Description Colin Lord 2017-12-26 02:46:58 UTC
I have a Corsair K65 keyboard which does not function without adding a USB quirk similar to that of the K70 or K60, such as bug #193279. I have resolved the problem on my system by adding this line to my loader.conf:

hw.usb.quirk.0="0x1b1c 0x1b07 0 0xffff UQ_KBD_BOOTPROTO"

  Improve USB gaming keyboard support.

  Add support for decoding pressed keys as a bitmap. The keys in the
  bitmap are described in the interface specific HID descriptor. Some
  keyboards even have multiple input interfaces, only using the bitmap
  method when the event array is full. That typically means when more
  than seven keys are pressed simultaneously.

  The internals of the USB keyboard driver have been slightly reworked
  to keep track of all keys in a single bitmap having 256 bits. This
  bitmap is then divided into blocks of 64-bits as an optimisation.

  Simplify automatic key repeat logic, because only the last key pressed
  can be repeated.
