UsbHub not working on Ubuntu 18.04 LTS.
I have a notebook with only one USB 3.0 port and two USB Type-C ports.
I tried to insert a USB hub (I guess USB 2.0 hub) in the USB 3.0 slot, but Ubuntu did not recognize it.
Also I tried to insert Logitech k330 keyboard - same result.
But usb-flash that use USB 3.0 works perfectly on this slot.
[ 411.156178] usb 1-7: new full-speed USB device number 12 using xhci_hcd [ 411.284575] usb 1-7: device descriptor read/64, error -71 [ 411.521344] usb 1-7: device descriptor read/64, error -71 [ 411.629659] usb usb1-port7: unable to enumerate USB device
sudo vi /etc/default/grub
and changing to this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1 usbcore.old_scheme_first=1"
Am I missing something?
I don't think that the problem is with the hub, because on Windows 10 this hub works perfectly and the wireless keyboard too. I hope the problem is in configuration. I have Lenovo yoga with very ugly BIOS configuration. There are no buttons in BIOS to change USB settings.
Unfortunately I don't have a powered USB 2.0 hub. But I have a USB 3.0 hub. Today I tried to use the USB 3.0 hub. It's a Qilive USB 3.0 hub with 7 out USB 3.0 ports. This hub was successfully connected, but only 4 USB 3.0 ports were recognised:
[ 4694.376640] usb 1-7.4: new high-speed USB device number 16 using xhci_hcd [ 4694.401994] usb 1-7.4: New USB device found, idVendor=05e3, idProduct=0610 [ 4694.402000] usb 1-7.4: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 4694.402005] usb 1-7.4: Product: USB2.0 Hub [ 4694.402009] usb 1-7.4: Manufacturer: GenesysLogic [ 4694.403092] hub 1-7.4:1.0: USB hub found [ 4694.403535] hub 1-7.4:1.0: 4 ports
It's something like a power issue, but why are USB 2.0 devices not working if connected to USB 3.0 still unknown. And why on Windows are there no USB 3.0 or USB 2.0 issues?
Tried to connect USB mouse directly via USB 3.0 slot.
It didn't connect. But when I tried to connect USB mouse via USB 3.0 hub, It connects perfectly.
Something like I cannot plug USB 2.0 devices in USB 3.0 slot directly in Ubuntu... But if i connect USB 3.0 hub, and connect USB 2.0 device to this hub - everything works... Will be glad of any help.
