[BUG] Regression in Linux 5.4.17 for JMicron JMS566 enclosure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I own a WD Blue 1TB hard drive that I use in combination with an Icy Box
IB-273StU3-B enclosure in order to plug it to my laptop using USB. It
worked fine with all the Linux versions I tried, up until 5.4.17.


Using Linux 5.3
---------------
Everything works as expected when I plug the drive, and I can mount the
partitions:

Other considerations
--------------------
This enclosure works as expected with another drive: I tried with an old
Fujitsu 250GB drive and was able to mount the partitions.

The WD drive works with a similar enclosure: the Icy Box IB-268U3-B
enclosure. It has the exact same vendor id and product id (357d:7788)
but a different bcdDevice (2.03).

Looking at the dmesg logs I pasted above, I see that the main difference
is the driver used:
- uas in Linux 5.3;
- usb-storage in Linux 5.4, since uas is blacklisted.


I believe the uas driver was blacklisted because of an old bug[1] in
Fedora. In Linux, the commit that disabled uas is
bc3bdb12bbb3492067c8719011576370e959a2e6.

I do not really mind not being able to use uas, however I would like to
be able to mount my partitions using usb-storage.
