So, I have this cord (usb connector end of an Xbox 360 wireless game pad receiver) which was getting difficult, as in the receiver would only power on if the cable directly attached to the plastic usbA connector body was at a certain angle, which would suggest some damage inside the cord itself

And that ended today — not powering on at all in any position

I’m considering some #electronics surgery on the cord, just so I could possibly resolder the connector on a sane piece of cable but there’s this bulging thing 2 cm from the connector, which looks important but doesn’t leave much length to work with on my resold set adventure.

Anyone could explain what that round bit is, if it is important (I guess it is) and if I’m not taking on a too dangerous operation as a profane (ie would I risk making it more difficult to repair if I fail)
