Exam: USB Device Identification — "VID 0951 PID 1666" and Related Concepts

Duration: 60 minutes
Total points: 100

Instructions: Answer all questions. Show calculations or commands where requested. Practical tasks may require running commands or inspecting sample outputs; if you cannot execute them, explain expected results and how you would validate them.

Section A — Short answers (5 × 6 = 30 points)

1. (6 pts) Define the terms USB VID and PID. Explain their roles in device identification and driver binding.
2. (6 pts) What organization assigns USB Vendor IDs (VIDs)? How can smaller developers obtain unique device IDs if they cannot register a VID?
3. (6 pts) Given “VID=0951 PID=1666”, identify the vendor and describe at least two likely device types associated with that vendor based on the VID alone.
4. (6 pts) Explain what USB device classes are and why they matter when the same VID/PID appears across multiple product models.
5. (6 pts) Describe what a USB device descriptor is and list the key fields you would inspect to troubleshoot a device that is not recognized by the OS.

Section B — Practical identification and commands (4 × 12 = 48 points) 6. (12 pts) On Linux, provide the exact commands to locate a USB device with VID 0951 and PID 1666, show its kernel device path, and display its full descriptor. Explain briefly what each command outputs.

• Expected commands: use lsusb, grep/filtering, and a method to dump descriptors (e.g., lsusb -v or usbdevfs).

7. (12 pts) On Windows, describe step-by-step how to find a device by VID/PID using built-in tools (Device Manager, Details tab) and provide a PowerShell one-liner that lists connected USB devices with their VID/PID.
8. (12 pts) On macOS, provide the Terminal commands to list USB devices and filter for VID 0951 PID 1666, and explain which system report fields confirm the device identity.
9. (12 pts) Suppose you plug in the device and the OS loads the wrong driver. Detail the steps to override driver selection on (a) Linux (udev rule and driver unbind/bind), (b) Windows (inf modification/driver installation), and (c) macOS (kext management or driver blacklist). For each, include risks and a safe rollback method.

Section C — Troubleshooting scenario (20 points) 10. You receive a support ticket: “Customer connected a USB device identified as VID=0951 PID=1666; Windows shows ‘Unknown USB device (Device Descriptor Request Failed)’.” Provide a structured troubleshooting plan (10 steps maximum) to isolate and resolve the issue. Include at least three distinct diagnostics (software and hardware) and two practical remediation actions. State expected outcomes for each diagnostic.

Section D — Educational extension (2 × 6 = 12 points) 11. (6 pts) Explain how USB device spoofing (changing reported VID/PID) can be used legitimately and maliciously. Provide two practical tips for defenders to detect spoofed devices on a network or host. 12. (6 pts) For an embedded developer building a USB product derived from a mass-storage controller that shows VID 0951 PID 1666 by default, explain how to ensure unique identification for production units (bootloader/fuse approach, serial numbers, and recommended USB descriptor fields to set). Provide one concise sample of a device descriptor fragment illustrating vendor, product, and serial string values (present as plain text, not binary).

Practical tips (bonus — up to 10 bonus points, awarded at grader's discretion)

• Include at least five concise, practical tips for working with VID/PID investigation, driver issues, and safe device testing. Each tip = up to 2 points.

Grading rubric notes (for graders)

• Accuracy of commands and expected outputs.
• Clarity and completeness of troubleshooting steps.
• Demonstrated understanding of USB descriptors and driver binding.
• Practical security awareness regarding spoofing and safe handling.

Answer key highlights (concise)

• VID: vendor ID; PID: product ID; assigned by USB-IF; alternatives include PID sharing using vendor’s chips, or using software-based unique IDs like USB serial numbers.
• VID 0951 corresponds to Kingston Technology (commonly flash storage, card readers, secure USB devices). PID 1666 likely maps to a specific Kingston product — check lsusb/Windows Device Manager for exact model.
• Linux commands: lsusb | grep -i "0951:1666"; lsusb -d 0951:1666 -v; dmesg | tail for kernel messages; read /sys/bus/usb/devices/*/uevent for device path. Explanation: lsusb lists bus:device and ids; -v shows descriptors; sysfs exposes power, driver binding info.
• Windows: Device Manager → View → Devices by connection → find device → Properties → Details → Hardware Ids; PowerShell example: Get-PnpDevice -PresentOnly | Where-Object Get-PnpDeviceProperty -KeyName 'DEVPKEY_Device_HardwareIds').Data -match 'VID_0951' (or use Get-WmiObject Win32_PnPEntity and parse DeviceID). Explain driver reinstall via pnputil or INF.
• macOS: system_profiler SPUSBDataType | grep -A 10 "0951" or ioreg -p IOUSB -l; confirm Product ID/ Vendor ID and Serial Number.
• Driver override: Linux — write udev rule matching idVendor/idProduct, use driver_override or echo to unbind/bind; Windows — create signed INF or use test-signing and pnputil to install; macOS — avoid unsigned kexts on modern macOS, use DriverKit or proper signed kext; rollback: remove rule/driver, reboot, restore from backup.
• Troubleshooting plan: check cables/ports, test on another host, check dmesg/Event Viewer, test with powered hub, try alternate drivers, check power draw (usbtop/USB Power Monitor), update firmware, reinstall driver, replace device if HW fail.
• Spoofing detection tips: verify serial numbers, check device class vs expected function, monitor unexpected USB mass-storage mounts, use USB filtering and allow-listing, check firmware hashes where possible.
• Descriptor fragment example: idVendor: 0x0951 idProduct: 0x1666 iManufacturer: "Kingston" iProduct: "DataTraveler 1666 Prototype" iSerial: "SN20260324A01"

Understanding USB Device ID: VID 0951 & PID 1666 The hardware identifiers VID 0951 and PID 1666 correspond to the Kingston DataTraveler 100 G3 or Exodia series USB 3.0 flash drives.

When you see these IDs, your computer is identifying the specific manufacturer and product model to load the correct drivers. 🛠️ What Do These IDs Mean? Every USB device has unique identification codes: VID (Vendor ID) 0951: Registered to Kingston Technology.

PID (Product ID) 1666: Refers to the DataTraveler 100 G3 / Exodia hardware line.

Link: This usually refers to the connection interface (USB 3.0/3.1) or the search for firmware/drivers. 🚀 Common Uses and Drivers

Most modern operating systems handle these devices automatically.

Windows 10/11: Uses "Plug and Play" (PnP) drivers. No manual install needed.

Linux: Recognized by the kernel as a standard mass storage device. macOS: Mounts automatically as a generic external drive. When You Need a Manual Link If the device is not showing up, you might be looking for:

Firmware Updates: Kingston occasionally releases firmware to fix "Write Protect" errors.

Formatting Tools: Kingston’s "Format Utility" is better than Windows' default tool for these specific chips.

Data Recovery: Specific software often asks for the PID/VID to identify the controller chip (like Phison or Skymedi). ⚠️ Troubleshooting "Device Not Recognized"

If your computer sees the ID but can't access the files, try these steps: 1. Update Drivers via Device Manager Right-click Start > Device Manager. Expand Universal Serial Bus controllers. Find the entry for Kingston/Mass Storage Device. Right-click > Update driver. 2. Check Disk Management Search for "Create and format hard disk partitions." Look for a "Removable" disk with "Unallocated" space. Right-click the block and select New Simple Volume. 3. Fix Write Protection

If the drive is "Read Only," the PID 1666 hardware may have locked itself to prevent data loss.
