"Failed with Failed to detect reset response"

[SkaveRat]

I'm running Arch linux, and currently trying to sync my (classic) fitbit, but this is the output I get

Anybody got an idea what is wrong?

Found FitBit base
Start reset () {}
    sent: ['xx', 'xx', 'xx', 'xx', 'xx']

[a pause here...]

Fail reset
Failed with Failed to detect reset response
