filogic: xhci-mtk: reset usb disk device when write data about openwrt HOT 20 OPEN

ok, so probably you are right with RTL9210B-CG. This device works without UAS. The second one unfortunately not.
Openwrt usb_storage module ignore parameters when you load module with modprobe or modprobe.conf defined parameters. The workaround looks like :
a) remove file: /etc/modules.d/usb-storage-uas
b) add to the rc.local:

echo -n "quirks=0bda:9210:u" > /sys/module/usb_storage/parameters/quirks 
usbreset 0bda:9210
echo "0bda 9210" > /sys/module/usb_storage/drivers/usb:usb-storage/new_id

performance:

Hi, thanks for advice but it will not solve root cause and probably will improve only stability a little bit.

Uninstall uas driver, no ncq no tears

Uninstall uas driver, no ncq no tears

Without uas I cant detect these disks. Is there other kernel drivers which supports these device classes ?

from openwrt.

usb-storage driver must support each and every uac disk.

When I remove uas :

Here we speak about two enclosures. I think the case which you paste is different.

yeah, totally different, just strange you dont enjoy your wildly enhanced uas mode.

from openwrt.

rebuild uas with patch.

Alternatively try with some "rolling" linux distribution just to confirm that there is no UAS for this device and it works.

It has to be backporyed in this case...

from openwrt.

but its nothing new, As you can see, newest kernel contain only detect function in the uas driver and doesn't have any exception. It's not only one chip which have this problem. More less it looks like problem with USB host driver.

from openwrt.

The newest kernel disables uas for particulat usb target, whose problem exhibits independently of host.

from openwrt.

OK. So I don't understood why it not happen on the 3 tested x86 hosts where any exceptions hasn't been added.

from openwrt.

It is happening on raspberry if you google. I am baffled why storage driver does not attach without uas though.
