Unfortunately this log is uninterpretable, thanks largely to the two 
mass-storage devices at addresses 9 and 10.  I can't tell what they
are because they don't appear to be listed in the dmesg log you
posted.

The device at address 10 isn't working at all.  It apparently has 4
LUNs but it replies to all commands for all LUNs with an error code
saying that the LUN isn't supported.

The device at address 9 is working, but its I/O clutters up the log.

There's also something at address 4; perhaps an HID device, I can't
tell.

Can you run the test again, this time with no extraneous USB devices 
plugged in?  (That includes hubs.)  And before starting the test, 
collect the contents of /sys/kernel/debug/usb/devices (you'll probably 
have to mount /sys/kernel/debug first).
