Hi Martin,

Thanks for responding. I tried your patch but it, unfortunately, did not 
help with the issue I and Tasos were having. Not on its own, and not 
with LaCie:Rugged FW USB3:0x2000 added to /proc/scsi/device_info.
Just to make sure we are talking about the same problem: prior to 
c92a6b5d6335, the drive would be usable pretty much immediately after 
connecting - in the logs this manifests by the following rows appearing:

Feb 13 18:59:42 kernel:  sdb: sdb1 sdb2
Feb 13 18:59:42 kernel: sd 8:0:0:0: [sdb] Attached SCSI disk

After c92a6b5d6335, one or more restarts are required (below is from 
Fedora's 6.7.4 with your patch applied on top):

Four resets are needed with the current kernel-6.7.4. With early 5.19 
kernels on and after 7fb019c46eee it needed one reset, with c92a6b5d6335 
and with e60ac0b9e445 multiple resets were needed too. As 30 seconds 
need to pass between the resets, it does take a while until the drive 
can be used.
I did not test other commits between c92a6b5d6335 and c92a6b5d6335 as I 
was bisecting and only tested the commits suggested by git.
6.7.4 I tested with bare metal Fedora 39, 5.19 with a Fedora 36 VM.
If this was already clear, please feel free to ignore.
In case it is relevant: my drive (but not Tasos') is patched to use 
US_FL_NO_REPORT_OPCODES | US_FL_NO_SAME.

Best regards,
Julian
