Turris Mox USB (from module A) not working any more (for mass storage) after TOS 6.0 upgrade

MOX classic, HBK branch (i.e. 6.0.4), .5 GB, 2x WiFi, simple config.

Unfortunately, only couple of minutes ago I noticed that external USB 3 does not work :-((( I took its work for granted and didn’t checked.

There are no errors in system log. It is even recognized as USB 3 (“Dec 5 14:35:54 MOXjp kernel: [ 1.322502] xhci-hcd d0058000.usb: Host supports USB 3.0 SuperSpeed”).

Flash disk itself is OK - checked in Ubuntu NB, saw its content OK.

Unfortunately I can’t tell when this happened, most probably sometimes after some 6.0.x update.

If needed, can send logs and/or diagnostics to support - @pepe ?

Edit: last entry in syslog was :
Nov 29 20:27:36 MOXjp crond[3704]: (cron) INFO (Shutting down)
when syslog was linked to /srv/log/messages on this USB3.
