After reading this, I think it is safe to say that the USB cable for the PSP is not the cure-all that many people once thought it to be.

So I got a USB cable for my PSP. What I want to know is - why did I have to? If it’s got wireless, why can’t I download music to it over that? I was able to download a patch for it, for Christ’s sake, why not a song?
Anyhow, the USB cable, a “Pelican Performance” model, didn’t actually work. Upon consulting forums I discovered others had the same problem. They solved it by getting a different cable. I decided to give the company the benefit of a doubt. They’ve got a nice looking website. Their motto is “Performance You Can Trust”. They have an automated customer support system. This is the response I got:

“To use the USB cable, consult your owner’s manual from the PSP. If you are still having trouble how to transfer data from your PC to your PSP suggestion would be to contact Sony’s at there 1-800 as this is a feature built into there PSP. Confirm that you have formatted your memory card. Thank you” [Read the rest]
