这篇博客介绍了如何使用Python简单检测U盘插入并获取盘符，但提到win32file模块在处理非NTFS文件系统时可能出现错误。为增加容错性，建议先判断文件系统类型。

import win32file

def getdrives():
    drives=[]
    sign=win32file.GetLogicalDrives()
    drive_all=["A:\\","B:\\","C:\\","D:\\","E:\\","F:\\","G:\\","H:\\","I:\\",
                "J:\\","K:\\","L:\\","M:\\","N:\\","O:\\","P:\\","Q:\\","R:\\",
                "S:\\","T:\\","U:\\","V:\\","W:\\","X:\\","Y:\\","Z:\\"]
    for i in range(25):
        if (sign&1<<i):
            if win32file.GetDriveType(drive_all[i])==3:
                drives.append(drive_all[i])
    return drives

def is_UDisk(drives):
    UDisk=[]
    for item in drives:
        try :
            free_bytes,total_bytes,total_free_bytes=win32file.GetDiskFreeSpaceEx(item)
            if (total_bytes/1024/1024/1024)<17:
                UDisk.append(item)
        except :
            break
    return UDisk

if __name__=="__main__":
    drives=is_UDisk(getdrives())
    print drives

U盘检测这部分，方法比较弱智，本来考虑监控进程U盘插入过程中windows的识别进程的，太麻烦了，仅供参考
