从USB VID / PID查找可移动磁盘的Windows驱动器号 [英] Find Windows Drive Letter of a removable disk from USB VID/PID
问题描述
此问题之前曾有人提出过，并且有一个应该有效的答案此处。但是我已经尝试过了，但对我来说不起作用。
This question has been asked before, and there is one answer that supposedly works here. But I've tried it out and it does not work for me.
问题是Win32_DiskDrive上的查询返回的PNPDeviceID与 Device类返回的PNPDeviceID不同。例如，在我的情况下，查询返回类似-PNPDeviceID： USBSTOR\DISK& VEN_ABCD& PROD_1234& REV_0001\8& 2C3C9390& 0 ，而Device类返回实际的VID / PID组合- > USB\VID_4568& PID_QWER& MI_00\7& 15b8d7f0& 3& 0000 。
The issue is that the PNPDeviceID returned by the Query on Win32_DiskDrive and that returned by the "Device" class are different. For example in my case the Query returns something like - PNPDeviceID: USBSTOR\DISK&VEN_ABCD&PROD_1234&REV_0001\8&2C3C9390&0 while the Device class returns the actual VID/PID combination --> USB\VID_4568&PID_QWER&MI_00\7&15b8d7f0&3&0000.
因此，Win32_DiskDrive上的SELECT查询始终失败。
So the SELECT query on Win32_DiskDrive always fails.
主代码：
var usbDevices = GetUSBDevices();
//Enumerate the USB devices to see if any have specific VID/PID
foreach (var usbDevice in usbDevices)
{
if (usbDevice.DeviceID.Contains("ABCD") && usbDevice.DeviceID.Contains("1234"))
{
foreach (string name in usbDevice.GetDiskNames())
{
//Open dialog to show file names
Debug.WriteLine(name);
}
}
}
USBDeviceInfo类
USBDeviceInfo Class
class USBDeviceInfo
{
public USBDeviceInfo(string deviceID, string pnpDeviceID, string description)
{
this.DeviceID = deviceID;
this.PnpDeviceID = pnpDeviceID;
this.Description = description;
}
public string DeviceID { get; private set; }
public string PnpDeviceID { get; private set; }
public string Description { get; private set; }
public IEnumerable<string> GetDiskNames()
{
using (Device device = Device.Get(PnpDeviceID))
{
// get children devices
foreach (string childDeviceId in device.ChildrenPnpDeviceIds)
{
// get the drive object that correspond to this id (escape the id)
Debug.WriteLine(childDeviceId.Replace(@"\", @"\\") );
foreach (ManagementObject drive in new ManagementObjectSearcher("SELECT DeviceID FROM Win32_DiskDrive WHERE PNPDeviceID='" + childDeviceId.Replace(@"\", @"\\") + "'").Get())
{
foreach (PropertyData usb in drive.Properties){
if (usb.Value != null && usb.Value.ToString() != "")
{
Debug.Write(usb.Name + "=");
Debug.Write(usb.Value + "\r\n");
}
}
// associate physical disks with partitions
foreach (ManagementObject partition in new ManagementObjectSearcher("ASSOCIATORS OF {Win32_DiskDrive.DeviceID='" + drive["DeviceID"] + "'} WHERE AssocClass=Win32_DiskDriveToDiskPartition").Get())
{
// associate partitions with logical disks (drive letter volumes)
foreach (ManagementObject disk in new ManagementObjectSearcher("ASSOCIATORS OF {Win32_DiskPartition.DeviceID='" + partition["DeviceID"] + "'} WHERE AssocClass=Win32_LogicalDiskToPartition").Get())
{
yield return (string)disk["DeviceID"];
}
}
}
}
}
}
作为补充，我可以使用 Model属性传递获取查询，然后找到驱动器号，如此处。但是我正在寻找一种可以将VID / PID绑定到驱动器号的解决方案。
As a side note, I am able to get the Query using "Model" property pass and then find the drive letter, as explained here. But I'm looking for a solution that can tie VID/PID to the drive letter.
推荐答案
我遇到了完全相同的问题经过一周的辛苦工作，我终于找到了解决方案。
我还为一个设备获得了两个链接（带有vid和pid的链接以及一个包含 USBSTOR ....的链接）。我认为这不是解决问题的最佳方法，但是（直到现在）它仍然有效。
I had exactly the same problem and after a hard week of work I finally got the solution. I also get two links for one device (the link with the vid and pid and a link, which contains "USBSTOR...."). I think it's not the best way to solve the problem, but (until now) it works.
我使用了两个功能：
第一个是找到具有特定VID和PID的USBHub，并找到相关的第二个链接（ USBSTOR ....）。此链接很重要，因为它形成了与驱动器号的连接。
名为 USBobjects的列表包含许多相关链接（USBHub，USBSTOR等），这些链接引用了所有连接的设备。我发现，USBSTOR链接出现在该链接之后，该链接包含VID和PID。
我将 USBStOR ...链接存储为字符串，并将其用于第二个函数来查找磁盘驱动器的相关PNPEntity。
The first one is to find a USBHub with a specific VID and PID and also find the related second link ("USBSTOR...."). This link is important, because it forms the connection to the drive letter. A list named "USBobjects" contains a number of related links (USBHub, USBSTOR,....), which refer to all attached devices. I found out, that the USBSTOR link appears right after the link, which contains the VID and PID. I stored the "USBStOR..." link as a string and used it for the second function to find the related PNPEntity of the DiskDrive. This leads to the correct DiskPartition and furthermore to the LogicalDisk = drive letter.
希望不会太晚，这两个功能都可以帮助您！
Hopefully it's not to late and both functions will help u!
第一功能：
FIRST FUNCTION:
public void FindPath()
{
foreach (ManagementObject entity in new ManagementObjectSearcher("select * from Win32_USBHub Where DeviceID Like '%VID_XXXX&PID_XXXX%'").Get())
{
Entity = entity["DeviceID"].ToString();
foreach (ManagementObject controller in entity.GetRelated("Win32_USBController"))
{
foreach (ManagementObject obj in new ManagementObjectSearcher("ASSOCIATORS OF {Win32_USBController.DeviceID='" + controller["PNPDeviceID"].ToString() + "'}").Get())
{
if(obj.ToString().Contains("DeviceID"))
USBobjects.Add(obj["DeviceID"].ToString());
}
}
}
int VidPidposition = USBobjects.IndexOf(Entity);
for (int i = VidPidposition; i <= USBobjects.Count; i++ )
{
if (USBobjects[i].Contains("USBSTOR"))
{
Secondentity = USBobjects[i];
break;
}
}
}

第二个功能：
SECOND FUNCTION:
public void GetDriveLetter()
{
foreach (ManagementObject drive in new ManagementObjectSearcher("select * from Win32_DiskDrive").Get())
{
if (drive["PNPDeviceID"].ToString() == Secondentity)
{
foreach (ManagementObject o in drive.GetRelated("Win32_DiskPartition"))
{
foreach (ManagementObject i in o.GetRelated("Win32_LogicalDisk"))
{
Console.WriteLine("Disk: " + i["Name"].ToString());
}
}
}
}
}
