Anyway, your suggestion above follows: #lspci -s 00:14.0 -v 00:14.0 USB controller: Intel Corporation 200 Series/Z370 Chipset Family USB 3.0 xHCI Controller (prog-if 30 [XHCI]) Subsystem: Lenovo Device 103c Flags: bus master, medium devsel, latency 0, IRQ 28, NUMA node 0 Memory at 43ffff10000 (64-bit, non-prefetchable) [size=64K] Capabilities: [70] Power Management version 2 Capabilities: [80] MSI: Enable+ Count=1/8 Maskable- 64bit+ Kernel driver in use: xhci_hcd # modprobe usbcore # lspci -s 00:14.0 -v 00:14.0 USB controller: Intel Corporation 200 Series/Z370 Chipset Family USB 3.0 xHCI Controller (prog-if 30 [XHCI]) Subsystem: Lenovo Device 103c Flags: bus master, medium devsel, latency 0, IRQ 28, NUMA node 0 Memory at 43ffff10000 (64-bit, non-prefetchable) [size=64K] Capabilities: [70] Power Management version 2 Capabilities: [80] MSI: Enable+ Count=1/8 Maskable- 64bit+ Kernel driver in use: xhci_hcd
