usb-c hub only works in one port (HDMI)

nerydlg · January 31, 2018, 5:59am

Hey guys,

I got a xiomi notebook pro, and it came with 2 USB-C ports. I bought a usb hub with an HDMI output, but this only works in one of 2 usb-c ports, however the port that works is the charging port. I already looked for the same issue in google, but I didn’t find anything. I hope you guys could help me.

here is the link for the computer (just in case you need to check the specs) https://www.gearbest.com/laptops/pp_786412.html?vip=4264809&gclid=Cj0KCQiAzMDTBRDDARIsABX4AWzMVP0sEJLdMmC4lhVoHK2GZ41F8FGqvqebv-HJOOdYUmZ0w0qVvLIaAsBaEALw_wcB

here is the output of lsusb:

here is the output of dmesg: (that works)

Welcome to openSUSE Forums nerydlg. I note that the main difference with the failing port is the following output (where a device is detected a low speed device)
but this doesn’t seem to be related to the Genesys hub device…

 3128.439354] usb 1-1.1: new low-speed USB device number 41 using xhci_hcd
 3128.440176] usb 1-1.1: Device not responding to setup address.
 3128.648294] usb 1-1.1: Device not responding to setup address.
 3128.855521] usb 1-1.1: device not accepting address 41, error -71
 3128.856019] usb 1-1-port1: unable to enumerate USB device

I do wonder if this is perhaps due to a power limitation with one of the ports perhaps? I’m still coming up to speed with these USB-C ports, but maybe this wiki page will help clarify further…

Reading a bit more, it may be that the other port does not support alternate mode, required to provide display port and HDMI output…

https://en.wikipedia.org/wiki/USB-C#Alternate_Mode_partner_specifications

Alternate Modes are optional; USB-C features and devices are not required to support any specific Alternate Mode. The USB Implementers Forum is working with its Alternate Mode partners to make sure that ports are properly labelled with respective logos.[36]](https://en.wikipedia.org/wiki/USB-C#cite_note-41)
Alternate Mode hosts and sinks can be connected with either regular full-featured USB-C cables, or converter cables/adapters:

Thank you for you quick response deano_ferrari.
I already checked the links and I have only one more question. there isn’t nothing to do to add display port support since, as far as I know, this is added in hardware. that’s correct ?
I’m asking because I’m not completely clear about if this could be added by a configuration or something like that.

sorry if those are fool questions
