I don't think it is a duplicated one with bug #500069.

lowered speed, but seems no such kind of errors in bug #500069.
In fact, long ago, there were a patch[1](just a quirk) to make the
device[152d:2329] work well, so
it is a regression?
Considered it is easily reproduced for you, could you provide some usbmon data
to
help fix the problem?
About how to trace usbmon, see Documentation/usb/usbmon.txt.

USB: storage: Avoid I/O errors when issuing SCSI ioctls to JMicron USB/ATA
bridge
Here's the patch that implements the fix you suggested to avoid the
I/O errors that I was running into with my new USB enclosure with a
JMicron USB/ATA bridge, while issuing scsi-io USN or other such
queries used by Fedora's mkinitrd.
