Using Java to communicate to a USB device from browser

Hi Experts,
We have a ASPNET web application and now we have a new request: the client wants to communicate with their USB device using our application. They plug the device into their PCs, open a page of our web application and the page will communicate with the device to get some input. Of course the device must already have proper driver. Comunication here means reading some input from the device.

Someone said that we can use JAVA to do this. So I'd like to get more information about it. Can someone give me a guide or a link which tells me how to do?
Thank you for reading.

Hi,
Sorry for my late response. I have learned the links you gave me. I found out that the javax.usb library only works on Linux. It is not good for me :(
However, it seems that the library aims to help us access usb devices directly regardingless drivers, doesn't it? What about if a driver is ready? Is it easier to access it?
Thank for you help :)

Whether via an applet, or a JavaWebStart application, the simplest approach is to reach into the host OS' filesystem. For example on UNIX/Linux/OSX hosts, you would go to the mount points of drives, and simply locate the mounted USB drive there. For Windows, you'd need to deal with its drive letters, etc..

Personally, I would try to avoid USB-specific Java libraries at all costs, and try to create a solution based on the above approach. Sticking to standard JRE APIs is sticking to tried-and-tested, supported classes.

We are waiting for more input from our clients. Although your posts don't give me what I was looking for, which might not really exist, they are still good hints for me. Thank you all :)
