Hello,

the external USB drive recently stopped being recognized at all by this server.

FreeBSD files.local 11.4-RELEASE-p2 FreeBSD 11.4-RELEASE-p2 #0: Tue Aug  4 19:21:02 UTC 2020     root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  amd64

This setup has worked for over 2 years, unfortunately I cannot tell to
which date, or to which update it correlates to.  This server is updated
with freebsd-update and pkg (binary packages only), typically a few days
after any security advisory comes out.

Currently nothing happens when I attach or remove the drive from tany USB port
of the Supermicor X8SIL motherboard. No BIOS changes were made in over a year.
At this time, neither dmesg, usbconfig devlist nor camcontrol show the disk.
I tried rollback from 11.3-RELEASE-p12 to 11.3-RELEASE-p11 and that did not work 
either, before upgrading all the way to 11.4-RELEASE-p2.

What debugging should I try next? 

The disk is recognized OK on a CentOS 7 server with similar hardware and on my 
MacbookPro.


I do have an older dmesg excerpt from when it had kernel 11.3-RELEASE-p11 and it
still worked:

ugen1.3: <JMicron JMS579> at usbus1
umass0 on uhub2
umass0: <JMicron JMS579, class 0/0, rev 2.10/32.02, addr 3> on usbus1

Thanks, andreas
