我正在尝试编写一个能够读取有关REMOVEABLE_DEVICE(USB)的一些信息的小程序。我已经尝试了pyusb,但我无法提取我需要的数据。
我想从系统中读取USB设备的名称。
采用以下格式:
USB Flash Memory - this is the model information
Removable Disk (H:) - this is the name of device
Generic Flash Disk
USB DISK (F:)
Lexar USB Flash Drive
Lexar (I:)
我能够通过 win32com.client 库获取模型信息,灵感来自here,但我无法获得Windows资源管理器中显示的设备名称。
也许我使用的是错误的图书馆?
这是我的代码:
import win32com.client
strComputer = "."
objWMIService = win32com.client.Dispatch("WbemScripting.SWbemLocator")
objSWbemServices = objWMIService.ConnectServer(strComputer,"root\cimv2")
colItems = objSWbemServices.ExecQuery("SELECT * FROM Win32_DiskDrive WHERE InterfaceType = \"USB\"")
for objItem in colItems:
if objItem.Caption != None:
print "Caption:" + ` objItem.Caption[:-11]`
以下是Windows Win32_DiskDrive类的链接:link
提前感谢您的帮助。

我看起来很奇怪,但它会起作用(获取所有可移动卷的列表Label's
)
import os
os.system('echo list volume > Ravi.txt')
path1 = os.path.join(os.getcwd(),"Ravi.txt")
os.system('diskpart /s '+path1+' > logfile.txt')
path2 = os.path.join(os.getcwd(),"logfile.txt")
Str = open(path2).read()
Str = Str.split('\n')
matching = [s for s in Str if "Removable" in s]
for i in matching:
i = ' '.join(i.split())
i = i.split(" ")
print i[3]+"("+i[2]+":)"
<强>输出强>

免责声明:我对win32com.client
库没有任何经验。
首先使用Win32_DiskDrive
开头,我过去了Win32_DiskDriveToDiskPartition
和Win32_LogicalDiskToPartition
,然后转到Win32_LogicalDisk
以获得 VolumeName
< / strong>这似乎是你想要的。
import win32com.client
strComputer = "."
objWMIService = win32com.client.Dispatch("WbemScripting.SWbemLocator")
objSWbemServices = objWMIService.ConnectServer(strComputer,"root\cimv2")
# 1. Win32_DiskDrive
colItems = objSWbemServices.ExecQuery("SELECT * FROM Win32_DiskDrive WHERE InterfaceType = \"USB\"")
DiskDrive_DeviceID = colItems[0].DeviceID.replace('\\', '').replace('.', '')
DiskDrive_Caption = colItems[0].Caption
print 'DiskDrive DeviceID:', DiskDrive_DeviceID
# 2. Win32_DiskDriveToDiskPartition
colItems = objSWbemServices.ExecQuery("SELECT * from Win32_DiskDriveToDiskPartition")
for objItem in colItems:
if DiskDrive_DeviceID in str(objItem.Antecedent):
DiskPartition_DeviceID = objItem.Dependent.split('=')[1].replace('"', '')
print 'DiskPartition DeviceID:', DiskPartition_DeviceID
# 3. Win32_LogicalDiskToPartition
colItems = objSWbemServices.ExecQuery("SELECT * from Win32_LogicalDiskToPartition")
for objItem in colItems:
if DiskPartition_DeviceID in str(objItem.Antecedent):
LogicalDisk_DeviceID = objItem.Dependent.split('=')[1].replace('"', '')
print 'LogicalDisk DeviceID:', LogicalDisk_DeviceID
# 4. Win32_LogicalDisk
colItems = objSWbemServices.ExecQuery("SELECT * from Win32_LogicalDisk WHERE DeviceID=\"" + LogicalDisk_DeviceID + "\"")
print 'LogicalDisk VolumeName:', colItems[0].VolumeName
print
# putting it together
print DiskDrive_Caption
print colItems[0].VolumeName, '(' + LogicalDisk_DeviceID + ')'
适合我:
DiskDrive DeviceID: PHYSICALDRIVE1
DiskPartition DeviceID: Disk #1, Partition #0
LogicalDisk DeviceID: D:
LogicalDisk VolumeName: PENDRIVE
Sony Storage Media USB Device
PENDRIVE (D:)
这似乎提供了一种复杂但可能的方式,也许你可以简化它。我唯一的简化就是遗漏Win32_DiskPartition
,因为我们只需要连接。
请注意:
\\.\PHYSICALDRIVE1
之类的方法,但应该可以摆脱.replace()
- 方法。JOIN
类似于SQL?)。答案 2 :(得分:0)
我使用@adrianus的方法并对其进行了一些改进以返回多个USB驱动器。如何运作检查他的答案。对于希望适合您的快速和脏代码,请查看以下内容:)
