This is not the same device that the original message complained about. Compare the vendor and product ID numbers with the dmesg log: [ 2.452110] usb 3-2: New USB device found, idVendor=0458, idProduct=0186 [ 2.452113] usb 3-2: New USB device strings: Mfr=4, Product=40, SerialNumber=0 [ 2.452115] usb 3-2: Product: Wired Mouse [ 2.452117] usb 3-2: Manufacturer: KYE SYSTEMS CORP. [ 2.458338] hidraw: raw HID events driver (C) Jiri Kosina [ 2.465370] usbhid 3-2:1.1: couldn't find an input interrupt endpoint In order to diagnose the problem, we need to see the "lsusb -v" output for the device that's causing the problem.
