Support for RaidSonic ICY BOX IB-1922MF-C32 USB to NVMe bridge (0x174c:0x2364, ASM2364)

[bugs.bunny]

Hello,

I'm unsure if this is a request for an enhancement or a case like "works as designed". So I apologize in advance if I'm wrong.

I'm using two RaidSonic ICY BOX IB-1922MF-C32 USB to NVMe bridges which have an ASMedia ASM2364 chipset inside. smartmontool is able to print out some information (please see attached outputs). But what moved me to open this ticket are the last lines of the output:

Warning: NVMe Get Log truncated to 0x200 bytes, 0x200 bytes zero filled
Error Information (NVMe Log 0x01, 16 of 256 entries)

No matter what tests I run, I don't get any attributes displayed.

Thank you in advance for your support! If you need additional information, outputs, ... please let me know!

Warning: NVMe Get Log truncated to 0x200 bytes, 0x200 bytes zero filled

The 0x200 bytes are a limitation of the vendor specific NVMe pass-through SCSI command of this USB bridge.

No matter what tests I run, I don't get any attributes displayed.

Of course there is SMART information:

SMART/Health Information (NVMe Log 0x02)
Critical Warning:                   0x00
Temperature:                        28 Celsius
Available Spare:                    100%
...

Diagnostic info of (S)ATA, SCSI/SAS and NVMe devices differ considerably and so do smartctl outputs. In particular, NVMe devices do not support ATA-like SMART Attributes.

Smartctl works as expected, see above comment for details.
