This hasn’t really been addressed at all by anyone at Pimax. But from what we have seen with there being only one usb port on the 8kx and there not being any passthrough possibilities on the eye tracking and hand tracking modules we will be forced to choose one or the other and not be able to use both at the same time. For me this is a huge issue as I was planning on using both modules and imo this lowers their value considerably and makes me second guess even purchasing them.
It’s still easy just run a usb cable directly from the passthrough on the eye tracking module itself to your pc, it does have one. It’s only the HT that does not.
Q&A question #1 does answer the technical reason for the top port removal.
