foxyloxley, you're right...at this point it's just shootin' in the dark and hopin' you hit somethin'...but I did come across an article where a modem caused a conflict with a mouse

PCMCIA Modem Causes IRQ Conflict with Mouse on NEC 3150 LT

in conflicts/sharing it lists the modem as IRQ 9 if that means anything

The Texan, howdy there partn'r, I did ask about drivers before and if I remember correctly the person said that because I do regular updates it should have come up there if I needed one...but I've still checked around and the only driver I can find is this one
