[geeks] USB and Windows 7 crashes...

[Lionel Peterson]

You've walked us down the path that leads to blaming the printer, so I'll go
with printer.

Check HP site for updated firmware and driver, the firmware may be the issue.

Check MB vendor for MB BIOS updates.

I suspect USB devices negotiate with bios on connection, and that negotiation
probably also occurs on power up, and may be going sideways.

I'd be interested in what happens when you plug in the printer as needed, do
problems start?

And what about adding printer after system is up?

Windows version? The way MS handles drivers has changed since WinXP...
