 |
|
Hi,
`uname -a`:
Linux XPS13 4.9.7-gentoo #1 SMP Sat Feb 4 08:58:07 CST 2017 x86_64 Intel(R) Core(TM) i7-6560U CPU @ 2.20GHz GenuineIntel GNU/Linux
I have a USB thumb drive with dual ports. One usb 3 port, one use type-c port. When I plug it into the usb 3 port, my system can recognize it. But if I plug it into the type-c port, nothing happens. dmesg shows nothing. It seems the system does not recognize the usb type-c port at all.
I think I have missed some options in the kernel. But I could not figure it out.
I have also updated my BIOS to the latest.
Thanks,
David

Verify with "lspci -k" that all your USB controllers have a kernel driver in use.
Possibly your kernel is missing a driver for the controller which is connected to the USB Type C port. |

Sure, some kernel driver is missing. But which one? I have selected all I can think of. I do not want to enable all the kernel options...

You have this enabled in your kernel?
| Code: | Symbol: UCSI [=n]
Type : tristate
Prompt: USB Type-C Connector System Software Interface driver
Location:
-> Device Drivers
(1) -> USB support (USB_SUPPORT [=y])
Defined at drivers/usb/misc/Kconfig:270
Depends on: USB_SUPPORT [=y] && USB [=y] && ACPI [=y] |

To find the driver you need to know the device. There is good chance lshw marks it as UNCLAIMED. |

Yes, it is checked.
One interesting thing I just found. If I plug in the usb type-c drive in before I boot the system, the system can see the device and can access the content. But if I unplug it, then plug it back, nothing happens. Apparently, the system only try to detect usb type-c device during boot. But why?
