I'm getting UAS errors using a USB 3.0 SATA enclosure (StarTech
S3510BMU33ET; 174c:55aa)
This appears to have an ASM1053 chipset which, as far as my reading of
uas_use_uas_driver() goes, should have a working UAS providing we
restrict the size of the transfer?
i.e. MaxPower is 36, and MaxStreams is 16, which should imply ASM1053,
with working UAS, but with US_FL_MAX_SECTORS_240.
That should be done for us, according to the code, but just to be sure,
as I'm using the Debian (unstable) kernel 4.3.3, I added the
US_FL_MAX_SECTORS_240 quirk myself:
getz $ grep usb-storage /etc/modprobe.d/uas-blacklist.conf
options usb-storage quirks=174c:55aa:g
[but is that still used if UAS is active? I get no "Quirks match"
message for 'g', unlike I do for UAS disable 'u']
With that 'g' in place, I get reams of UAS errors/resets, and the device
is unusable.
If I change the quirk to 'u', to disable UAS:
options usb-storage quirks=174c:55aa:u
then things work, but the performance is dire (e.g. 8MB/s writes).
Should this particular device be working? It doesn't seem to, so should
the detection logic in uas_use_uas_driver() be disabling UAS for my device?
Or am I missing something?
The disk in the enclosure is a WD30EZRX (WD Green 3TB)
Appended dmesg and lsusb excerpts.
any comments, please?
thanks much indeed.
cheers,
calum.
