djamiirr Posted January 14, 2019 Share Posted January 14, 2019 Hello Guys. I have macOS High Sierra installed on my Lenovo g50-80 laptop. At the beginning, everything was working fine, but recently, usb ports stops working suddenly sometimes when i replug usb device, wake up from sleep or by himself (no action) and the only solution is to reboot. lsusb shows that device still plugged when i remove it. I have USBInjectAll.kext in /S/L/E. how can i identify the problem? And thanks.
