I wouldn't even do that, i'd get an IDE cable and hardwire it to a USB cable, plug the stick in there. The IDE supplies the same voltage and plenty more current than what the USB stick would need.
Good luck to you with that.
Well thanks I guess. Was that slightly cynical or was ya honestly wishing me good luck? C'mon now lil buddy, I ain't messin' with you, I swear it's that easy, i'll do one today if you like, and be the test monkey.
I guess it was a little bit off ......... you did not explain how you were going to join the data wires from the IDE to the USB for instance ...... the devil is in the detail .. some 40 wires to 2, which are discarded, joined together, passed through components etc ........ without which no assessment can be made of the theory.
Okay, fair enough, but the reason I didn't provide that detail, is because I haven't ever done it, I would still need to figure out details, but the system in question is really not in the least bit complex, only 8 wires to deal with on the USB side. Forgive me fer bein' a little cocky, but I am from Texas, and we always believe from the get-go that a thing can be done, and that we can do it.
I didn't say it is impossible, but would I attempt it?
Nope. Too complex versus the cost of achieving a similar result the other way.
Using a premade device all the necessary connections are made internal to that device.
Gets rid of all the complexity.
BTW, I have no idea what kind of USB devices you have, but there are only four connections on mine and two of those are power, leaving two for data. I guess wires in the cable might be doubled up for more flexibility, giving eight.
In any case, it is not impossible, but it is not easy or quick to do what you describe.
So if you do undertake it, good luck with it ...... I reckon you would need it
