Hi Teradici,<br />
<br />
The vendor ID is seen in the USB traces corresponding to the USB transactions that occur upon device attachment aka device enumeration.<br />
<br />
This can be easlily seen by using any USB Protocol analyzer with the Plantronics headset, in the device descriptor - I have pasted it below for the C5210 device:<br />
<div>bLength<span style="white-space:pre"> </span>18</div>
<div>bDescriptorType<span style="white-space:pre"> </span>DEVICE (0x01)</div>
<div>bcdUSB<span style="white-space:pre"> </span>2.00 (0x0200)</div>
<div>bDeviceClass<span style="white-space:pre"> </span>Defined in Interface (0x00)</div>
<div>bDeviceSubClass<span style="white-space:pre"> </span>Defined in Interface (0x00)</div>
<div>bDeviceProtocol<span style="white-space:pre"> </span>Defined in Interface (0x00)</div>
<div>bMaxPacketSize0<span style="white-space:pre"> </span>64</div>
<div><strong>idVendor<span style="white-space:pre"> </span>0x047f</strong></div>
<div>idProduct<span style="white-space:pre"> </span>0xc054</div>
<br />
Hope that answers your Q<br />
