USB port charging logic(power delivery direction?)

[dynameis tw]

I have "VR P10" earbud , it can work on any android device but not XR Elite

it can use with xr elite when you plug the dongle in to charge port on battery pack , but when I plug charger to dongle , it can't charge xr elite I guess it's relate to PD charge direction prefernces,  I pretty sure that is software issue , and if you use glasses mode it just not power on if you plug dongle then plug power on dongle

Can you explain it a little further?

P10 dongle <-> Battery pack <-> VIVE XR headset (Working)
Power <-> P10 dongle <-> Battery Pack <-> VIVE XR headset (Not working?)

can reply now, I'll post info I DM you here for better issue tracking

------------------------------

VIVE XR headset <-> Battery Pack <-> P10 dongle  (earbud working)

VIVE XR headset <-> Battery Pack <-> P10 dongle <= Power(after dongle pluged and earbud connected)  (earbud working but not charging)

Power <-> P10 dongle(connect power to P10 first) => Battery Pack <-> VIVE XR headset  (earbud NOT working , but charging)

 

I don't know if it's dongle problem , but since it work on my google pixel 6 / switch / quest 2 etc, i guess should work on XR Elite too

We kind of figure out where the problem is, but we need more time to check the schedule for it.
