[SOLVED] E7450: Problems with USB


Recommended Posts



I followed this guide to setup my E7450 and it works very well except USB ports. I use this EFI from forum and I dunno why it doesn't work. I will post my EFI folder here (only clover folder).

So, the problem is, everytime I plug something on USB it says: "USB accessory needs power: connect "usb dongle" to a USB port on this Mac". Only mouse USB works, but wifi usb and usb sticks don't.


If someone know solution, thanks in advance!
