experiment with USB & HID devices

[s-light]

get access to native connected usb devices.
HID devices would be ok for now..

according to stackoverflow - Serial or HID (usb) Communication in iOS (iPhone/iPad)
wired connections to iOS devices are only possible when the device is registerd in the official Apple MFi Program

implement & test

• test HID
  • node-hid
  • [?] cordova-plugin-hid-usb
• test USB
  • not usable for our HID device. (see details)
  • WebUSB
  • Node WebUSB
  • electron-usb
• [?] find / create cross platform WebUSB or HID wrapper
  (with fallback & dummy options)
• [?] create quasar / vue component / service

research WebUSB

Its already implemented in Chrome & Opera.
so should be a good thing to use...

• introduction blog post
• electron: Device chooser for WebUSB
  → links to webusb node package as fallback
• electron-usb
• MDN - USB
• cordova
  • cordova-plugin-chrome-apps-usb
  • @guaiguaiob/cordova-plugin-chrome-apps-usb

[s-light]

research HID

• node-hid (github)
  example
• node-hid-async
• hideous hotplug
• cordova-plugin-hid-usb

Results of WebUSB research

currently it is not possible to use HID devices from the browser.
WebUSB can not claim HID devices - as they are handled by another OS driver...
in the future eventually WebHID could be the solution to this..

  That is correct. On all platforms a device advertising the HID protocol will be claimed by the system HID driver and should not be claimed by a site using the WebUSB API.

  If you want to connect to an HID interface you will need to modify the device so that the interface is no longer marked as HID.
