This post should be made a stick for all those n900 users still out there who have not yet experienced a broken usb and would like to prevent it from happening on their device.

Sadly for me is a bit too late now, as mine is now also broken!

So here is the solution:

Very simply, to prevent the usb from being pulled out, file down the latches in the actual microusb power cable side which is designed not to let go that easy and in turn is tearing out the microusb connector from inside the n900.
