My computer does not recognize my phone when connected to it. The weird part is that it did yesterday.

What I have tried:

  • uninstalled USB drivers
  • uninstalled Samsung drivers
  • reinstalled Samsung drivers
  • updated chipset drivers
  • checked Android settings
  • unplugged PC for 30 minutes (possible solution found online)
  • multiple reboots of both computer and phone


The only thing different were the Windows updates I finally installed this morning, but none of them has anything about USB that I could find.

Any Idea?

Does Device Manager recognize anything at all?

Check your USB connection settings on your phone as well - make sure it's set to MTP.

What times my comp even senses it Device Manager lists it as "Unknown device" under Universal Serial Bus controllers.

Phone settings hadn't changed, but I have tried it on all of them while troubleshooting. Currently set to MTP, though.

EDIT: OK, that is weird as hell. On a lark I unmounted the SD, removed it, inserted it, and remounted it. While I had the back off I lulled the battery and then rebooted. BAM! It started working again. I had already done all of that before. I guess I wasn't holding my mouth right or something.

I had that same issue with my iPhone, My issue turned out to be a bad wire from the phone to the PC, worked some times but not others, One time it wasn't working but did sense something was attached and I bumped the wire and it suddenly started working so as if played with the wire it would disconnect then re connect on and off, Got a new cord and all is good.

It usually happens when the port of your system not working properly or sometime the device is not supported by the drivers etc
