Question

USB-Port (only) does not work with USB-Sticks

Hi,

I have an Early 2011 MacBookPro, 13''. Both USB-Port doesn't accept USB-Sticks any more - or I can not see it on the desktop or with the disk utilites. Directly booting from an USB-Stick isn't possible neither. It tried ten different sticks from different persons and from different apple owners. Really strange is, that all other USB-Devices, like keyboards, presenters etc. DO WORK at both USB-Ports. Lateley I did the High Sierra update, but I don't know exactly, if this was the "changer".

Any ideas?

Thanks

Waldemar

MacBook Pro, iOS 11.2.6

I started the disk utility and clicked on "first aid" (in german language there is only a button "first aid", no "repair" button). After that the usb stick still wasn't usable because I don't see the flash drive on the desktop neither on the disk utility.

This stick could be brocken. Use an different stick or use the Flash Card.

You get anew card or Stick for a couple €s/$s, so Sticks are not for longer use.
