Dave, if i take a usb cable from a psp and a dsl cable and I cut them both in half and connect the usb to the dsl cable would that make my Internet work on my Sony PSP? I have firmware version 2.70.
Oh, there are so many reasons that your idea is wrong, but let me state right up front: don’t do this or you’ll fry your PSP and possibly your DSL modem too. Okay, I feel better now.
If all electrical wires and data wires were really like the plumbing in your house, your solution would be a novel and ingenious one. Unfortunately, it’s not water flowing through whatever pipe and connectors you can hook up, it’s electricity, and that has an infinite variety of different voltages and frequencies. Get it wrong and either your device simply won’t see the electrical signal (imagine connecting your power cord to a 9 volt battery rather than a 110 volt wall outlet, for example) or it’ll be more than the device can handle and you’ll quite literally destroy the device.
There are yet other problems with what you suggest too: more likely than not, your DSL modem connects to a computer via an Ethernet cable and when you say “a dsl cable” you’re probably talking about a cable that’s actually comprised of 8 or more active wires, each sending a different signal at, possibly, different voltages. USB, however, only has five wires: four ‘pins’ inside the USB connector and the outside itself, which I’m guessing serves as a shield more than anything else. Different number of wires = big problems.
But there’s a bigger problem with what you suggest, even if you could figure out a junction box or connector that would let your DSL modem speak USB directly (and some do, to be fair): the Sony PSP cannot connect to the Internet via USB.
That’s right, you can’t do it anyway.
I get questions from people asking if they can ‘piggyback’ off their existing Internet connection by hooking up their PSP to a PC via USB and while they can definitely access files, copy movies, etc., there’s no way that I have heard of that lets you instruct the PSP to look to the USB cable rather than wifi circuitry to find an Internet connection.
Thanks for the darn interesting question, though!
