To have some more connection options for different embedded devices I bought a port replicator. My favorite dealer offered an adequate device from DeLock: DeLock USB 2.0 Port Replicator (87503). It supports DVI (and also VGA using an adapter), powered USB and Ethernet. But according to the device description and according to DeLock the device doesn’t support Linux. I asked which graphic chip is inside this device and I get a quick response: DisplayLink’s DL-165. This chip is supported by Linux using the udlfb driver. There are other drivers needed for the rest of the functionality, so I was not sure it is really working completely with Linux. but I’m an optimist, so I ordered the device… 🙂
Now I could take a look at it: The device consists of an USB-Hub, an ASIX AX88772 USB 2.0 Ethernet adapter and the mentioned DisplayLink DL-165 adapter. All devices are being detected by my Ubuntu 11.10 (Oneiric Ocelot) without additional packages. The output of dmesg shows the detected devices. My monitor turned to the udlfb green as expected.
