网站上的USB设备

usb web-services php

是否可以使用我直接在网站上创建的USB设备外围设备? I am not sure how to start, but for example, on websites like connect.garmin.com they allow you to connect your Sat Nav and then transfer the data to the website after you have downloaded a application and restarted your browser.

我需要做些什么来研究将这个功能添加到我拥有的特定设备中。

直接?一般不会。

Browsers run websites are run in highly sandboxed environments. If you want to access a USB device you will need:

操作系统的驱动程序
增强的安全权限
接口(通常在其环境中相当有限,例如用于IE/Windows的ActiveX)

If you have an application, then it just needs to load an HTTP library, make use of a webservice that you provide, then open a URL (in the default browser) which is related to the updated data (e.g. by a unique ID returned by the webservice).
