Tool/software:
We are using the TPS65982 in a design with two short USB-C extension cables and a standard USB-C cable between them going out to a USB-C display that uses the USB2.0 lines for touchscreen data. Due to to use of the extension cables, there are cable configurations where the CC1 and CC2 lines do not indicate the correct orientation of the cable for the USB2.0 D+/- lines. A solution to this challenge is to jumper the C_USB_TP and C_USB_BP lines together and jumper the C_USB_TN and C_USB_BN lines together at the USB-C connector of our board that contains the TPS65982. In this configuration, the USB2.0 data is available at the upstream USB_RP lines regardless of the TPS65982 port multiplexer state, since the data is on both sets of lines from the USB-C connector. Are there any drawbacks to jumpering the lines this way? The other solution would be to keep the jumpering on the USB-C connector as described and bypass the TPS65982 port multiplexer and connect the D+/D- from the USB-C connector directly to the upstream D+/D- lines.
