HID: usbhid: enable NO_INIT_REPORTS quirk for Semico USB Keykoard2
The device which identifies itself as a "USB Keykoard" (no typo) with VID:PID 1a2c:0027 does not seem to be handling the reports initialization very well. This results in a "usb_submit_urb(ctrl) failed: -1" message from the kernel when connected, and a delay before its initialization. It can also cause the hang the system. This patch adds the quirk for this device, which causes the delay to disappear. It is named as "USB Keykoard2" because the "USB Keykoard" already exists.
