That is the cleanest method I am aware of, anything else is going to rely either on disk_events per @Hugh (Zercurity)ā€™s suggestion, or some lossy attempts at association through non-unique things like
model_name

One thing you should consider @ET is that a device which interfaces via PCI-Express (eg. an NVME SSD within a Thunderbolt 3 enclosure) will not register itself as a USB device

eg.
osquery> SELECT * FROM block_devices WHERE type = 'PCI-Express' AND model = 'Sabrent';
+--------------+------------+--------+---------+------------+------------+--------------------------------------+-------------+----------------------+
| name         | parent     | vendor | model   | size       | block_size | uuid                                 | type        | label                |
+--------------+------------+--------+---------+------------+------------+--------------------------------------+-------------+----------------------+

I tried your idea and I got a duplicate answer:
+---------------+-------------+---------+--------------+-----------+------------+------+------+----------------------------+
| name          | parent      | vendor  | model        | size      | block_size | uuid | type | label                      |
+---------------+-------------+---------+--------------+-----------+------------+------+------+----------------------------+
| /dev/disk11   |             | SanDisk | Cruzer Blade | 120225792 | 512        |      | USB  | SanDisk Cruzer Blade Media |
| /dev/disk11s1 | /dev/disk11 | SanDisk | Cruzer Blade | 120223744 | 512        |      | USB  | Untitled 1                 |
+---------------+-------------+---------+--------------+-----------+------------+------+------+----------------------------+
Do you know why?

@ET the query I provided is looking at all block_devices which will grab each partition on a given disk, hence the different labels for parent container and the child partition
SanDisk Cruzer Blade Media/Untitled 1
, if you wanted to filter down the results you could look for block_devices with no
parent

Try this for example:
SELECT * FROM block_devices WHERE parent = '';

@ET I haven't done as much removable media exploration as I would like but it appears from my poking that you can also get
mounted_at
time from the
fseventd-uuid
file present in the
/.fseventsd
path of the mount:
WITH removable_media AS (
  select 
    m.device,
    m.path, 
    bd.type,
    ROUND((m.blocks * m.blocks_size / (1000 * 1000 * 1000)), 2) volume_total_gb,
    ROUND((1.0 * m.blocks_free * blocks_size / (1000 * 1000 * 1000)), 2) volume_free_gb,
    ROUND((100.0 * m.blocks_free / m.blocks), 2) AS volume_free_percent,
    bd.vendor, 
    bd.model, 
    bd.uuid, 
    bd.label 
  FROM mounts m, block_devices bd 
  WHERE m.device = bd.name 
  AND path like '/Volumes/%' 
  AND bd.type != 'Virtual Interface')
SELECT 
  rm.*, 
  datetime(f.mtime, 'unixepoch') AS mounted_at 
FROM removable_media rm, file f 
WHERE f.path = rm.path || '/.fseventsd/fseventsd-uuid';
