I am using indeed 7.6R1.9 . I wasn't aware of this bug. Thanks!
By redoing it again, I managed to activate the trunk by forcing "channel-group 1 mode on" on both 3750 interfaces, putting the M320 in LACP passive mode and forcing all ports in a "no negociation" mode (they were already in this state before).
As far as I have understood, in this mode, LACP is not activated on Cisco side.
CBV1SC(config-if)#channel-group 1 mode ?
active Enable LACP unconditionally
auto Enable PAgP only if a PAgP device is detected
desirable Enable PAgP unconditionally
on Enable Etherchannel only <---- HERE
passive Enable LACP only if a LACP device is detected
What does LACP bring more when it is working compared to this "Etherchannel only" mode ? Is it less reliable to leave it in this state without LACP activated ?
For Vijay, I think that in my case , the M320 and the 3750 are negotiating themselves which actor and partner key.

What version are you running ? If you are on 7.6-8.1 then you are
effected with PR95015. LACP did not used always the correct
interface index .32767 once you have received it. If you
deactivate/activate the ge-4/1/4 and ge-4/1/5 then you should
get the aggregate into up state.
thanks
