Correct. |

Old Intel host here. No lock-ups but I had also USB-related problems |
| 18 |
with 4.12 till I set this (new) option in kernel config: |
| 19 |
|
| 20 |
CONFIG_USB_PCI: |
| 21 |
A lot of embeded system SOC (e.g. freescale T2080) have both PCI and |
| 22 |
USB modules. But USB module is controlled by registers directly, it |
| 23 |
have no relationship with PCI module. |
| 24 |
|
| 25 |
When you enable the above you get the next one: |
| 26 |
|
| 27 |
CONFIG_USB_UHCI_HCD: |
| 28 |
The Universal Host Controller Interface is a standard by Intel for |
| 29 |
accessing the USB hardware in the PC (which is also called the USB |
| 30 |
host controller). If your USB host controller conforms to this |
| 31 |
standard, you may want to say Y, but see below. All recent boards |
| 32 |
with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX, |
| 33 |
i810, i820) conform to this standard. Also all VIA PCI chipsets |
| 34 |
(like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro |
| 35 |
133) and LEON/GRLIB SoCs with the GRUSBHC controller. |

The first option's help line is a bit misleading, my system is not an |
| 38 |
embedded one but without UHCI I don't have any USB working. In 4.11 and |
| 39 |
earlier USB_UHCI_HCD was not tied to USB_PCI and that's why make |
| 40 |
oldconfig messed up in my case. |
