It's not the cheapest, but you could use something like this:

http://www.circuitsathome.com/products-page/arduino-shields/usb-host-shield-for-arduino-pro-mini/ <- $20
It's an arduino USB 2.0 controller, and if you hardwired a small USB hub into it, you could possibly engineer something out of it.
Topic: Portable USB 1:1 duplicator (Read 7147 times)
I'm interested in finding something like this as well, although not for dead drops.
I'm just a super sketchy guy

Not portable enough.
The two most recent links look like they would work, although the ports are on the same side, so using them on most dead drops would render the other ports inaccessible. Cords would solve this problem, but that seems less than ideal.
Have you considered making one?

I would make one, if a kit were available, say from adafruit.
So that I (or anyone else) can walk up to a deaddrop location with this device and a thumbdrive with a respectable amount of freespace, plug it in for a couple minutes, and take off without ever having to stand there with a laptop in the open. If the user wishes to place something on the deaddrop, he just turns the device around and uses his own thumbdrive as the source.
What about an Android phone with USB OTG support?

Might work, but I'm not willing to buy a new phone for this. I'd prefer a standalone device.

Could be perfect, but I can't tell yet.
Good find error, looks like it's also available here
Hm, now I get a 404 too.
Here is another option, though I think it needs some work and might not be appropriate for this particular project.

Something like this?
EDIT: Sorry, appears to be out of stock.. This site however reports to have one left...

Almost, but that device doesn't actually 'dup' anything, as the user is required to peruse the source device on the lcd screen and select files. Still, you did find one for sale, which is something I wasn't able to do. PM me your address, and I'll send you a nickel.
EDIT: according to the reviews, it also can't power a usb device and is notablely slow, so it wouldn't fit the bill. I want a device that can copy at full usb 2.0 speeds, as well as provide enough usb bus power to light up two thumbdrives. It's for this project...

I've been looking for this for a while, and even searching the makerspace type hardware hacker forums, and I can't find what I'm looking for.
I need a small, self-powered (i.e. batteries) usb drive duplicator. One source, one target. The device looks at the source and attempts to non-destructively copy the data found on the source to the target, if the target's data is older than the source and the target has enough space remaining. This is for the deaddrops project.
0.05 BTC to the first person that can pm me with a reference to wherever I can actually buy such a device or kit for such a device. I am the sole judge of whether your references qualify.
