i'm pretty sure i have the P version, and i did flash latest firmware for P version, i did a complete Z2M setup as i also swapped my raspberry for a mini pc at the same time but i haven't tried with an usb extender, will try that in a few hours and will update my comment. Is there a way to check visually if i have the P version ? Thanks for your answer
Edit: can confirm i have P version, model: ZBDongle-P Edit2: just tried to pair them again with an usb extender but still same
