I have the latest drivers for my modem, so that's not the issue. I tried that following some guy's advice
Unplug all of your USB devices then replug the cable modem via the extender. If it is now recognized/working, your USB is power saturated and unable to provide power to the USB extender with all of the other USB devices enabled. Get a powered USB hub and put it in-between the computer and the extender.
didn't work. I don't think it is a power issue since the modem worked at first, it just won't work anymore. I've only had this cable for about a day and like I said, everything but the modem works with it.
What's weird is, when I first started having problems with it, the computer kept trying to detect what was on the other end of the cable. Eventually it said "drivers installed" and asked me to restart my PC. Since then, whenever I plug the modem via the USB extension cable, it instantly tells me that the USB device has malfunctioned. It is as if the PC has already decided it won't recognize the Modem plugged via the cable.
