Note: This test doesn't rely on boardenv_* configuration values but it can
change the test behavior. To test USB file system cases (fat32, ext2, ext4),
USB device should be formatted and valid partitions should be created for
different file system, otherwise it may leads to failure. This test will be
skipped if the USB device is not detected.

# Setup env__usb_device_test_skip to not skipping the test. By default, its
