disabled by default in the hub. This step can be skipped either if the hub
feature controller is enabled by default or hub class filter driver is already
installed. Refer
3. Find out the hub index by executing the command "pt2main.exe /l". Refer

programming if either HFC is enabled by default or hub filter is installed as

configurations.
>pt2main.exe /pspi < firmware_filename.bin> /id <index>
-
/id <index> is the index of the hub to be programmed.
b) Program SPI flash firmware and erase existing Pseudo-OTP configurations.
>pt2main.exe /pspi < firmware_filename.bin> /id <index> /e
-
/e is the option to erase existing Pseudo-OTP configurations.
For the device specific hub filter approach, append the command "/iv" with all
generic commands as follows
>pt2main.exe /pspi < firmware_filename.bin> /id <index> /iv
