If you're using an older machine don't bother trying to 'update firmware' cos you may brick your machine if you're unfamiliar with that.
Personally I think it is how firmware is managed and it's quite possible that the drivers you have for your hub are out of date with current Ubuntu firmware. They sometimes get out of sync with the central repository. I've had this problem on other distros like Linux Mint. But if i connect USB 3.0 hub, and connect USB 2.0 device to this hub - everything works. Something like I cannot plug USB 2.0 devices in USB 3.0 slot directly in Ubuntu.
mousenotebookīut when I tried to connect USB mouse via USB 3.0 hub, It connects perfectly.
Tried to connect USB mouse directly via USB 3.0 slot. And why on Windows are there no USB 3.0 or USB 2.0 issues? It's something like a power issue, but why are USB 2.0 devices not working if connected to USB 3.0 still unknown. usb 1-7.4: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-7.4: New USB device found, idVendor=05e3, idProduct=0610 This hub was successfully connected, but only 4 USB 3.0 ports were recognised: usb 1-7.4: new high-speed USB device number 16 using xhci_hcd It's a Qilive USB 3.0 hub with 7 out USB 3.0 ports. Unfortunately I don't have a powered USB 2.0 hub. There are no buttons in BIOS to change USB settings. I have Lenovo yoga with very ugly BIOS configuration. I don't think that the problem is with the hub, because on Windows 10 this hub works perfectly and the wireless keyboard too. usb usb1-port7: unable to enumerate USB deviceĪnd changing to this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash tosuspend=-1 usbcore.old_scheme_first=1" usb 1-7: device descriptor read/64, error -71 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.Īlso I tried to insert Logitech k330 keyboard - same result.īut usb-flash that use USB 3.0 works perfectly on this slot.ĭmesg result: usb 1-7: new full-speed USB device number 12 using xhci_hcd I have a notebook with only one USB 3.0 port and two USB Type-C ports.
