I have broken my N900 USB for two times already during 2 years using, and now it's the third time going bad.

It charges without any problem from the regular charger, but when I connect it to PC, it will charge and work in mass storage only in certain angels (I put a book on a cable, where it connects to device), other way PC founds device but pops the message saying that device is not recognized, N900 also feels the usb but message pops up "not charging inefficient power".

Warranty has expired. Have to go to private work shop to get it fixed.

Soo fed up
