I bought this device because its reviews said it worked under Ubuntu. However, there are no drivers for ubuntu on the website.
I did install DKMS, which is the first step according to their website, before installing the drivers.
I installed the Display Link drivers, but it still didn't work. (I did restart.)
Using lsusb I found this information about the device:
Bus 004 Device 002: ID 0711:5601 Magic Control Technology Corp.
I googled for Magic Control Technology Corp linux drivers, found information about "userful" drivers, but couldn't find a download link.
