I noticed that this "method" reached the front page. I didn't want to speak out earlier for a variety of reasons, but people should be aware that the method as described in this and similar posts will most likely (99% certainty) not work. Basically, my knowledge of USB, the TI-LINK protocol, and the jailbreak in general all tell me this has a snowball's chance in hell.
1. SEND is meant to transmit variables, from strings to parametric equations, and it's unlikely the encoding used "over-the-wire" will resemble the raw ASCII-encoded bytes that is needed.
2. The Host must select interface 1 of the particular vendor/product id that is associated with the iPod. Then, a bulk transfer of the command must be completed on endpoint 2. Control, interrupt, or isochronous transfers cannot be used. It is unlikely SEND can embody all the nuances of that, or the USB interface in general.
3. Even if it did, "run rs" followed by a new line or carriage return is required. "RUN RS" is not going to work. It's the wrong case and doesn't have an end-of-line character.
4. MuscleNerd has one of these calculators and reported that program doesn't work.
That's not to say it is impossible to write code for the TI-84+ that will do the job, but a two line program in TI-BASIC is not going to do it, sorry. People have written working drivers for this calculator. Google for the usb8x project. I looked at the assembly API for the usb8x driver framework and it looks like it'll do the job. There's a BASIC API too but it looks too underpowered.
We may write code to do it from the TI-84+, but no guarantees. We have several other pressing projects that we're working on for the iPhone and iPod touch community.
