Polar v650

[ArsenyMironov]

Hi!

I'm trying to use your software with Polar v650. The list command does see the device, but when I try to connect it I get an error

loophole(no device)>list
0 - Polar V650 (BUEY4HDMAIMVW8OJ)

loophole(no device)>connect 0
Traceback (most recent call last):

Is it possible to solve?

Thanks!

It is hard to tell based on this stack trace. It seems like USB access issue.

I'm getting the same, here's a strace:

I'm not sure if this will look familiar to you.
