Python: get name of a USB flash drive device [windows]

Question

I\'m trying to write little program which will be able to read some informations about REMOVEABLE_DEVICE (USB). I\'ve tried pyusb but I was not able to pull data I need.

Answer 1

I used the approach of @adrianus and improved a bit on it to return multiple usb drives. For how it works check his answer. For quick and dirty code that hopefully works for you check below :)

def get_usb_volume_name():  # pragma: no cover
    str_computer = "."
    logical_disk_device_ids = []
    volumes = []
    try:
        obj_wmi_service = win32com.client.Dispatch("WbemScripting.SWbemLocator")
        obj_swbem_services = obj_wmi_service.ConnectServer(str_computer, "root\cimv2")

    # 1. Win32_DiskDrive
    col_items = obj_swbem_services.ExecQuery("SELECT * FROM Win32_DiskDrive WHERE InterfaceType = \"USB\"")
    for item in col_items:
        disk_drive_device_ids = item.DeviceID.replace('\\', '').replace('.', '')

    # 2. Win32_DiskDriveToDiskPartition
    col_items = obj_swbem_services.ExecQuery("SELECT * from Win32_DiskDriveToDiskPartition")
    disk_partition_device_ids = []
    for obj_item in col_items:
        for disk_drive_device_id in disk_drive_device_ids:
            if disk_drive_device_id in str(obj_item.Antecedent):
                disk_partition_device_ids.append(obj_item.Dependent.split('=')[1].replace('"', ''))
                break

    # 3. Win32_LogicalDiskToPartition
    col_items = obj_swbem_services.ExecQuery("SELECT * from Win32_LogicalDiskToPartition")
    for objItem in col_items:
        for disk_partition_device_id in disk_partition_device_ids:

            if disk_partition_device_id in str(objItem.Antecedent):
                logical_disk_device_ids.append(objItem.Dependent.split('=')[1].replace('"', ''))
                break

    # 4. Win32_LogicalDisk
    col_items = []
    for logical_disk_device_id in logical_disk_device_ids:
        col_items.append(obj_swbem_services.ExecQuery("SELECT * from Win32_LogicalDisk WHERE DeviceID=\"" +
                                                      logical_disk_device_id + "\""))

    for col_item in col_items:
        volumes.append(col_item[0].VolumeName)
except IndexError:
    pass
volumes_result = []
logical_disk_device_ids_result = []
for i in range(len(volumes)):
    if volumes[i] != "":
        volumes_result.append(volumes[i])
        logical_disk_device_ids_result.append(logical_disk_device_ids[i])

return logical_disk_device_ids_result, volumes_result
