Hi Ostracus,
Are there any files stored in your USB drive?
If the drive is empty, can you add some files to it first and try again.
Login to the device web page as admin to make sure you can see everything.
We are still checking on this problem.
We have not been able to reproduce the problem yet.
However, if the USB drive is empty, the OBi will report "USB Device Not Found".
We consider this a bug and will be fixed.
Thank you.
