Under the Ports (COM & LPT) section, the device TI CC2540 Low- Power RF to USB CDC Serial Port appears. Next to the name should be the port number (COM#). Note this port number, as it is needed to use BTool. 2.3 Start BTool. Before using this module, CC2540 USB Dongle driver has to be downloaded and installed (signed.zip). After driver installation, in Device-Manager the CC2540 USB dongle is shown. Please note the assigned COM port, which is necessary to configure BTool in next step. If you think you might be experiencing a problem with the TI driver, you might try first testing whether the device can be recognized by other bluetooth-compatible devices. If it turns out the driver is the problem, since it is created by TI, you might also try looking on the TI forums to see if a work-around is already available. The musb device or gadget controller driver binds the controller hardware and specific gadget driver (filestorage, cdc/rndis etc). Linux USB Stack Architecture edit As shown in the figure, linux usb stack is a layered architecture, with musb controller at the lowest layer, the musb host/device controller driver binds the musb controller.

The salient features of the MUSB USB2.0 OTG controller are:
*High/full speed operation as USB peripheral.
*High/full/low speed operation as Host controller.
*Compliant with OTG spec.
*15 Transmit and 15 Receive Endpoints other than the mandatory Control Endpoint 0.
*Double buffering support in FIFO.

*Interfaced with CPPI4.1 DMA controller with 15 Rx and 15 Tx channels (for each usb controller).
*Defer interrupt enable feature is supported for each packet descriptor of cppi-dma.Mentor graphics controller driver (or MUSB driver) [edit]
The MUSB driver is implemented on top of Mentor controller IP which supports all the speeds (High, Full and Low). AM33XX USBOTG subsytem uses CPPI 4.1 DMA for all the transfers. The musb driver conforms to linux usb framework and supports both PIO and DMA mode of operation. The musb host controller driver (HCD) binds the controller hardware to linux usb core stack. The musb device or gadget controller driver binds the controller hardware and specific gadget driver (filestorage, cdc/rndis etc).Linux USB Stack Architecture [edit]
As shown in the figure, linux usb stack is a layered architecture, with musb controller at the lowest layer, the musb host/device controller driver binds the musb controller hardware to linux usb stack framework. The CPPI4.1 DMA controller driver is responsible for transmit/receive of packets over the musb endpoints.
*The Mentor USB driver can be built as module or built-in to kernel
*Support both PIO and DMA mode (The DMA mode not applicable for control endpoint)
*Support two instances musb controller in otg mode (both usb0 and usb1 controller in otg mode. This will allow host or device operation on each port simultaneously.The driver supports the following features for USB Host (AM33XX)[edit]Host Mode FeatureAM33xxHUB class supportYes Human Interface Class (HID)Yes Mass Storage Class (MSC)YesThe driver supports the following features for USB Gadget (AM33XX)[edit]Gadget Mode FeatureAM33xx Mass Storage Class (MSC)Yes USB Networking - RNDISYes USB Networking - CDCYesThe driver supports the following features for Dual host/gadget (AM33xx)[edit]Dual Mode FeatureAM33x USB0 as OTG, USB1 as OTGYesNot verified features of AM33xx[edit]Not verified featuresam33xWifi supportNot verifiedSerial deviceNot verified

*4.2Reading BLE framesStatus
At this point (2017-05-09), the status is:
*it is pretty clear which commands the default sniffer firmware understands
*I wrote a little test program to dump raw BLE frames
*there is no plugin for WireShark yetIntroduction
This page is about the CC2540 bluetooth low-energy sniffer dongle and getting it to work with Linux.A nice end result could be that it becomes possible to sniff directly in WireShark with this dongle.
I have such a ’WeBee’ dongle that can be found for about E15,- on websites like Aliexpress.
It’s supposedly a CC2540 (or compatible) dongle, the USB id is 0451:16b3.
Interesting links:AnalysisUSB descriptor
When plugging this stick into a Linux machine, you can see it uses only one bulk endpoint.
Reading the identification from the stick with the 0xC0 command, results in the following 8-byte response
You can recognise the 2540 type number in there.USB logs from Windows
This USB device does actually work with Windows:
I’ve captured a log of the communication over USB while the BLE is capturing bluetooth traffic from some iBeacon, using USB pcap.
In the logs, I cannot see any firmware blobs being downloaded to the stick.Probably the stick comes with a pre-loaded firmware of itself to do the BLE sniffing.
The USB control transfer request codes seem to match up with the code in https://github.com/christianpanton/ccsniffer/blob/master/ccsniffer.py
*0xC0, GET_IDENT: returns some kind of identifier
*0xC5, SET_POWER
*0xC6, GET_POWER
*0xC9, no idea, this appears in my USB logs but I can’t find it in the python code
*0xD0, START
*0xD1, STOP
*0xD2, SET CHANProtocol
In the windows sniffer software, it seems there are only two things communicated:
*towards the stick: which radio channel to sniff, and some other radio settings
*from the stick: raw sniffed BLE framesConfiguring the radio
This appears to be done using USB control transfers.
The following requests are sent:Request typeRequestValueIndexDataDescription0x400xC504-Set power0xC00xC6000x00Get power0xC00xC6000x04Get power0x400xC900-???0x400xD2000x27Set channel0x400xD2010x00Set channel0x400xD000-Start capture
Request type 0x40 is a vendor-specific device request from host-to-device.Request type 0xC0 is a vendor-specific device request from device-to-host.Reading BLE frames
This appears to be done using USB bulk input transfers.
I can see a lot of similarities between the USB log and the BLE sniffer log.
Each frame starts with a byte indicating the type of frame, following by two bytes indicating the length of the rest of the frame (encoded as little endian).data frames
The bulk USB data starts off with two bytes indicating the length of the rest of the data.
In the example image on the right:
*00: 0 means this is a data frame
*31 00: length of rest of frame encoded in little endian = 49 bytes decimal
*39 04 29 54: part of the time stamp
*2c d6 be .: data frame contentsunknown frames (tick or ’alive’?)
The stick also returns 4-byte frames, alternating between
and
Interpretation:
*01: 1 means this is a frame of type 1
*01 00: length of the rest of the frame encoded in little endian = 1 byte
*40 or C0: unknown data byteCc2540 Usb DongleSoftware
