I have a USB 3.0 Hub that I’ve had for several years that works fine under Windows and I could have sworn worked fine previously under various Linux kernels with this same laptop…though I can’t remember that last one it would have worked under. It is the Syba 7 port SY-HUB20078 - has 2 USB 3.0 ports and 5 USB 2.0 ports on it. My laptop is a Lenovo Yoga 730-15ikb.
I’ve just installed Manjaro, with everything up-to-date, and for whatever reason when I plug this hub in only USB 2.0 speeds are detected.
- USB3 devices do not work in the USB3 ports, dmesg doesn’t even display anything happening.
- If I plug a USB2 device into one of the USB3 ports on the hub it is properly detected as a USB2 device
- When I plug in a USB3 device into a USB2 port on the hub the device works fine, albeit at USB2 speeds
I’ve attempted various solutions such as use_both_schemes=y
and old_scheme_first=y
modprobe options suggested in a similar post, but no change. I’ve also seen other various kernel options such as pci=nomsi
and intel_iommu=on iommu=pt
suggested but those don’t seem to change behavior as well.
If I plug a USB3 device directly into the USB3 port on my laptop it is properly identified as a SuperSpeed (USB3) device. Listing of lsusb -t -v
