This device has an odd HID entry and causes a 10 second delay in boot. Add this device to the quirks list with HID_QUIRK_NO_INIT_REPORTS. [EDIT OUT THE FOLLOWING AS NEEDED IF EXPLANATION IS TOO MUCH, THIS LINE INCL.] dmesg shows the 10 second delay, which hinders normal operation (e.g., using the keyboard): [ +10.098394] hid-generic 0003:0409:042F.005A: timeout initializing reports Passing this arg to the kernel fixes the issue: usbhid.quirks=0x0409:0x042f:0x20000000 This patch expresses precisely the above quirk. See https://bugzilla.redhat.com/attachment.cgi?id=710695 for a similar case. For reference, here is the output of 'lsusb -v -d 0409:042f': Bus 002 Device 003: ID 0409:042f NEC Corp.
