Can't read data from Honeywell Scanner

[tresf]

Edit: The solution is to provide a usagePage parameter. This is an API change... (2.0.6 and greater only)

var device = {
   vendorId: '0x0c2e',
   productId: '0x0b87',
   usagePage: '0x008c', //filter out 0xff8c
   readSize: 61,
   interval: 10, //ms

Before

qz.hid.claimDevice(device.vendorId, device.productId);

After

qz.hid.claimDevice(device);

We found a problem while working on #286 with the way Honeywell scanners work with QZ Tray...

• Honeywell installs two USB devices with the same VID / PID.
• QZ Tray grabs the first device with may NOT be the HID device.
• QZ Tray can never read data from the Honeywell barcode scanner.

A second feature will be added which allows querying on UsagePage parameter from the Honeywell scanner.

• -116 Incorrect USB device
• 140 The HID device, the one we want

Tested on:

• Windows - Works using PureJavaHIDAPI
• MacOS - Works using HID4Java
• Linux - Broken

We've decided to use usagePage for identifying the endpoint of the scanner, but there is a slight disparity on Mac...

• 4294967180 Incorrect USB device ⚠️
• 140 The HID device, the one we want

HID4Java appears to be returning a Long instead of an Integer. We could add long support to the library but the disparity could cause differences between API calls on Mac and Windows which is never desired. This seems like it may be a bug with the way HID4Java returns the usagePage.

Edit: Another option is to use a bitwise mask to see if the usagePage matches.

Turns out casting 4294967180 to short will make it -116. Implemented via 8eda5b5.

Closed via #289.
