So, it seems that MODE SENSE (10) command completely wedges the device (or
maybe the controller) and it stops accepting any subsequent commands.
I wonder if it would work better with MODE SENSE (6) or if any form of MODE
SENSE is broken.
Are you set up for compiling and testing kernel code patches?
Or would you prefer that I send you pre-built kernels?

But before that, could you please obtain a log from a working Linux guest with
the problematic controller?
I am not sure how to get the log that I want as I am not very experienced with
Linux, but it should look something like this:
[ 3902.887849] usb 4-6: new SuperSpeed USB device number 6 using xhci_hcd
[ 3902.904584] usb 4-6: New USB device found, idVendor=152d, idProduct=0567

[ 3902.910769]  sde: sde1
[ 3902.912446] sd 13:0:0:0: [sde] Attached SCSI disk

I guess that this requires setting kernel log level to debug before attaching
the device and then extracting the logs from the appropriate place (dmesg?,
systemd journal?).
