Hello everybody,

I'm/we're running FreeBSD 12.1-RELEASE-p10 GENERIC amd64 on an PC Engines APU.4D4 Board with a Transcend MSA230S SSD as main hard drive which is detected as ada0.
I would like to attach a hdd case that contains a Western Digital 14TB hard disk (already partitioned and formatted with a single ufs partition).
However the disk is not always detected, sometimes connecting it to another usb port (2 ports are available) works but not always.
Especially after a reboot the drive is not detected properly (I'm not 100% certain, but I believe it never was detected correctly after a reboot). When the disk is detected it is listed as da0.
The hdd case does seem to contain a JMicron usb controller, it's a icybox case with space for two 3.5" disks, but currently only contains the one WD hdd.

I've enabled automount like described in section 17.4.2. Automounting Removable Media of the handbook.
The same settings work flawlessly on other devices (same board, same os version) with external seagate hdds (though they are ready made solutions, not hdd cases that are made to be filled with drives by the user).

/etc/devd.conf
# automount
notify 100 {
        match "system"          "GEOM";
        match "subsystem"       "DEV";
        action "/usr/sbin/automount -c";
};

/etc/rc.conf
# automount
autofs_enable="YES"

I hope you can give me some hints and tips on how to get this disk working properly.

By the way, do you have any information about settings that reduce the power consumption of external disk drives?
We expect the disks to be mostly idle, but at the moment the power consumption looks pretty high (higher than the APU board itself), even when it is not currently accessed.
Especially information about usb power saving states and power consumption in combination with automount would be appreciated.

Thank you in advance.
