I would like to understand before buying one, if OpenWRT supports a USB Hub (http://www.amazon.com/AmazonBasics-Port … B00DQFGH80) so I can use for a project the one USB port on the MR3020 to connect:
- USB Mass Storage device (16GB) for SWAP and EXT4 partition
- USB 4G Modem Dongle to connect it to mobile internet

If it can support it, which packages are needed beside:
- block mount
- kmod fs ext4
- kmod usb storage

And, does have people experience using one USB Hub?

Any experience which USB 3G/4G Modem Dongles are supported by Openwrt 15.05?

Hubs are no problem for OpenWrt. I have a cascade of 4port -> 10 port -> 2x 7port in heavy use. 4port is bus powered, 10 + 2x7 port are self powered.

If a single USB device is working on your router, then USB hubs will work too. Just install the standard packages for USB support, and if you need storage, additional packages for USB storage.
