    Somebody gave me a G4 Cube 500 Mhz/256/20GB/CDRW/Ethernet/Modem. The cube able to boot up, I can see the installed Mac OS 9.1, but it can't detect any device that hooked up in USB port 2. And yes, there is a problem with USB port 1, the pin inside crushed, and the jack is missing.

    Is there a way to fix this problem? I want to have this Cube working with USB port 2 only, and I've tried to use different mouse/keyboard and still the machine doesn't recognize the device. Please Help. Thanks.

    Can you see the USB ports in Apple System Profiler?

    It gave the logon screen, but I can't to do anything, since it does not detect the keyboard/mouse.

    Ooops....It appears that putting two and two together this AM ain't working all that well.

    I can't think of anything other than replacing the logic board. Should be ~$200 USD.

    Sounds to me like you simply abused the ports too much...

    I think the USB controller is b0rked. Anyone else?

    In any case, new logic board for you!

    He doesn't say if he's got the Cube speakers, but they won't work plugged into a hub (yes, I realize he's got bigger problems...).

    It's also possible that the damaged USB connector is shorting out the USB bus, in which case the hub on the ADC monitor probably won't work either.

    You right, if his USB connectors are fried then it probably fried the USB Bus, so the monitor would not work.
    Try and find a used logic board, that is your best bet.

    I said that... :p

    Used logic board is the only way to go. And while you are taking the Cube apart, you might as well upgrade the processor, hard drive, and optical drive. Add a fan, too.

    Thanks for all the responses and helps, and it looks like a lot of work to be done when replacing the logic board which cost $150-200 on eBay. Thanks guys.

    Like the man said, go to Cubeowner.com. There's a huge FAQ about all things Cube and if it ain't in the FAQ, someone's probably asked about it in the forums.

    Using the USB ports off an ADC monitor is also a great idea, if you know someone who has an ADC monitor you could just do a test with theirs.
