I have bought a OSDK expansion module for matrice 300 but the adapter does not feel right. After plugging into the osdk port, I measure voltage of power port and it is around 0.2V. And if I connect the computer and adapter board's usb port, the computer can detect nothing. I do not know if the adapter board malfunctions. Any advice?

I don't know if I actually solve the issue but it is interesting for those who may encounter the same issue. I opened the case of module and tried to diagnose where the issue is with a multimeter. After half a day of diagnosis and countless number of rebooting the drone, I could not see any obvious error on the module. I gave up and restore the module, and then gave a last try of reboot. Then everything becomes normal. 24V is back. The computer can detect the usb.
Wow! Thank God!
I think it is probably due to the bad contact at the OSDK port or the usbc port inside the module. I am not advising anyone to re-plug the usbc port inside as it may void the warranty but it was what I did before the module was workable.
Good Luck!
