issue with two muse2 devices recording simultaneously

[KaivinC]

I wrote a program base on the record.py in the example and tried to use two muse2 devices to record data simultaneously. when the program starts, everything is fine, two muse streams can be detected, and the recording is working, but the only problem is the timestamp of data pull from one device is slower obviously than the other one. I'm not sure where I'm going wrong. Is there any example of multiple device records? Thanks!

p.s. Using windows 11 and BlueMuse
