Beryl (GL-MT1300) Max USB Tethering Speed

What is the maximum USB Tethering speed on the Beryl GL-MT1300? Specifically when connected to an iPhone or iPad. The Slate (GL-AR750S) has a maximum tethering speed of 30mbps. Which is usable but if the Beryl is capable of more it’ll be worth the upgrade for me.


Tethering via USB should be the same speed.
