Hi,
whenever I unplug an attached device to any of my 8 USB 2.0 ports on my
XP Professional sp1 (with all ms hotfixes and windows update patches) I
get a blue screen of death telling me that windows will start dumping
physical memory, even though I use "safelly remove USB device from your
computer". I have to reset the computer - there´s no other way simply.
I´ve checked device manager for conflicts but everything seem just
fine. This all started without me knowingly having had made any
software or hardware changes. Has anyone got a clue about this?
I have a P4 3,2 GHz P4P800-E Deluxe ASUSTEK I865PE, S478, 4XDDR,
USB2.0,RAID with 1024 Mb of RAM system.

Thanks for your help!

If doing an Unplug causes a BSOD then your USB ports/channels may
be experiencing a surge or spike. My first step to resolve would be to
update the Chipset driver package for the motherboard. You should
also check.
1.) Each USB Controller, Advanced (TAB) for % Bandwidth
2.) Each USB Root Hub for Power consumption

Ok! thanks! I´ll see if I can update the chipset or flash BIOS
possibly. Your next suggesting steps "1.) Each USB Controller, Advanced
(TAB) for % Bandwidth 2.) Each USB Root Hub for Power consumption "
Well I don´t really know here what you mean? How do I check bandwith
and power consumption for each USB Root Hub/Controller? Does one just
right click on the USB Root Hub/Controller in device manager and click
on an advanced tab?

System Properties, Hardware (TAB), Device Manager.

Each Root Hub can supply 500 mA (Half-Ampere) of current, shared
between all devices connected to that Hub. XP normally will "Trap"
over current states - but it's worth checking.

Bandwidth of each controller is also shared. The System will hold
in reserve a % of the available bandwidth. Some "Composite" type
of devices will consume a hefty share of a controllers bandwidth.
