I have a Gateway CX2610 tablet PC that works great and all, but I’ve been having problems with some of the USB devices that I have. I bought a USB hub so that I could plug the following devices all in at once:
– USB Bluetooth
– Microsoft Optical Mouse
– Printer
– Sound Blaster Audigy 2 NX External Sound Card
– iPod dock (Obviously I disconnect this when it’s not in use, but it doubles as an iPod radio for me, so it’s plugged in a lot)
– 250GB External Hard Drive
– VGA to S-Video adapter box
…now, two days ago, I bought the VGA to S-Video adapter box, and it worked famously. Just wonderfully. However, when it did work, I found that my external hard drive and printer did not; apparently, the S-Video adapter – which uses a USB port solely for power – took up too much power to allow my computer to recognize the other devices.
I screwed around with plugging some different devices in, and found that everything still works just fine if I only have 2 maybe 3 devices plugged in – but it seems there’s a significant power draw for this video adapter that I can’t offset. When I unplug just that, everything else seems to work alright, so, I need to solve this problem one of two ways:
1. Find another power source for the video adapter, or
2. Figure out a way that my laptop can give enough power to all of the devices.
Either will work. Seeing as how the second option would likely not involve buying extra hardware or a different kind of adapter, I’m leaning towards that one, but, well, how can I make it so that the amount of power going to the USB devices isn’t restricted, and that they can all work at once?
