Hi there! First of all thanks for all the great work that you do here!
I did a fresh install of the latest nightly (5.26.170227) and I can't mount usb sotrage devices or acces their content.
The OPiZero detects the device but it doens't mount it. I can see the device by running
sudo fdisk -l
However if I try to mount it manually I get this error:
sudo mount /dev/sda /media/usb
mount: wrong fs type, bad option, bad superblock on /dev/sda,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
I've tried with three devices and none of them work with the OPZero. They all work on my PC and Raspberry pi.
