I've been seeing stuff like this in the syslog from recent kernels: Sep 30 08:59:34 dorotea kernel: usb 1-3: new full-speed USB device number 3 using xhci_hcd Sep 30 08:59:34 dorotea kernel: usb 1-3: New USB device found, idVendor=046d, idProduct=c52b, bcdDevice=12.09 Sep 30 08:59:34 dorotea kernel: usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Sep 30 08:59:34 dorotea kernel: usb 1-3: Product: USB Receiver Sep 30 08:59:34 dorotea kernel: usb 1-3: Manufacturer: Logitech Sep 30 08:59:34 dorotea kernel: input: Logitech USB Receiver as /devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.0/0003:046D:C52B.0001/input/input18 Sep 30 08:59:34 dorotea kernel: hid-generic 0003:046D:C52B.0001: input,hidraw0: USB HID v1.11 Keyboard [Logitech USB Receiver] on usb-0000:00:14.0-3/input0 Sep 30 08:59:34 dorotea kernel: input: Logitech USB Receiver Mouse as /devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.1/0003:046D:C52B.0002/input/input19 Sep 30 08:59:34 dorotea kernel: input: Logitech USB Receiver Consumer Control as /devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.1/0003:046D:C52B.0002/input/input20 Sep 30 08:59:34 dorotea kernel: input: Logitech USB Receiver System Control as /devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.1/0003:046D:C52B.0002/input/input21 Sep 30 08:59:34 dorotea kernel: hid-generic 0003:046D:C52B.0002: input,hiddev96,hidraw1: USB HID v1.11 Mouse [Logitech USB Receiver] on usb-0000:00:14.0-3/input1 Sep 30 08:59:34 dorotea kernel: hid-generic 0003:046D:C52B.0003: hiddev97,hidraw2: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:00:14.0-3/input2 Sep 30 08:59:34 dorotea kernel: usb 1-3: USB disconnect, device number 3 Sep 30 08:59:34 dorotea mtp-probe[1544]: checking bus 1, device 3: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-3" Sep 30 08:59:39 dorotea kernel: usb 1-3: new full-speed USB device number 4 using xhci_hcd Sep 30 08:59:39 dorotea kernel: usb 1-3: New USB device found, idVendor=046d, idProduct=c52b, bcdDevice=12.09 Sep 30 08:59:39 dorotea kernel: usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Sep 30 08:59:39 dorotea kernel: usb 1-3: Product: USB Receiver Sep 30 08:59:39 dorotea kernel: usb 1-3: Manufacturer: Logitech The device is recognized, then something called mtp-probe comes along and blows it out of the water. The cycle repeats until either mtp-probe gives up and lets the device work, or the device itself gives up: Sep 30 09:00:10 dorotea kernel: usb 1-3: Device not responding to setup address. A workaround (found on the interwebs) is to add a udev rule in, say, /etc/udev/rules.d/99-mtp-no-probe.rules: ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c52b", ENV{MTP_NO_PROBE}="1" Now there are messages like this: Oct 2 10:18:09 dorotea mtp-probe[973]: checking bus 1, device 3: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-5" Oct 2 10:18:09 dorotea mtp-probe[973]: bus: 1, device: 3 was not an MTP device But so far nothing bad has happened. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
