USB to Ethernet adapter / D-Link DUB-E100 / supported?

English Hardware
#1

The box in question is a Eee PC running openSUSE-11.1 i586. It is a firewall/router with the native Ethernet plug connected to the internet and a USB to LAN converter from ADMtek (AN8515) pointing to the LAN. It was running quite some time with the Pegasus II USB Ethernet driver, but it was running hot and probably failed, as I have no connection anymore.

I want to replace it by a D-Link DUB-E100 which seems to be of better quality. The manufacturer does not list it as compatible:

DUB-E100: USB 2.0 Fast Ethernet Adapter - Networking cards, switches and other network devices - D-Link, from D-Link Home

but according to The GNU/Linux “usbnet” Driver it should be supported. Anyone having practical experience with this device? Or comments?

So are you wanting to buy one and so you don’t have it yet to try? It looks like the information for one is kind of old, but indications are it worked with kernel 2.6.21.5. If you have not seen this one here is a page I found on it. Good luck.

Details for: D-Link Corp. DUB-E100

Thank You,

Just for the record: D-Link DUB-E100 was not on stock. I ordered one and should get it within a few days to test. In the meantime I bought a cheaper one from DeLOCK and found it works out of the box:

It really seems that most of these devices “just work”. DeLOCK even announced on the package that the device works with a linux kernel >= 2.6.11. That’s what I call a linux-friendly company. I will report on the DUB E-100 as soon as it’s available.
