51 and version 4. Version 1 is found in "older" laptops and uses 4 bytes per
56 of up to 3 fingers. Hardware version 4 uses 6 bytes per packet, and can
58 4 allows tracking up to 5 fingers.
60 Some Hardware version 3 and version 4 also have a trackpoint which uses a
69 (TouchPadOff=0) will also disable the buttons associated with the touchpad.
99 By echoing "0" to this file all debugging will be turned OFF.
113 By echoing "0" to this file parity checking will be turned OFF. Any
114 non-zero value will turn it ON. For hardware version 1 the default is ON.
128 Sets crc_enabled to 0/1. The name "crc_enabled" is the official name of
133 verification is done by the driver on hardware version 3 and 4. The
138 "0" or "1" to this file will set the state to "0" or "1".
143 To detect the hardware version, read the version number as param[0].param[1].param[2]::
145 4 bytes version: (after the arrow is the name given in the Dell-provided driver)
164 Probably all the versions with param[0] <= 01 can be considered as
165 4 bytes/firmware 1. The versions < 02.08.00, with the exception of 02.00.30, as
166 4 bytes/firmware 2. Everything >= 02.08.00 can be considered as 6 bytes.
