Hello,

I am having this problem with Vista 64 bits and an HP dv5t laptop that came
with the OS pre installed.

When I plug in USB devices such as USB thumb drives, or even USB external
hard drives (which have their own energy source) the computer completely
freezes. I have noticed this always when the computer has resumed from
hibernation. I can plug in the devices after a fresh boot and they do not
cause any problem.

Also, if I plug in the devices BEFORE resuming form hibernation (when the
laptop is completely turned off) and then resume, the devices work OK and
the system often does not freeze. Sometimes it freezes when it's 99% in the
process of resuming. However, in those instances, I simply force a shutdown
with the power button, then power on the laptop, Vista tells me that a
previous resumption attempt failed, I instruct it to reattempt and the
laptop resumes without freezing.

I have run Windows Update and the laptop is up to date. The HP health
monitor also is run frequently and does not find any updated drivers. Has
anyone else experienced this?

Thanks in advance
