6.5.6.1 Determining USB device information for Windows
To obtain the Vendor ID and the Product ID for a USB device on Windows, perform the following steps:
1.
Open the device manager.
●
Go to the Control Panel and run "System"
●
Select the "Hardware" tab
●
Select the "Device Manager" button, this runs the device manager program.
2. Double click on the Universal Serial Bus Controllers
3.
Double click on the specific device, which brings up a separate window.
4. Select the Details tab and select one of the following properties from the pull down menu:
●
"Hardware Ids" property—This property shows the Vendor ID, Product ID and Revision for
the device. The Vendor ID is the 4 hex digits after "Vid_". The Product ID is the 4 hex digits
after "Pid_". The Revision is the 4 hex digits after "Rev_". For example, an iPod has a
"Hardware Ids" property that looks like this:
USB\Vid_05ac&Pid_120a&Rev_0001
This gives us the following values:
iPod Vendor ID： 0x05AC
iPod Product ID： 0x120A
iPod Revision： 0x0001
●
"Compatible Ids" property—This property shows the class code, subclass code and protocol
code for the device. The class code is the 2 hex digits after "Class_". The subclass code is
the 2 hex digits after the "SubClass_". The protocol code is the 2 hex digits after the "Prot_".
For example, an iPod has a "Compatible Ids" property that looks like this:
USB\Class_08&SubClass_06&Prot_50
This gives us the following values:
iPod Class Code：08（Mass Storage Device）
iPod Subclass Code：06（SCSI transparent command set）
iPod Protocol Code：50（Bulk-only transport）
