Limitation
|
|
----------
|
|
The converter supports 'HID Boot protocol' only. This means it can host only standard USB keyboard(6KRO).
|
|
|
|
- Media/System control keys are not recognized.
|
|
- 'Fn' key itself cannot be remapped.
|
|
|
|
Many of NKRO keyboards still can work with the converter in 6KRO mode.
