https://bugzilla.kernel.org/show_bug.cgi?id=208305 Bug ID: 208305 Summary: HID++ device behind a USB C hub fails to properly initialize Product: Drivers Version: 2.5 Kernel Version: v5.7.5 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: mcgrof@xxxxxxxxxx Regression: No I've purchased now about 3 different wireless mice, and they work gloriously if I connect them onto my laptop directly onto one of its USB C ports. Mind you the mice are USB, they come with a USB to USB converter. This works well, however if you run low on USB C ports you'll need a USB HUB. I've now tried two USB C HUBs, and when I connect the USB mice on the USB HUBs the device initialize and *sometimes* you get to finagle movement out of them but its clearly not working as expected. This should be easily reproducible with any HID++ mice connected to a USB C hub. This is what I get from a full journalctl -f output for example if I connect the mice directly to the laptop: May 29 21:02:15 phoebe kernel: usb 1-1: new full-speed USB device number 29 using xhci_hcd May 29 21:02:15 phoebe kernel: usb 1-1: New USB device found, idVendor=046d, idProduct=c52b, bcdDevice=24.07 May 29 21:02:15 phoebe kernel: usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 May 29 21:02:15 phoebe kernel: usb 1-1: Product: USB Receiver May 29 21:02:15 phoebe kernel: usb 1-1: Manufacturer: Logitech May 29 21:02:15 phoebe kernel: logitech-djreceiver 0003:046D:C52B.0030: hiddev0,hidraw4: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:00:14.0-1/input2 May 29 21:02:15 phoebe mtp-probe[8911]: checking bus 1, device 29: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-1" May 29 21:02:15 phoebe mtp-probe[8911]: bus: 1, device: 29 was not an MTP device May 29 21:02:15 phoebe kernel: input: Logitech M570 as /devices/pci0000:00/0000:00:14.0/usb1/1-1/1-1:1.2/0003:046D:C52B.0030/0003:046D:1028.0031/input/input64 May 29 21:02:15 phoebe kernel: logitech-hidpp-device 0003:046D:1028.0031: input,hidraw5: USB HID v1.11 Mouse [Logitech M570] on usb-0000:00:14.0-1/input2:1 May 29 21:02:15 phoebe mtp-probe[8925]: checking bus 1, device 29: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-1" May 29 21:02:15 phoebe mtp-probe[8925]: bus: 1, device: 29 was not an MTP device May 29 21:02:15 phoebe solaar[1995]: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed May 29 21:02:15 phoebe solaar[1995]: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed May 29 21:02:48 phoebe kernel: logitech-hidpp-device 0003:046D:1028.0031: HID++ 1.0 device connected.
