USB Ethernet adapters for the Cr-48?

The wi-fi where I use my Cr-48 most of the time is flaky and oversubscribed, so I went ahead and ordered a USB ethernet adapter. The latest Cr-48 Mario build includes driver support for the following:

  • ASIX AX8817X based USB 2.0 Ethernet Devices
  • USB CDC Ethernet devices
  • Davicom DM9601 USB 1.1 ethernet devices
  • KL5USB101 USB Ethernet driver
  • USB to network adapter MCS7830
  • NetChip 1080 based USB Host-to-Host Links
  • Pegasus/Pegasus II USB Ethernet driver
  • rtl8150 based usb-ethernet driver
  • SMSC95XX USB 2.0 Ethernet Devices

I wanted to go for the cheapest thing possible and found one on Amazon for $5 (including shipping). One of the reviews mentioned that it was DM9601-based, so I went for it. It took about a week to get here.
Once plugged into my USB hub, the Cr-48 detected it properly:
[ 8615.436387] eth0: register 'dm9601' at usb-0000:00:1d.7-6.1, Davicom DM9601 USB Ethernet, 10:13:50:xx:xx:xx

In fact, the ChromeOS interface changed a bit to reflect the new ethernet adapter:

In any case, if you're looking for a cheap wired ethernet adapter for your Cr-48, this works. I would have preferred to find a gigabit adapter, but it just wasn't worth spending that much money.

Note: Keep in mind the above adapter is USB 1.1, so you won't get more than 1MB/sec tops, if even that. It's good for basic connectivity, but that's about it. I'll be testing a USB 2.0 adapter here soon.


  1. The Nintendo Wii LAN adapter works, as well, and can usually be had for $5-$10 used, give or take, with a little searching. I used that for a week or two before I got my WiFi set up here for the CR-48.

  2. (Just to be more specific, that's the Rocket-Fish RF-GWII008.)

  3. That's good to know -- I'd heard this somewhere, but didn't really want to spend a bunch of money. I'll have to keep an eye out for one of those!

  4. I just bought an el-cheapo one from ebay for $4.77 shipped, could have ordered one from China for $2.89 shipped, but didn't want to wait forever. Anyway, I plugged it in to the Cr-48 and it picked up my network. I got 6 Mpbs from which is my download speed thru my provider.
