Hi guys, I hope this can be the right place where to find help for my problems. I need to use the dongle Asus USB-BT400 to provide Bluetooth support for my Raspberry Pi in which I installed the Raspbian distribution. I have to work with Raspberry Pi and a BLE device called SensorTag from Texas Instruments. So I have to use the gatttool command from Bluez. I followed the instructions from this site to set up Bluez in my Raspberry Pi with Raspbian. http://mike.saunby.net/2013/04/raspberry-pi-and-ti-cc2541-sensortag.html I downloaded and installed the last version of Bluez 5.11. I plugged in my BLE USB dongle in my Raspberry Pi but I think there are some problems. When I type in the command "hciconfig" I have no output results. And also when I type in "hcitool dev" no devices is listed. But when I type in "lsusb" the output is: Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. Bus 001 Device 004: ID 0b05:17cb ASUSTek Computer, Inc. The last one is my USB dongle, so I think the hardware is correctly recognized. Which could be my problem? I also tried the dongle Asus USB-BT400 in my notebook with Xubuntu 13.10 and it worked very well (hciconfig sees the bluetooth interface). I also read something about my dongle by googling and I found the message linked below from this mailing list, so I thought you can help me or give me a way forward. http://marc.info/?l=linux-bluetooth&m=137812308709357&w=2 Maybe I can edit some source files to add the device ID? If yes, which changes I have to do?
