I've got a WUSB54G v. 4. I could use it well with it's bundled USB cable. I tried to use it with: 1. A 5 meter USB cable 2. A 5 meter shielded USB cable 3. Adding a 1.5 meter USB extender cable In 3rd experience I can see the Linksys Device in windows USB devices that takes 300ma power. But linksys monitor can't sense the adapter is connected, and says Adapter is not Active. With longer cables, adapter's power LED just turns on for a while and nothing happens next. Linksys monitor says Adapter is not Active Does anyone facing the same problem? What's wrong?
