I had computer freezes with BTConfig running using several different versions back during the earlier days of the P25RX.
I learned that plugging my P25RX into any USB port that connected to one of the motherboards ASMEDIA USB controllers was the culprit.
I can still create the same freeze or lockup today with the latest BTConfig version after they run random amounts of time and are plugged into an ASMedia port.
As long as I use any of the Intel based USB chipsets built on the same motherboard, BTConfig will run for days without ever freezing. I'm with
@btt on this one with his thinking it's probably a hardware issue.
I've also had some luck in the past by using a tiny non powered or powered USB 2.0 hub plugged into the ASMedia 3.1 ports.
The use of the 2.0 speed hub seemed to greatly reduce the frequency of freezing I'd see not just with BTConfig but with RTL-SDR tuners and their software also. I never did figure out the root cause of the freezing problem when some devices were plugged into USB 3.0 or 3.1 ports but putting them on slower speed hubs often helped.
If you have different chipset USB ports on your computer and still see freezes with BTConfig, try plugging you P25RX into one of the other USB ports and see if that helps.
