Is it possible through a plugin - activeX, Java or Flex to write a brower plugin that is able to detect an read a data stream from a USB device channel.

Answer 1

I believe it can at least be done with Flash. I use an EasyBloom, a USB gardening diagnostic device. The flash app on their website access the device on my local laptop.

Sadly, I have no idea how they do it since I don't do Flash. :-(

Answer 2

It's considered a security risk to expose local resources and the sandbox environments for the different plugins should deny access to these resources.

So I would say that the answer to your question is a No.

Answer 3

Flash can do it. Your users should allow it first. Check this link: Flash documentation for Security
