Portable usb data transfer device

[Happybobjr]

Ok i have had for a while now the need to be able to transfer files between two flashdrives without the ability to get to a computer.
finally i decided to see if anyone else had the idea and made something out of it.

Unfortunately yes.
Good news id, the only one i can find... well absolutely sucks....

I would like too understand what i would need to learn to get started in making something like this (but better)

What would i need to learn/know hardware wise?
What programing language would i need to know for this hardware (asm?)?

Note:  It would be nice to have not only usb, but also micro sd. although that can be done through a transflash so.. i guess not necessary.

Here is kind of what i would like for it to look something like:

best mp3 ever


any help would be appreciated, thanks



Note:  How can i tell if Belkin's patent on this devise is expired yet?

Well, more info would be nice . What device will perform the transferring? I'd assume a μC, but which would you choose? You'd also need USB hardware...
Sadly, I'm not much help here (never worked with hardware as much as I'd have liked), but I'll try

you see..... chances are, everyone here knows more about this kind of thing than I.

Two usb's at the end (female)
No left and right buttons i think.
μC?
Yes it will let you transfer files between the two.
Only transfers to the main directory.
Let you choose multiple files. stores the file directors in devise, then you can send all at once.  (like the ti-83+ series)
navigation of source's directories.
transfers any file and/or data.

μC stands for microcontroller
And... that's about all I can help with

No offence to the Omnimaga community, but the Cemetech forums might be of help.
There's some hardware geeks over there, notably KermM himself.
Your best bet is infamous BrandonW, who's the USB geek here.

For my input, I'd say go with a BeagleBoard for dev hardware. Use Linux on top of that and write the interface to handle the copying (and make it better with individual file copying!). The ARM processor CAN (and should be due to cost) be slower. Toss a touchscreen (or screen with buttons), and you win.

Of course, if you really want to challenge yourself, you can always implement the USB protocol, file reading, AND multiple file system management. (Assuming you use a non-ARM CPU, or any CPU that doesn't support Linux)

Yeah true, a lot of the hardware/modding guys are mostly there, as over here most people focus on calc games. BrandonW visits here sometimes, though, too.

ok, posted there
