Since then, everytime I connect either the printer or the Ipod, the blue-screen happens, same error code. However, I can use the linksys VOIP and nintendo charger fine.
The Ipod was able to be ressucitated using another laptop and works fine - so is not a device issue. Printer also can be used by other laptop.
Prior to troubles I had reinstalled XP and SP3, and done all the updates that Dell and Windows advised. Am using BIOS A38.
I have deleted and re-installed all the drivers, there are no yellow exclamation marks at all.
I thought it must be something to do with the power in the USB ports, however I bought a USB PCMCIA card with external power, and the same issue happened.
I wonder if this is a USB1.1 vs. 2.0 compatability issue, but my hardware is so standard that I cannot believe the SP3/Dell updates have not already dealt with.
Any help most gratefully received.
