the code examples on this website http://www.circuitsathome.com/mcu/connecting-barcode-scanner-arduino-usb-host-shield but to no avail. Anybody here have any tips? Thanks.
Well Sir, you set your self to a amazing task but noting is impossible
First step will be to run the sketch name USB_desc in the example folder of the libraries USBHostshield20 that you can find here:
Then your gonna have to compare the descriptor to the one you reference here:
http://www.circuitsathome.com/mcu/connecting-barcode-scanner-arduino-usb-host-shield
to see if they are compatible.
And if they are not, well let's see if those bar scanner still act like if they are Keyboard. So basicaly try to run the USBHIDBootKbd example that you can find in the folder
.\libraries\USBHostShield20\examples\HID\USBHIDBootKbd
If your lucky you wont have to build a new libraries, If you are not, well you got lot of work ahead of you. Give me news about it.
Then your gonna have to compare the descriptor to the one you reference here:

There is no information about scanners on that site
