Using usb-storage with extroot

Installing and Using OpenWrt
1

Hi,

Currently using crucial X6 disk with extroot, connected to the router, that has some problems with UAS driver (usb 2-1: cmd cmplt err -71, uas_eh_abort_handler). Even with these errors, it manages to load the exroot and used the overlay on the disk, but it's really slow and with interruptions.
So, I've tried to use driver usb-storage with quirks and I can use my disk with it, but not on the boot and it defaults to the internal overlay. I see this on the logs:

I'm sure I'm missing something pretty obvious but still dont understand much of this, been reading and using AI to move forward.

Thanks!

Edit: after the boot, I end up with this:

root@OpenWrt:~# lsusb -t
/: Bus 001.Port 001: Dev 001, Class=root_hub, Driver=xhci-mtk/2p, 480M
/: Bus 002.Port 001: Dev 001, Class=root_hub, Driver=xhci-mtk/1p, 20000M/x2
|__ Port 001: Dev 002, If 0, Class=[unknown], Driver=[none], 5000M/x2
root@OpenWrt:~#

But I can see the quirk:
root@OpenWrt:~# cat /etc/modules.d/54-usb-storage
usb-storage quirks=0634:5602:u
root@OpenWrt:~#

2

Are you sure the disk is usable after booting with internal overlay?

3

not imediately, I have to load the driver manually:

root@OpenWrt:~# echo "0634:5602:u" > /sys/module/usb_storage/parameters/quirks
root@OpenWrt:~# echo 0 > /sys/bus/usb/devices/2-1/authorized
root@OpenWrt:~# echo 1 > /sys/bus/usb/devices/2-1/authorized
root@OpenWrt:~# lsusb -t
/:  Bus 001.Port 001: Dev 001, Class=root_hub, Driver=xhci-mtk/2p, 480M
/:  Bus 002.Port 001: Dev 001, Class=root_hub, Driver=xhci-mtk/1p, 20000M/x2
    |__ Port 001: Dev 002, If 0, Class=[unknown], Driver=usb-storage, 5000M/x2
root@OpenWrt:~#

what bugs me is that with UAS, he can initiate the disk during boot and the subsequent external overlay (just very slow because of the errors from UAS), but cant seem to do it with usb-storage

4

If you're not using the UAS driver for anything else, can you try uninstalling kmod-usb-storage-uas and install kmod-usb-storage instead?

5

You were told this in your old thread too.

just did it, but with the same result:

and I have the quirk:
root@OpenWrt:~# cat /etc/modules.d/usb-storage
usb-storage quirks=0634:5602:u

@frollic - I know and it was working, the attended sysupgrade to 25.12.1 messed this up. After the upgrade, couldn't anymore load the external overlay with usb-storage. Really not sure what I did different the first time, tried everything already! I just tried with UAS again, to check if I could retrace all my steps

Thanks for bearing with me

Honestly, I have little knowledge about how usb-storage quirks should work with modules.d, but you don't need the quirks anymore now that you don't have the UAS driver. Try removing that file?

EDIT: The /etc/modules.d/usb-storage file, just to clarify.

ok, just did a fresh flash, reinstalled everything and it's working fine, with external overlay on the disk. Not sure what happened during the upgrade, but something went wrong

Thank you both for the help, really appreciated!
