Dodgy USB pen camera

I bought a pen camera in Shenzhen while on exchange last semester. It took me this long to realise that it's dodgy - 2GB instead of 4GB. I tried recording a friend's thesis presentation but failed.

It appears as "company pmp platform opn usb" in device manager.

Setting the time - the microcontroller eats up the text file.

Create a file named "SystemTime.txt", with a single line in format
e.g. 2009-10-05 04:30:00
Then save it to the root directory of the spy pen. 

Reformat to proper capacity using low level format:
