btmon trace
Hello,
I own a bluetooth USB adapter that fails to initialize.
The other bugs I saw deal with other device, hence this new one.
$ sudo hciconfig
hci0: Type: Primary Bus: USB
BD Address: 00:1A:7D:DA:XX:XX ACL MTU: 679:9 SCO MTU: 48:16
DOWN
RX bytes:1722 acl:0 sco:0 events:90 errors:0
TX bytes:1104 acl:0 sco:0 commands:90 errors:0
$ sudo hciconfig hci0 up
Can't init device hci0: Operation not supported (95)
The device is the following one (full lsusb output attached as file)
Bus 001 Device 008: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle
(HCI mode)
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 1.10
bDeviceClass 224 Wireless
bDeviceSubClass 1 Radio Frequency
bDeviceProtocol 1 Bluetooth
bMaxPacketSize0 64
idVendor 0x0a12 Cambridge Silicon Radio, Ltd
idProduct 0x0001 Bluetooth Dongle (HCI mode)
bcdDevice 88.91
iManufacturer 0
iProduct 2
iSerial 0
I attach a btmon trace that seems to indicate that the "Delete Stored Link Key"
is not supported.
Is there a way to support this device in degraded mode in case the feature is
not supported ?
Cheers
