That "hump" is an rf choke. it is a piece of ceramic material that has magnetic properties and is used to remove
 "spikes" or noise from electronic cables. Think of it as a chunk of refrigerator magnet that is not magnetized.
It is completely passive and has no electrical connections to the wires in the cable.

What are the pins of the usb connector? Which pins are usb and which pins are A&V?

I have a usb style connected from a non working av cable that I have been able to easily chop up to get the connector with the wires de-soldered. Ask if you would like photos of the connector.

It would be simpler if you just told us which camera model you have.

Oh right, I thought they were all the same. I have a SX260 HS.

I did a lot of searching but didn't find any particularity useful results. This looks like the answer: https://secure.flickr.com/photos/dunehaven/4094250604/

That would be the first search hit from the link I posted for you.   :D

The sx260 would be considered a "recent camera" so the picture looks about right.  You might want to ring out the connections end-to-end with an ohm meter to verify.  The USB and video connnections at the other end of that cable are pretty standard (and easy to find pin-outs with google).

@damcannon For what its worth, you can purchase the Mini USB plugs and make up your own cable.

Either use this sparkfun link or ... Ebay... search "10 Pin Mini USB Plug Male Socket Connector" (whichever actually matches the camera) if you genuinely need the bottom row of pins with the AV signals,  or search for "5 Pin Mini USB Plug Male Socket Connector" if you only actually require the standard top row of USB pins needed to make up a remote trigger of some sort. This will bring up numerous suppliers, expect to pay between 10 and 50 pence/cents/euro-cents each for the 5 pin types +P&P, more for the others, and they will be cheaper in bulk of course. 

Two problems remain, the first is that you need to be able to solder *very* small wires on to *very* small pins.
Pro Tip: Use *very* fine heat-shrink tubing and/or "pot" your completed connector with wax or silicone for a more robust finish. This will make it impossible to rework the connector afterwards, but will also make it *much* more robust.

The second is that you haven't quite explained why you need to know which pins are which... To make a USB remote, you only need to follow the many instructions in this thread, or elsewhere on this forum for cannibalising a standard Mini USB cable, this only needs the standard USB pins (you could also therefore use a 5 pin connector as I just suggested).
 
If however you have a genuine need to break out the AV pins for some particular purpose, then let us us know, as you have stirred my imagination.

One thing I have spotted is that with the 11 pin Cannon connector, you can effectively turn off the LCD to save battery life with a suitable plug. If you read the above link  from Google/waterwingz it states "To enable video output on cable and turn off LCD, connect Video Out Enable to Ground." In other words, linking pins 6 and 11 (with a 1k resistor if you feel scared) *may* switch of your camera display and increase battery life, this will theoretically work on *any* camera that has the AV pins populated, which I would imagine includes most of those where there is no optical viewfinder, and thus no way to switch off the display using the buttons. 

One other small point I would make is that there is no "standard" for these AV pins, (or indeed for overpopulated USB connectors in general) so for example HTC phones and the GoPro Hero camera seem to use entirely different configurations, so take care if you are tempted to try any modded Canon cable on a non-Canon device or any non Canon cable on your Canon camera.

Thank you for the advice. I have a non-working av cable from china which I got a refund for :). So I have been chopping up the £0 connector to make my own av + usb + camera screen enable switch adaptor. It is possible to remove the pins. I was easy to extract the connector. Unfortunately I dropped one of the av row pins and I can't find it  :o :( <bang head x10>. It doesn’t have an 11th pin. Does this mean this is a incompatible connector?

Don't order this one: http://www.aliexpress.com/item/Mini-Usb-Male-5-pin-To-3-RCA-AV-Male-Adapter-Cable-For-canon-Camera/640107165.html

That just stirred up the old grey cells, I was sure this topic had been discussed here sometime back..

http://chdk.setepontos.com/index.php?topic=6115.0

I will keep digging and see if I have more luck sourcing the 11 pin canon variant (as opposed to the HTC one which requires a bit of dremmel work, and removing the outer metal can to make it fit) More details of how this is done can be found here

Is http://www.kapshop.com/Rig-Parts-Other-Parts/c6_89/p274/Canon-11-pin-for-CHDK/SDM-and-Video-out/product_info.html# a diy connector were you solder the connectors if so the cable in the picture for show? Can one use all the pins or not? ie left,right,screen on/off, usb, etc.

Messaged the seller and got this reply:
Hi Alexander,

The cable comes as displayed. You solder at the end of the cables (one is CHDK, the other Video)
