Add support for Realtek RTL9210B USB to SATA bridge

[David]

I just bought a Sabrent USB adapter containing the RTL9210B which supports both NVME and SATA M.2 disks. I have a SATA disk installed but I can´t read any smart data. Would it be possible to add support for this chipset? I saw another ticket, 1315, asking for added support, but then for the chipset without B, which seems only NVME.
I now get (when using smartctl -d scsi -a /dev/sdb):

If I execute: smartctl -d test -a /dev/sdb I get:

/dev/sdb [USB NVMe Realtek]: Device of type 'sntrealtek' [NVMe] detected
/dev/sdb [USB NVMe Realtek]: Device of type 'sntrealtek' [NVMe] opened

Thanks in advance.

[Christian Franke]

Please try smartctl -d sat -i /dev/sdb.

[David]

smartctl -d sat -i /dev/sdb

Yes, that works! Wow! I had been trying many types, must have skipped this one. Thanks a lot.

Ps. I changed it to worksforme, if that´s ok

[Christian Franke]

Yes, worksforme is OK.

Most regular (non-NVMe) USB -> SATA bridges support the vendor independent SCSI/ATA Translation (SAT) ATA pass-through command. It is good that the RTL9210B also supports this if a SATA M.2 SSD is connected.

[Christian Franke]

Does the RTL9210B behave sane if -d sntrealtek (or no -d option) is used and a SATA SSD is connected?

Also applies to the opposite case: If -d sat is used and a NVMe SSD is connected?

Smartctl should print ... scsi error unsupported field in scsi command or similar. This should not trigger any device hangs or disconnects.

A sane behavior would allow to implement auto-detection of the device type. Option -d sat would be no longer needed then.

With the SATA disk:

smartctl -d sntrealtek -a /dev/sdb

Read NVMe Identify Controller failed: scsi error unsupported scsi opcode

I don´t have a NVMe SSD so can´t test

Btw, lsusb shows "ID 0bda:9210 Realtek Semiconductor Corp. RTL9210 M.2 NVME Adapter"
which is the same as the RTL9210 as I saw in the ticket 1315

Good to know. I have another USB SSD, from Crucial, the X8, but I don´t know what kind of drive is in it, except for the size, and haven´t been able to get a smart read out except some basic knowledge when using -d scsi. Is there a way to get to the smart data? It is enabled and Crucial´s windows software can read it ok, but I would like to get the info in Linux.

[Christian Franke]

See the USB wiki page for possible -d options. The specs of the Crucial X8 suggest that it might use a USB -> NVMe (instead of SATA) bridge internally. As this is outside the scope of this ticket, feel free to create a new ticket of you could provide further information.

I have an USB adapter from Ugreen (CM559) with the same chip, and tested it with both NVMe and SATA SSDs.

I didn't try with -T permissive.

Smartctl should print ... scsi error unsupported field in scsi command or similar. This should not trigger any device hangs or disconnects.

The error with a SATA SSD looks similar to me. I did not observe any device hangs or disconnects with either SSD.

A sane behavior would allow to implement auto-detection of the device type. Option -d sat would be no longer needed then.

That would be lovely. Please let me know if you need further information.

Edit: Same results with build 1810 from builds.smartmontools.org.
