I use self made hub pcba. So seems in terms of software it is ok, just schematics need to be updated.

Sorry, we do not consider hubs that require -f as compatible. Also, it you made this hub yourself, that is not something average person can buy.

@nikitos1550 Thanks for sharing the info. I was looking for a chip to build a hub that support this feature. I saw CH335 which claim supporting individual port control but the FAE has not confirmed if the power can be controller by software.

Would you mind sharing the output of sudo lsusb -v?
