[Orange Pi Zero] USB storage devices unmountable

[philippnbg]

I tried mounting an USB3 HDD, USB3 pendrive and USB2 pendrive using the single USB2.0 A port.
They are recognised in the host OS in dmesg and via lsusb, though can not be seen in /dev/sdX or via fdisk -l and are therefore not mountable. All three USB devices are mountable from raspberry pi zero and raspberry pi 3 balena images.
I noticed, that the usb-storage module is not loaded (but I don't know, if it is needed to mount USB storage devices).

BalenaOS: balenaOS 2.31.5+rev1
Supervisor version: 9.11.3

relevant output of dmesg:

[ 697.720053] usb 3-1: USB disconnect, device number 2
[ 701.810803] usb 3-1: new high-speed USB device number 3 using ehci-platform

I would say the usb-storage module is not a part of the orange pi zero image. Therefore you would have to enable it in the defconfig for kernel 4.17.3. However you would have to check with the balena guys if they want it on every build of every device in the allwinner platform.

The config string you are looking for is:
CONFIG_USB_STORAGE=y

You could make a build yourself by taking a look at the provided balena-yocto-scripts/automation/jenkins-build.sh.
