Maybe flow control for SCO must be explicitly switched on on broadcom? It seems that one can switch on and off flow control for SCO (but switched off completion events should not be sent at all). There is another thing with flow-control in in bluez: as far as I see the code assumes to get a completion event for every packet submitted to the controller. But this is not necessarily the case. A HCI_EV_DISCONN_COMPLETE for a connection implicitly completes all packets of that connection. I don't know if any controller uses this feature, though. > > Please also include the lspci for these devices. > Regards, -- Wolfgang Walter Studentenwerk M?nchen Anstalt des ?ffentlichen Rechts Leiter EDV Leopoldstra?e 15 80802 M?nchen Tel: +49 89 38196 276 Fax: +49 89 38196 144 wolfgang.walter@studentenwerk.mhn.de http://www.studentenwerk.mhn.de/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
