TUSB4020BI: D+/D- swapped

Part Number: TUSB4020BI

Is it possible on the TUSB4020BI to have the device swap the D+/D- on the USB inputs? There is a note in the datasheet stating "DM/DP Polarity Swap" was deleted. This implies there was the ability to swap the pins at some point. Of course I'm asking because I routed these incorrectly on my board and wanted to find out if there was a workaround.

  • Hi David,

    No, the TUSB4020B doesn't support polarity swap, that is why it was removed from the datasheet.  That feature exists in our 4 port hub and it got added to the 2-port datasheet in error.

    Sorry, there isn't a hub configuration workaround available.

    Regards,
