COM Ports are from Satan

Is it just me, or do you guys battle devices finding new com ports or losing communication with com ports on restart or resume from standby?

I have finally gotten everything wired up into my truck just the way I want it, but the CarPC is completely unstable (and unusable). 90% of the time I have to exit RR and fiddle with the GPS to get it connected (via bluetooth) and then share the ports via XPort. I also have a recurring problem with my Xenarc touchscreen controller coming up on a different port (meaning I have to go in and add another controller) each restart/resume. I'm using a serial to usb converter here that may be causing some of this trouble.

I wish there was a way to just lock the hardware down and disable "plug-n-play" so that XP wouldn't reassign com ports. Ideas?

I think this is the common theme with problems with resume from hibernate and com ports. I use a straightforward COM port and have never had any troubles.

I agree I always have problems with COM devices. Especially when I have true serial devices and those lazy *** USB wanna be real COM devices.... THey always argue and fight and I have to disable one to get hte other to work....

No kidding!! I thought I had everything working pretty good, and decided to mess with xport to split the GPS so I could use it for i-guidance and Roadrunner, and that has made my hair go grey as results seem totally random. I'm going to try a couple of more things and it they don't work I'm pulling xport off and keeping life simple. That is if I can get xport to shut down!
