That's my guess.

Wait... What who makes the PCB or what the board is/does?

The best answer is the exact device the board comes from. Next best is what the device does. But identifying the manufacturer isn't likely to be enough

signal amplifier

Come on, ya big sissies! Say your guess out loud! What's the point of hiding your guess under an md5?

Maybe they're really confident with their guess? I doubt it, though - I think this one is pretty difficult

a programmer??

Is it a USB amplifier. Can I guess more than one time?

Servo controller? Pc to Pc communication device? Motor controller? Signal analyzer? Debugging board. Amplifier. Relay? Port to port converter? Printer part? Scanner part? Micro controller?

Hero robot part? Computer part?

I'll take your most recent guess when the contest ends as your final answer. So I think your most current entry would be 'Computer Part'

It's an elecronic Rube Goldberg machine to entertain us guessing what it is.....

A USB network adapter

It looks like a USB keylogger to me.

That is a USB to USB copier used for duplicating flash drives or hard disks. People also call it a pendrive copier and many more things. This is basically a 1 to 1 duplicator and so it may not require a user interface. There are 1 to n duplicators available too with/without user interfaces.

Let's just hope I am right

It's a PCB with (what looks like) a microcontroller, some external logic, a clock and a couple of resistor ladders on board. If that IS a micro, it's in a socket, so it could be removed and programmed to do whatever you want.

It can also be a USB bridge,used to network two computers, also sold as a data transfer cable.

Some sort of USB protocol sniffer or converter.

Keyboard spoof? -- for planting phantom keystrokes, or translating one keyboard system (i.e., layout) to another.

It looks like an old USB inline Printer buffer

I think it is a USB data transfer device, such as used in USB data transfer cables.

I think it is a USB data transfer device, like the kind that are usually inplanted in cables.

It cam out of a Bay Router/Switch or AGL Switch same company Nortel Oh Duh I was looking at the wrong thing it came out of a CSU/DSU

a PS2 keyboard/mouse extender?

It will be hard to guess without knowing what the connectors are. And there may be other hidden gems on the other side of the board that could make it a whole lot more interesting (ie. attachment to a BlueSmurf/SD card socket, etc).

From what we can see, it uses a limited memory/capacity high speed PIC, and a high speed CMOS TTL Quad tristate buffer. It appears to be powered from J1. J1 and J2 appear to be the same. From the size of the socket it's either USB or PS2. It does not have any of the standard USB support chips. Though from my recollection of how USB works then the 125 handling the USB handshaking/ directional flow. But if it is then this is USB it's doing it the hard way. So one wonders why someone has gone to this much trouble. Either they were trying to do it on the cheap, or they are trying to tell the upstream host that the device is not what it believes it to be, or in some other way dicking with the data stream. The actual solutions could be quite specific and nearly infinite.

So it's definitely a finite probability generator with brownian motion detector for an infinitite improbability drive

It is a keyboard stroke recorder (datalogger)

OH OH! It's a THINGAMAJIG for telephones!

PS2 to USB Connector for connecting PS2 Keyboards and Mice to computers without a PS2 port

Okay - I am guessing again. It's a USB port extender using the power of the usb to re-condition the connection through the quad amp somehow. It's powered by the USB, and the pic chip only has 25 bytes of ram on it, so i't cant be a data-logger. Some type of 'media filter'.
