I've been trying to get the bluetooth working on the T100TAF.

i've added the device ACPI BCM2E65 to hci_bcm.c
the bcm_uart_subver_table is already there for the device 0x410e,"BCM43341B0"

[pinkflozd@Bazdara-T100TAF ~]$ sudo btattach --bredr /dev/ttyS4 -P bcm

[pinkflozd@Bazdara-T100TAF ~]$ hcitool scan

    F8:E0:79:B3:C3:A7    Moto G

hcitool cc F8:E0:79:B3:C3:A7 

shows no error but doesnt connect to devices, its also not visible to other
devices

How can i further debug it?

Should i also add this device to btbcm_initialize() and btbcm_check_bdaddr()?
