I have the USB conversion kit; but don't have the equipment or expertise to de-solder the resistor on the MB.
Anyone willing to have a go?
The resistor is about the size of half a pin head!

its most likely fixed with conductive paste, it was also pik+placed by hi tech tooling
you would be mad to try and use a soldering iron,
but intregged as to what use the usb conversion will do

You could use a 15watt Antex soldering iron with a very narrow 2.5mm head + "SODER WICK" (GOOGLE IT)Size 1 approx 2mm and a steady hand.....
or have a read here:

I use a hot air head gun with narrow tip to do work like this but rarely these days......

if its a smd resister you want to remove , any soldering iron will do , heat some solder onto the the tip untill you have a blob big enough to cover the res , this will melt both sides and then just slide the res away .

Quote fro the guy wot makes the USb board:-
The Dreambox 500HD can be modified to enable USB connection by removing a resistor R1011 and R1010 (if present) on the main board. There is a good description available thanks to the Dream-Elite team.
However, the USB connection is disabled intentionally because the power supplied to the USB connection is not current limited as the USB specification requires, so using the USB connection without this could be harmful to your Dreambox. I have made a small PCB that includes a fuse, a current limiter with microcontroller, an internal USB connector to attach a USB flash memory internally and a header to attach an external USB connection to the rear of the DM500HD (which is already prepared with a cutout for a USB connector). Note that you still need to modify your DM500HD according to the above instructions to remove the resistors on the main board to enable USB.
Note that modifying the Dreambox 500HD in this way clearly voids your warranty and that I am not taking responsibility for any damage that could be caused because of this modification. The PCB I have made is made to improve the security of the USB connection, but I can still not guarantee that there couldn't be any damage done under certain cir***stances even with the PCB in place. I am using an internal flash memory and an externally powered 1.5Gb USB harddrive without any problems though.
