[bluetooth-dev] csr_change_if Invalid argument



Hi

For H4 the openbt stack works fine. But after changing the modus to BCSP
we get the following error message after running btdm:

Registered bluetooth line discipline on /dev/ttyS0
Please reset HW board within 5 seconds
csr_change_if: Invalid argument
Shutting down Bluetooth stack

/var/log/messages:

Has anyone an idea what could be wrong?
