Figure 376 USB Detected Devices
The Vendor, Product and ID details are obtained by querying the devices directly. The ID field is a
combination of the Product ID, Vendor ID, and Serial Number. If this is missing, or the same as any
other devices, then configuring and using the device may be unreliable.
The Driver field shows the driver module loaded to utilize the USB device. If this is listed as (None), then
the appropriate sub-system may not be currently enabled or the driver may need to be manually loaded.
Refer to the Technical Support Knowledge Base for a list of what devices are supported, and how to
manually load drivers for devices that are not automatically detected.
Packet Capture page
You can capture network traffic in a packet capture (pcap) file. Packet captures are saved to n.pcap files in
the /var/tmp directory. You can either download or decode the .pcap file. This can be useful for diagnosing
network problems. The downloaded file can also be viewed using freely available utilities such as tcpdump
or Wireshark.
