Public bug reported: So,
My wireless Logitech keyboard with unified receiver is not working (again!) after installing the Vivid LTS Enablement Stack on Trusty, thus stepping up from kernel 3.13.0-65-generic to 3.19.0-31-generic. I got stuck at the LUKS-prompt, so I rebooted in text-mode (it works fine in the GRUB menu); when I removed the USB receiver and reinsert it, I get this output: [ 89.250799] usb 1-10: new full-speed USB device number 3 using xhci_hcd [ 89.380936] usb 1-10: New USB device found, idVendor=046d, idProduct=c52b [ 89.380957] usb 1-10: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 89.380978] usb 1-10: Product: USB Receiver [ 89.380990] usb 1-10: Manufacturer: Logitech [ 89.385703] logitech-djreciever 0003:046D:C52B.0007: hiddev0,hidraw0: USB HID v1.11 Device [Logitech USB Reciever] on usb-0000:00:14.0-10/input2 And nothing. Keyboard doesn't work. After rebooting to 3.13, this is what I can see in dmesg: [ 1.464976] usb 3-10: new full-speed USB device number 2 using xhci_hcd [ 1.483387] usb 3-10: New USB device found, idVendor=046d, idProduct=c52b [ 1.483389] usb 3-10: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 1.483390] usb 3-10: Product: USB Receiver [ 1.483391] usb 3-10: Manufacturer: Logitech [ 1.486128] hidraw: raw HID events driver (C) Jiri Kosina [ 1.490361] usbcore: registered new interface driver usbhid [ 1.490362] usbhid: USB HID core driver [ 1.492216] logitech-djreceiver 0003:046D:C52B.0003: hiddev0,hidraw0: USB HID v1.11 Device [Logitech USB Receiver] on usb-0000:00:14.0-10/input2 [ 4.966283] input: Logitech Unifying Device.

Wireless PID:4024] on usb-0000:00:14.0-10:1 It seems to me that the Logitech driver does not detect the unifying device or the keyboard correctly in 3.19, as it does in 3.13. This is not the first time this happens, there's a patch that has been applied and reverted several times, now it seems someone messed up AGAIN somewhere between 3.13 and 3.19.
