获取产品ID和供应商ID

Question

大家好，有一种方法可以使用Java或C＃获取供应商ID，而产品是USB设备的

Answer 1

Did you take a look at jUSB ? Granted, it is quite old and not updated, but it seems usb.core API is working for both Linux and Windows.

It's worth taking note I think, how conveniently the DeviceDesriptor class, residing in just the mentioned usb.core package provides getVendorId() and getDeviceId() methods.

Answer 2

USB device are identified by their vendor id and product id . Those IDs are consisting of a prefix ( vid_ for vendor id or pid_ for product id) and a 4 digit HEX number. The MAX3420E for example has the vendor id vid_06ba and the product id pid_5346 .
