Detecting and accessing a usb device from within a webbrowser -i.e using a plugin

Question

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.

I have done some

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. :-(
