CONFIG_BT_SMP_USB_HCI_CTLR_WORKAROUND

Workaround for USB HCI controller out-of-order events

Workaround for USB HCI controller out-of-order events

Type: bool

Help

This option enables support for USB HCI controllers that sometimes
send out-of-order HCI events and ACL Data due to using different USB
endpoints.
Enabling this option will make the central role not require the
encryption-change event to be received before accepting key-distribution
data.
It opens up for a potential vulnerability as the central cannot detect
if the keys are distributed over an encrypted link.
