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!! :(

Intersting Jean, because that's the kind of flash drive I am using, (a Cruzer one). I haven't used another kind yet, so will have to experiment. Yes, it is an interesting comparison to other appliances I have around the house. Like a coffee maker for example, that has a green light for on. It is OK to unplug it while the green light is on, but it still means the device is "on" which to me says the program that supposedly disengages the flash drive doesn't work. It would be like having the "Off" button broken on your TV. Yes, if you wanted to turn off the TV you could uplug it and then plug it in when you wanted to turn it on, same with a lamp or something. Like I said, I'm not worried per se, just curious as to what is going on inside the computer.

I can't answer your question, but here's a link to a TIVO forum that might be able to tell you. You could also enter USB in that forum's search feature and possibly up with an answer. If that doesn't help, there's also another forum run by TIVO where you could ask. Here is a link that might be useful: TIVO

The 2.1 amp rating, while not clarified in the specs, usually is a combination of the total of the two USB connectors, which may be often be asymmetric - .5 amp on one, and 1.6 amp on the other. You need to look at the charge requirements of the devices you are plugging in to the USB charge ports. A cellphone can charge off a low current supply but a tablet requires a much higher current availability to charge as quickly. The device connected to the USB port determines it's rate of charge, regulates it, and is only limited by the supply current available to it - the available current is only a "limiting factor" and it does not force the charge rate to be any faster. Part of all this conundrum is that the USB port was never designed to serve as a "charge source" but to just to simply supply current to slave devices connected to the USB port. But then manufacturers soon found they could eliminate the cost of a wall-wart transformer by making it "USB rechargeable". You might also want to look at the "plug in" type devices that provide a feed-thru for AC and USB ports for charging - being external they can often provide better heat sinks and current availabilities.
