I am working on a project where I would like to access data that's been stored on a device which is recognised as a usb HID class and I want to create a firefox plugin that access these data when needed.

  1. what is the best way of aproaching this ? I know first of all I have to deal with the USB HID protocol and then I was thinking of making NPAPI cross browser plugin using QT-browser plugin.

  2. Is there any better alternative. And please give a good solution for linking usb HID protocol and firefox plugin as I am new to this.

thank you

  • Why going so low-level? what kind of usb device is this that you have to access on a level that is usually handled by device drivers? – M.J. Saedy Apr 11 '14 at 17:17
  • Its a device in which there is smartcard storing info such as passwords and all – vasthav Apr 13 '14 at 09:05
  • For anyone looking at this, Chrome provide chrome.usb and chrome.hid API to handle this, and Firefox started looking at integrating HIDAPI from signal11 see here: https://bugzilla.mozilla.org/show_bug.cgi?id=1198330 – mspisars Jun 14 '16 at 21:51
