As it shown in the user guide, Jolla tablet have micro-usb OTG. I don't understand how it should work.
I have two otg connectors and two micro usb adapters, all of them working without any problem on android tablet. But when I connect them to Jolla tablet nothing happens...
Can someone explain what the problem? Why I can't see connected card via usb otg ?
Thanks

UPDATE:
Coderus answered how to mount it: http://talk.maemo.org/showpost.php?p=1501163&postcount=68

mount /dev/sda1 /usb
### ......
umount /usb

In this case I don't understand your previous post... You think my Jolla tablet was a android tablet and they flashed Sailfish OS on it ? This is a reason it not work ?

You misunderstood,the hardware supports OTG,but the OS not supports.

Very cool, thanks. Installed, but it need something from user side ?
I checked service and this what I get:
[root@Jolla nemo]# systemctl status mount-usbstick@.service Failed to issue method call: Unit name mount-usbstick@.service is not valid. [root@Jolla nemo]#
And from your script, if I understand right, it should mount to /media/usbstick, why not to /home/nemo/usbstick ?
Thanks

Never mind, it work like a charm, I found my stick in /media/usbstick :D Now we need just connect and navigate with FileCase to /media/usbstick. Thank you very much!

We also can create symlink to /home/nemo and it work perfectly with FileCase :)

[nemo@Jolla ~]$ ln -s /media/usbstick /home/nemo/USBstick

Do you need to umount manually or power off device before pulling out USB mass storage?

I ask myself the same question: how can I umount USB? I've installed usbstick-util, and USB mount automatically when I connect it. However, I can't umount USB (I've tried with umount, but It doesn't work).
