Thanks for all the replies, i almost thought that this was an dead community and thought "i'll post something here, check back in a week and see if i at least get one reply" Talk about getting proven wrong :P
Well i looked into this app called usb8x, but from what i gather it is meant to be between the calculator and a input device (mouse keyboard ect.) only, thus not working with a computer.
i checked out Brandons website, he seems to be THE TI-hacker. looking through his archive i found something cool called periph8x
now, this part about pretendin to be a keyboard (witch i understand is the biggest part of this hack) is not important, but to send data at all, possibly to an application running on host pc.
So Graphmastur, i think your concept/idea is the one that suits me best… just dont get what guide you are talking about…
