If you had only 2 USB ports, was your other Keyboard plugged into one, or do you have 2USB's and 2 PS2's for hook ups? If you only have 2 USB's and no PS2's then by all means pick a USB HUB and that will add the extra ports that you need. To find a USB 2.0 hub with A/C plugin they might have them at Office Max and Staples and all over, probably even Target. I assumed that when you stated the new keyboard had a USB connection and both were in use...that therefore the older keyboard was connected by a PS2 connection (because if the older keyboard had been disconnected from one of the two USB ports... one would be available). Or did I presume too much...again? Below is a nice example of an electrical plugin/usb plug in at Amazon. Although I can't figure out what those four pegs stuck on top of the box are supposed to be on the picture from a owner. Some hubs just plug into your computer and thereby draw extra electrical energy through it. The better ones plug into your computer but come also with an A/C plug to get the energy needed to run out of a wall socket, instead of drawing the extra through your computer. Just as TomH had suggested. The boys from along time ago made the same suggestion to me with my notebook and they are right. Its looks like Bob14 found your two hidden USB ports! None-the less you will probably want a hub sooner or later anyway. Between speakers, mice, keyboards, printers, external hard drives...and OHYEAH Game Pads!...they fill up fairly quickly. Bob14 a nice guy. He's fun too. marf Here is a link that might be useful: D Link AC plugged 2.0 USB Hub

Update: I bought a new cable at Radio Shack. Went to download the driver, found out that NOOOO!!! HP did NOT have the drivers available, for ANY recent Windows systems. Come to find out, the page that was set up with links for downloading the applications was bogus, when you clicked on the link, you got a whole page of information, but bottom line, the drivers weren't available for downloading and hadn't been since 2009. This INFURIATES me!! My Laserject 5L is completely useless now. And no, I don't want to mess around on E-bay trying to find and install this or that for my old laptop. I can't even get the printer to work with the old laptop which has a prong cable connection. The print job goes to the printer, the printer turns on but never prints. Eventually I get an error message. So I don't know what the problem is. I have uninstalled and reinstalled the driver from the computer over and over again, so maybe there is something wrong internally with the printer. My PC guy told me I could get a pretty good laser printer for 100 bucks, and when all's said and done I would probaby have to spend over 100 bucks messing around trying to fix the old system, with possibly no good results anyway, so I'm giving up on my old 5L friend. I am NOT very happy about it!! :(

the easiest way is to simply go buy a cheap little usb 2.0 multi port hub and get a usb cable hook one end to your pc usb port and run it up to the top of your desk and plug in the usb hub so you have easy access to it and you will have several more usb ports right there on your desk. that is what I do I have one on each of my computers on my desk so no bending and reaching for the ones on the tower. Or you can go buy a usb card and install it into the computer it is fairly easy to do. I have bought several 4 port USB 2.0 hubs at Big Lots for $6 each and they work great. You just want to make sure the ones you get are 2.0 so they will be faster. below is the link to a product search at newegg for usb hub so you can get an idea of what is out there, the ones I use are just usb powered so do not have a power plug in but you can get ones that have a power plug in also if you need it to have extra power. this is a link to a usb card search ENCORE 5 Port USB2.0 PCI Card Model ENLUSB2-5PCI-BR - Retail Here is a link that might be useful: usb hub

My gut reaction is that Verizon was too lazy or cheap to write the drivers for their product. As I read it, the Multi-WWAN driver is for devices that have wireless broadband hardware built-in. I'd download the HP Multi-WWAN driver for a similar mini (make sure you get the matching O/S). Either the driver is going to install or it's going to balk at the lack of necessary hardware. I'd bet that even if it balks, the drivers get installed anyway. If that doesn't work, I'd call Verizon and ask them to support their product. You're paid them for the device and continue to pay them for monthly access. HP Mini's are quite popular so you can't be the only person having this problem.
