Correct. Old Intel host here. No lock-ups but I had also USB-related problems with 4.12 till I set this (new) option in kernel config: CONFIG_USB_PCI: A lot of embeded system SOC (e.g. freescale T2080) have both PCI and USB modules. But USB module is controlled by registers directly, it have no relationship with PCI module. When you enable the above you get the next one: CONFIG_USB_UHCI_HCD: The Universal Host Controller Interface is a standard by Intel for accessing the USB hardware in the PC (which is also called the USB host controller). If your USB host controller conforms to this standard, you may want to say Y, but see below. All recent boards with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, i810, i820) conform to this standard. Also all VIA PCI chipsets (like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro 133) and LEON/GRLIB SoCs with the GRUSBHC controller. The first option's help line is a bit misleading, my system is not an embedded one but without UHCI I don't have any USB working. In 4.11 and earlier USB_UHCI_HCD was not tied to USB_PCI and that's why make oldconfig messed up in my case. bye, raffaele
