Hello my dear friends! Let me just start with the fact, I'm a long time Windows user and I'm kinf of the OS X newbie. I've bought the Nokia AD-73 USB to LAN Adapter coz it was cheap. It's a common AX88772 chip, which is also used in Apple USB Ethernet adapter. The thing is, I can't install it - I must say it's working perfectly on Windows 7. I've found this: http://www.sustworks.com/site/news_usb_ethernet.html "If your device does not appear to be recognized by the driver, you might have to add it to the Info.plist file, which is located inside the USBPegasusEthernet.kext or USBAx8817x.kext directory. You can use the System Profiler or USBProber tool to find the corresponding Product ID and Vendor ID." So I've edited the file - copied one of the entries and changed the Product and Vendor ID. The thing is I think they're in string and they need to be integer. I've tried using both integer and string prefix but it's not working. Any ideas? I'm uploading the file, so you can see how I've edited it - I've only changed the file extension to .txt so I could upload it here.
