My Raspberry worked fine until last month, now it doesn't detect ANY device. I tested it with a wireless keyboard and it doesn't work. I tested it with a basic keyboard and a basic mouse and the doesn't work. All these devices worked fine since last month. Also Raspbian continues to reset the raspberry on startup. NOOBS also continues to reset the Raspberry.

I think the internal USB hub is gone. Any chance to fix it?

    Have you tried a fresh install of the operating system? It might be a corrupted card. You can backup your existing files/settings by plugging the sd card into a linux/mac box and copying the files off.

  • To do this on a Windows computer, turn it into an .img file using win32diskimager and extract the data using a file manager such as 7zip.

  • Check your power supply. It looks like any device, even the internal hub, doesn't have enough power.

  • Just tried with a mac power supply (output: 2A) and it is the same thing. I will try with a new raspbian installation but i don't think is a os problem (raspian continues to reset with raspbian & noobs)
