Hello, I'm using an MCB2140 kit and have the USB to dual-virtual com port software running on the LPC2148. On my work computer running XP the Host driver (PLP2KUS.inf) works great, but at home on my Vista laptop, (which I'm seriously thinking of downgrading!) the USB driver does not install. It complains that "The system cannot find the file specified", even though it found driver software. Not knowing a lot about writing device drivers, I wondered if there is a Vista compatible driver available for this example, otherwise I'll have to leave it for now. Thanks for any suggestions.
