Help! Tasc. 122 Fried My Usb Ports! Options

[Philryan]

I just bought the Tascame US-122 yesterday, and it was working fine - sort of. i figured out that i needed to add power to my USB hub, since it wasnt powered already. after i hooked up an AC adapter to it, my computer will no longer recognice any USB device, except the US-122! My oxygen 8 will no longer power up or be recognized by my computer. My USB hub powers up, and my mouse lights up, but the computer wont recognize either of them. What's worse, is that my compuiter will no longer recognize my logic xskey! i am running panther 10.3.2 on a titanium powerbook G4 550mhz with an external HD. all drivers for the devices are fully installed. any help is very much appreciated. thanks all....

i have the kensington usb mouse, oxygen 8 keyboard, the tasc 122 and logic xskey....

i just had the moust and xskey hooked up to the unpowered hub and it was fine....

i plugged in an AC adapter to the usb hub to give it power so that i could hook the oxygen 8 (which needs power) to the hub. it worked for a bit, but then something went totally wrong.

system will no longer recognize ANY usb device except the tasc 122. i tried plugging everything in separately to the powerbooks usb ports, and they all power up fine but they still arent recognized. tasc 122 works fine tho? i reinstalled logic, then i tried reinstalling 10.3. nothing seems to work. i reset the pram and the PMU...still nothing? i dont get it.... all the devices light up and show power, but none of them will work?

i think maybe i surged the USB chain by adding the AC adapter to give it power? but why does the tasc 122 still work? i even reinstalled that driver....hrmmm...grrrr....i dont know what to do. so frustrated...

thanks for everyones help
