Specifies the maximum number of times Windows 2000 polls the hardware. If the number of trials specified in this entry is exceeded, Windows 2000 stops polling. This entry is used on keyboards other than old-style AT keyboards.

You might consider increasing this value if the driver does not initialize or operate correctly and the System Log in Event Viewer contains the following message from the source, i8042prt :

The operation on <driver name> timed out (time out is configurable via the Registry).

Unlike some entries in this subkey, this entry remains in the Parameters subkey and is read from this location even after a keyboard is installed.
