Steps to reproduce the problem:
1. navigator.usb.requestDevice({ filters: [] })
2. all HID device will not show any more, also non keyboard, mouse, touchpad devices

What is the expected behavior?
Only HID devices which have a standard driver should be filtered out. 

There are a lot of special devices for the human interface which comply with the USB Device Class Definition
for HID Devices which do NOT have such a standard driver. 

Example: We have here a lot of Motorola / Symbol / Zebra barcode scanners (DS6708). They can be set into different modes which comes up with different pids

- USB Keyboard HID: "productId": 4608 
   USBAlternateInterface {alternateSetting: 0, interfaceClass: 3, interfaceSubclass:1, interfaceProtocol: 1, interfaceName: null}  
   USBEndpoint {endpointNumber: 1, direction: "in", type: "interrupt", packetSize: 8}

- IBM Table-Top USB: "productId": 5120 
   USBAlternateInterface {alternateSetting: 0, interfaceClass: 3, interfaceSubclass: 0, interfaceProtocol: 0, interfaceName: null}
   USBEndpoint {endpointNumber: 2, direction: "in", type: "interrupt", packetSize: 64}

- IBM Hand-Held USB: "productId": 4864
   USBAlternateInterface {alternateSetting: 0, interfaceClass: 3, interfaceSubclass: 0, interfaceProtocol: 0, interfaceName: null}
   USBEndpoint {endpointNumber: 2, direction: "in", type: "interrupt", packetSize: 64}

- Simple COM Port Emulation: "productId": 1536
   USBAlternateInterface {alternateSetting: 0, interfaceClass: 3, interfaceSubclass: 1, interfaceProtocol: 1, interfaceName: null}
   USBEndpoint {endpointNumber: 2, direction: "in", type: "interrupt", packetSize: 64}

Only in the first mode the scanner will be used with the system keyboard driver. But a keyboard driver is not able to handle all cases. I.e scanning post stamp barcodes, which hold binary data can not be done by handling keyevents. But also on ASCII data handling keyevents is insecure because in blink the is no way to differ between devices (real keyboard and scanner).

All the other modes work only with special native drivers which have to be installed first and are not available for all OSs. Also these drivers does not help on blink because they have their own non standard interfaces, which can not be accessed by blink APIs.

Reilly, in your posting https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/LZXocaeCwDw you substantiate this change with "... most USB devices fall into one of a number of standardized device classes for which there are already high-level APIs provided by the Web Platform". 
But there is no navigator.hid API. And chrome.hid was only for chrome apps, which were dropped. So which API can we use instead?

What went wrong?
All non standard HID device are filtered out

Did this work before? Yes 

Does this work in other browsers? N/A

Chrome version: 66.0.3359.181We  Channel: n/a
OS Version: OS X 10.9.5
Flash Version: Shockwave Flash 30.0 r0

Up to now this is only a problem on windows version. MacOS and Ubuntu still work, also on canary builds. Will this stay like it is?
