Hi,

Please could someone help?

I have an Acer TravelMate 800 laptop which has 4 USB ports.

I have a Western Digital Passport external hard disk (320GB) and
whenever I try to connect this device I see the following error:

"Power Surge on Hub Port. The USB Mass Storage device has exceeded the
power limits of its hub port."

The device never appears in 'My Computer'.

I am prompted to disconnect the device and then click on 'Reset'.

I can connect a USB mouse in to any one of the ports and it works
fine. I can also connect a Kingston Data Traveller pen drive (512MB)
in to any one of the drives and that also works fine. It is only this
Western Digital Passport external hard disk which causes this error.

Can anyone help? Can it be resolved?

Any ideas most gratefully accepted.
 
The USB ports have a limited amount of current available. Disconnect devices
from other ports and retry the hard disk.

You should have cross posted this not multi posted. That way responses in
other newsgroups would have been visible to all the newsgroups you posted
to.
 
so you have a USB hub port attached to your pc?

what if you start w/o the hub and then attached the hub afterwards, do you
still get the message?? if so I Guess you will have examine which device
attached to the sub that cause the overload


assuming you have more than one USB port on your laptop, you may want some
the USB dev attached to other port. if the hup itself w/o device cause
overload, you will have to replace the hub. that is a usb device other than
hard drive can be inserted to the usb port w/o problem but the hub will
cause you trouble

USB external hard drive w/o it's own power supply/adaptor will take two
full usb port to run
