If you know the name of your device, find the USB Bus and Device nubmers:

$ lsusb
...
Bus 002 Device 005: ID xxxx:yyyy MyDeviceManufacturer
...

Then look at the USB tree and find your device (mine was Bus 2, Dev 5):

$ lsusb -t
...
/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M
    |__ Port 2: Dev 5, If 0, Class=Mass Storage, Driver=uas, 5000M
    |__ Port 4: Dev 3, If 0, Class=Mass Storage, Driver=usb-storage, 5000M
...

You can see in my case the uas driver.

If UAS is not in use you would see usb-storage (like Dev 3 in my case).
