I ran Wireshark USBPCap1 and found somethings going on, on my laptop so I have several questions to ask. I have 1,2,3,4 device addresses. How can I tell where the device is located and who is accessing these USBD_STATUS_SUCCESS (0X00000000) URB Function: URB_FUNCTION_GET_DESCRIPTOR_FROM_DEVICE (0X00b).Then a Response that includes a URB_FUNCTION_CONTROL_TRANSER, that is a success with a Hi-speed hub with single TT and Integrated Rate Matching Hub. Why did this take place?
I have another one that has a response that this device supports REMOTE WAKEUP. How do I find out more about this device and why this configuration and the request happened?
Then there is a Device Descriptor that show DEVICE DESCRIPTOR bLength: 18 bDescriptorType: 0x01 (DEVICE) bcdUSB: 0x0200 bDeviceClass: Miscellaneous (0xef) bDeviceSubClass: 2 bDeviceProtocol: 1 (Interface Association Descriptor) bMaxPacketSize0: 64 idVendor: Microdia (0x0c45) idProduct: Sonix 1.3 MP Laptop Integrated Webcam (0x6480) bcdDevice: 0x9a07 iManufacturer: 2 iProduct: 1 iSerialNumber: 0 bNumConfigurations: 1
My laptop computer's webcam is disabled, and the aforementioned does not match the drivers of my webcam in the Device manager. I looked for anything that would match and I found nothing in Device Manager.

There is a Frame or Packet where the device is not self powered but it is remote wake up. Since, I have left my computer unattended for a 15 min. then I just thought I would add this. I thought this was the frame that said it was remote wake up but it shows that it is not. There are only 333 Frames.
My network status at the time was Online via ethernet.
Thank you in Advance,
