The problem may be that if you plug something into USB port 1, then later plug it into USB port 2, Windows doesn't recognize it as the same hardware that it already knows from before. Then, if you plug in a hub and plug the device into the hub, it's seen as yet another new piece of hardware. Same thing happens if you then plug the hub into the other port. The problem you then run into is figuring out which of the HP Photosmart C4200 printers you see is the one to print to.

snidely - thx - I bet that's why sometimes when I roll my mouse around the screen zooms in and out - I never knew why. I bet my cntrl key gets stuck at times. i know a few others do. time for a new keyboard I know. My son told me that last wk when he visited from out of state. He just shook his head at my keyboard. It's also missing a key or 2... I took some off to clean under them and lost a few... my E has the F12 'key' on it. that one had a piece break off underneath it... yeah, guess I'd better do that yet this wk before I'm caught without any keys that work. thx - I will try that (on purpose). lol!

I started out on the Florida Gardening Forum, then found this one, and I spend the most time on these two. I have visited others out of curiosity: Pets, Sewing, Natives, Garden Junk, Recipes, Cookware, and some others. I think all of them are of value, but Quilting on the whole has the most supportive people who are willing to welcome newbies and share their knowledge and at the same time are comfortable in asking for advice without feeling intimidated. I posted a question once on one forum about a certain type of conifer that I had just bought and was derided for only buying the common stuff found at the big box stores so I knew right away they weren't very welcoming of non-experts' participation. So it seems that there are some forums that only encourage expert participation which is fine if you're searching for an answer to a question but not too friendly for us unwashed people who don't know everything about everything! I'm with Rosa, life is too short for grumps and trolls.
