I have a JMS581DL USB 3.2 Gen2x1 to PCIe NVMe Gen3 x2 / SATA 6Gbps bridge.

VERY IMPORTANT: this is a dual protocol Nvme+Sata bridge.

The jms581dl chip is not in the smartmontools' database, so I have to manually specify the type with -d option.

If m2 nvme is placed in the bridge, -d sntjmicron works.
If m2 sata is placed in the bridge, -d sat works.

I cannot find a type that works for both nvme and sata.
I don't know how to figure out programmatically if an nvme or a sata is placed in the bridge.
The only physical difference is that an LED is turning blue when nvme is connected, and red when sata is connected.

Here is an lsusb of the usb bridge:

VERY IMPORTANT: this is a dual protocol Nvme+Sata bridge.

This is not yet supported, Currently we could only add one -d option. This should only be done if the bridge behaves sane if the wrong device type is connected.

If m2 nvme is placed in the bridge, -d sntjmicron works.
If m2 sata is placed in the bridge, -d sat works.

Please test the opposite behavior.

Possibly related: #331.

Important: -d usbjmicron could only be added if this behaves sane if a SATA device is connected.

-d sat could not be added as this USB Id reportedly (#331) is also used for NVMe-only docking stations.

If possible, please try a r5677 (6306b06) or later build with new -d usbjmicron/sat option. Should work with both NVMe and SATA devices.
