SMART not available for OWC Dual Drive Dock (1e91:a4ae) in udisks2

## SMART not available for OWC Dual Drive Dock (1e91:a4ae) in udisks2

Summary:
The OWC USB-C Dual Drive Dock (USB ID 1e91:a4ae) is not recognized for SMART data by udisks2, meaning GNOME Disks shows no SMART information for drives connected through it. However, smartctl successfully retrieves full SMART data using SAT passthrough (-d sat), confirming the dock supports SMART passthrough at the hardware level.

Device:
OWC USB-C Dual Drive Dock
USB ID: 1e91:a4ae

The device appears as three entries in lsusb:
`
Bus 003 Device 003: ID 1e91:a4ae Other World Computing USB2.0 Hub
Bus 004 Device 006: ID 1e91:a4ae Other World Computing USB-C Dual Drive Dock
Bus 004 Device 007: ID 1e91:a4ae Other World Computing Dual Drive Dock 1
`

Test drive:
Seagate Archive HDD ST8000AS0002-1NA17Z (8TB) connected via the dock as /dev/sdb

Expected behavior:
udisks2 should recognize the OWC Dual Drive Dock and allow SMART data to be read through it, as it does for internally connected drives.

Actual behavior:
udisksctl info -b /dev/sdb returns no SMART-related fields whatsoever. GNOME Disks shows no SMART data for the drive.

Confirmed working with smartctl:
sudo smartctl -a -d sat /dev/sdb returns full SMART data and a passing health assessment, confirming SAT passthrough works with this dock.

Environment:

• Kernel: 6.19.9-201.nobara.fc43.x86_64
• smartmontools: 7.5 2025-04-30 r5714

Request:
Please add USB ID 1e91:a4ae to the udisks2 supported device database with SAT passthrough enabled, so GNOME Disks and other udisks2 consumers can read SMART data from drives connected via this dock.

Please add USB ID 1e91:a4ae to the udisks2 supported device database

Smartmontools does not provide an udisks2 supported device database. If this exists, please address this request to the related project.

A request for an entry in the smartmontools drivedb.h file always requires a sample smartctl -x -a to prove reasonable test coverage. Do not use -a only. Add -q noserial if desired.

Thank you for the clarification, Christian. I will file a separate request with the udisks2 project.

That said, I wanted to ask whether it would still be worth adding USB ID 1e91:a4ae (OWC USB-C Dual Drive Dock) to the smartmontools USB device database. Currently, smartctl requires the -d sat flag to be specified manually for this dock. If the device were added to the database, smartctl would be able to detect it automatically without needing the explicit flag.

For reference, sudo smartctl -a -d sat /dev/sdb works successfully with this dock and returns full SMART data, confirming SAT passthrough is supported at the hardware level.

Thank you for your time and for maintaining smartmontools.

Of course. But verbose (sometimes AI generated) descriptions do not help. Sample outputs are always required as already mentioned.

Please provide outputs of:

• smartctl -d sat -x -a /dev/sdb (optionally add -q noserial) (tests 48-bit ATA commands)
• smartctl -i /dev/sdb (tests USB Id detection)
