In general, Web pages and scripts that run in browsers are limited in what local system resources they can access. Direct access to hardware like USB devices has obvious security implications.

The only way I can think of to do this might be an <a href="http://www.microsoft.com/protect/terms/activex.aspx" rel="nofollow noreferrer">ActiveX control</a> (IE only, I think) or some other kind of browser plugin.

blocks|key|5781718|text|一种可能性是在USB设备中构建USB服务器。为该设备提供互联网访问，并使其在通过usb设备服务的网页控制的过程中下载其自己的固件。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5781719|请注意，我不知道这是否真的可能，只是觉得我应该用这种不同的方式来看待这个问题。|5781720|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

One possibility is building a webserver into the USB device. Give the device internet access, and get it to download its own firmware in a process controlled through the webpage that the usb device serves. 

Note that I have no idea if this is actually possible, just thought I'd throw in this different way of looking at the problem.

blocks|key|5781610|text|我能想象到的唯一方法就是通过JAVA|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|5781611|编辑:看起来也有一种ActiveX的方式可以做到这一点，尽管ActiveX只有Internet+Explorer，这限制了它的可用性。|5781612|entityMap|0|LINK|mutability|MUTABLE|url|http://www.ibm.com/developerworks/linux/library/j-usb.html|1|http://social.msdn.microsoft.com/Forums/en/iewebdevelopment/thread/e613f898-a18a-47e7-81bc-5a959ec2db06^0|E|4|0|0|A|7|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]]]

The only way I can possibly imagine doing this is through <a href="http://www.ibm.com/developerworks/linux/library/j-usb.html" rel="nofollow noreferrer">JAVA</a>

EDIT: Looks like there might be an <a href="http://social.msdn.microsoft.com/Forums/en/iewebdevelopment/thread/e613f898-a18a-47e7-81bc-5a959ec2db06" rel="nofollow noreferrer">ActiveX</a> way to do this as well, though ActiveX is Internet Explorer only, which limits it's usability.

blocks|key|3668237|text|可以创建一个ActiveX/.NETcontrol/Java小程序来完成此任务。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3668238|授予这个东西访问本地设备的权限将需要特定的安全设置，该设置可以自动进行，但在任何情况下都需要一些用户同意/交互|3668239|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

It is possible to create an ActiveX/.NETcontrol/Java Applet that will do it.

Granting the rights to this thing to access local devices will require certain security setup which can be automated, but in any case will require some user consent/interaction

I see here 2 ways:

<ol>
<li>ActiveX control

The problem is that the user should first download and install the
ActiveX from an Internet web server or from a local file</li>
<li>USB Device driver + DHCP Server + Web server embedded in the
device

Your USB device, once plugged, should present itself as a "Virtual
Ethernet Interface" in order for Windows to add the driver to the
list of the Internet Connections.

The Device should have also a DHCP server in order to give Windows
an IP address. Beware of the fact

The USB Device should also have an HTTP server.

At the end of this process, Windows will have 2 IP addresses.

Now you have to figure out how to have IE point to the index.html
file of the device.</li>
<li>Buy/Find a commercial software

You are not the first guy on this planet that has similar
requirements.</li>
</ol>

I'm wondering if there is a way to create an asp.net webpage that will connect a visitors USB device to an application on the windows bases server? This way we avoid having to install a software on the visitors computer to control a USB device update that they purchase form us.

All they have to do is visit our update page, plug their deivce to the USB, and have our site update the usb hardware.

Possible? or am I dreaming? :)

i found software like: USB over IP, and few others. But not show ure its possible to create a C# or vb.net based ASP.net page to control the visitors USB device.

Please advise.

control a users USB device via a webpage? Possible?

我想知道是否有一种方法可以创建一个asp.net网页，将访问者USB设备连接到windows base服务器上的应用程序？这样，我们就不必在访客的计算机上安装软件来控制他们从我们这里购买的USB设备更新。他们所要做的就是访问我们的更新页面，将他们的设备插入USB，然后让我们的网站更新usb硬件。有可能吗？还是我在做梦？:)我找到了像这样的软件: USB over IP，还有一些其他的软件。但不能保
