Reply-To: BlueZ development List-Id: BlueZ development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Sender: bluez-devel-bounces@lists.sourceforge.net Errors-To: bluez-devel-bounces@lists.sourceforge.net Hi everyone, I'm trying to backup the firmware from a Conceptronic CBT100U USB Bluetooth dongle using dfutool, and the message I get after selecting the device is: # dfutool -dhci0 archive file.dfu ... "Can't identify device with DFU mode" # I understand this could mean this chip manufacturer does NOT support DFU, although it is a CSR-based device, and mostly all CSR based modules and dongles support DFU. How can I confirm if DFU is supported? Sorry but I couldn't find any info on the net (apart from the dfutool source code). From a quick code overview, it seems usb_find_devices() fails to find the device. The device revision details do not confirm it is a ROM-only device (Thanks Marcel for the suggestion): # hciconfig hci0 revision hci0: Type: USB BD Address: 00:10:60:A6:0C:BC ACL MTU: 192:8 SCO MTU: 64:8 HCI 16.4 Chip version: BlueCore02-External Max key size: 56 bit SCO mapping: HCI Thanks! -- RS ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
