Hi Gareth,

Yes, this should be okay, so long as D- and D+ are coming in and out of the same related port (I.E D- going into 1/2D+, D- coming out of D+.) Just ensure that the lane polarities are correctly connected to the device and host as well.

Please let me know if you have any other questions.

Thanks,

Ryan
