Problem with USB ports..
Hi all,
I have a notebook with three USB ports. One for ADSL modem, one for USB hub with external power shared for a mouse and an external harddisk and the last one is connected to the same hardisk thru another cable (it needs two separate cables in order to get enough power).
I found with this configuration all the external devices worked great until recently I reinstalled Windows XP Pro sp 2 from the scracth, including all the necessary drivers from the original disks that came with my notebook. And the problem came when I connected the harddisk to the notebook, it didn't work. Desktop taskbar displayed message as if there's a power surge in one of the ports.
I have tried to connect to the devices via different port combination and also restart the notebook, but nothing seems to help. Any advice or assistance anyone can offer would be greatly appreciated. Thank you kindly.

See if a powered USB hub in between will help. That message sounds familiar, from someone else that I heard had a problem with USB after updating to SP2.

Hi all
Sorry for late reply, I had some deadlines that needs to be done, that was preventing me continue doing this stuff. Anyway, I have contacted my vendor and have some discussion with them. This is the conclusion: my notebook doesn't fully support USB 2.0, meaning not all ports able to have high speed USB connection. And my USB hub does not convert high-speed to non high-speed, as other USB hub. Thus, the problem. So I guess I have to make myself satisfied with this, at least for now.
Thanks alot for all the feedback.
