Can I access USB HID device via a Chrome App?

Question

I have a simple little dongle I want to debug by sending/receiving basic USB messages. It enumerates as an HID device (like an additional mouse), but am worried that I won't have access to it. I forgot the hardware and can't test with it for a couple days.

Is it a futile effort to continue building a chrome extension to test it?

Chrome App, USB documentation: https://developer.chrome.com/apps/app_usb Getting-started example: https://github.com/GoogleChrome/chrome-app-samples/tree/master/usb/knob

Google Chrome now proposes a USB HID API. Have a look at the API: https://developer.chrome.com/apps/hid

The API is still defined as experimental at the time of this message. But it is functional. I have just written a tutorial to explain how to use this API.
