The end result of the project (and yes, it works. well, one of them does. I actually did this mod to two keyboards, and one of them does work - the other one I'm still fixing.)
These new mini USB buttons are gorgeous - full bleed print (optionally on both sides - from USB2U.co.uk
I love the abstract feel of this macro image.
A client brought me a broken 1 Gb USB pen drive containing data. A lanyard attached to the USB key was violently pulled out of the USB port, pulled upwards and quickly. This not only bent the circuit board (which has since been straightened) and pulled the solder pads connecting the USB connector the the board, clean off.
This left nothing to solder to. From here, I used a 20x magnification to track the pads to hairline copper tracks and scrape of the insulation ready to have very thin wires (which dwarf the tracks) soldered to them.
As I did not want to heat up the memory chips too much, I soldered the USB connector to wires, the circuit board to wires and then joined the wires. I ended up soldering 4 data pins and two ground points.
From here, the USB key worked and I extracted 300 MB data.

USB to UART converter based on the FTDI FT232RL. Includes UART connector, AVR ISP interface, breakout, push-button switch and LED.
The UART socket is compatible with FTDI cables, and the Sparkfun Basic adaptors. The logic-level can be set to either 3.3V or 5V. The supply voltage for the external connectors can be set independently to either 3.3V or 5V. An on-board 3.3V regulator can supply up to 250mA to external devices. All connections from the FT232RL (except OSC1 and OSC2) are broken out to pads spaced on a 0.1" grid.
LEDs indicate when data is transmitted and received. A third auxiliary LED can be controlled by the DTR output. The state of the switch can be read by examining the CTS input.
Component footprints are enlarged to allow for easy hand assembly, reflow not required.

Lovely example of our small premium white gift box with custom cut foam - shown with our wooden USB flash drive
This is a USB wristband with a twist - its got "tread" built into the design so that it looks like a classic Goodrich tyre!!
Without the black wire connecting the outermost pins, the camera does not shut off its LCD and output video through the 11-pin USB port. See here for an end-on view.
