3Com sold a USB Ethernet adapter especially for use with the Audrey. The model was 3C19250, and it's a straightforward USB adapter using the Kawasaki LSI KL5KUSB101 chipset. The Linksys USB10T, Netgear EA-101, and D-Link DSB-650C are similar. However, the Audrey won't necessarily support these other devices unless you reprogram their Vendor_ID and Device_ID values to match the 3COM device (0506 and 03e8, respectively). You can do this using Kawasaki LSI's "qttools" software.

Normally, the Ethernet adapter is noticed early in the boot process and dhcp is run to get an IP address. Otherwise, you can program the address manually in the system panel.

If you have a compatible USB device, you can manually set the Vendor_ID and Device_ID to match the 3C19250. Here's how:

  1. Download qttools.zip on a Windows machine
  2. Unzip the file and edit qtprog.inf and add a line to match your device. The Linksys usb10t uses this line:
%String29%=QTProg,USB\VID_066b&PID_2202
  1. Plug in the USB adapter and point it to the driver in the qttools directory
  2. Run macparse.exe and click "Read EEPROM"
  3. Click "Allow Change of Mfgr Info"
  4. Select "Keep new VID/PID"
  5. Change the Vendor_ID to 0506 and the Device_ID to 03e8
  6. Change the Product name to anything you like
  7. Click "Update"
