At a Glance
- Best USB adapter for FORScan: Vgate vLinker FS OBD2 USB Adapter for FORScan, because the manufacturer lists FORScan optimization, HS-CAN and MS-CAN access, and support for ECU programming.
- Best USB adapter for Ford-family vehicles: VGATE vLinker FS USB FORScan OBD2 Adapter, which is specifically listed for Ford, Lincoln, Mazda, and Mercury vehicles and supports automatic CAN-bus switching.
- Best non-USB alternative for enhanced diagnostics: BlueDriver, but it uses Bluetooth rather than USB and therefore is not a direct match for this keyword.
- Best basic handheld alternative: ANCEL AD410, a wired standalone reader with live data, emissions-readiness functions, and a built-in DTC lookup library.
What Matters in OBD2 Scanners & Diagnostics
This guide evaluates the published manufacturer-listed specifications, connection types, stated vehicle coverage, diagnostic functions, and limitations.
USB compatibility receives priority because it is the defining requirement of the primary keyword. The two vLinker FS products are the direct recommendations. The other four products are comparison references only: BlueDriver is Bluetooth, while the ANCEL, MOTOPOWER, and FOXWELL products are described as handheld OBD2 readers without a manufacturer-listed USB computer connection in the published data.
Best Options
Vgate vLinker FS OBD2 USB Adapter for FORScan
Best for: Windows-based FORScan users who need a USB adapter for deeper vehicle-module access.
The manufacturer lists this Vgate adapter as optimized for FORScan and compatible with USB 2.0 and USB 3.0. It uses the ELM327 protocol and is also listed as compatible with AlfaOBD, VCTool, and other ELM327-based applications. The adapter automatically identifies supported CAN buses, including HS-CAN and MS-CAN, although the manufacturer states that module access depends on the vehicle network architecture.
The product is listed for 12V and 24V vehicles with a standard OBD2 port. The manufacturer describes typical coverage as gasoline vehicles from 1996 onward and diesel vehicles from 2004 onward, while noting that compatibility can vary by year, region, and configuration. Select CAN flow-controlled electric vehicles are also listed, but this should be verified for the specific vehicle before purchase.
Important limitations: Diagnostic software is not included, and the chosen app must support both the vehicle and the adapter. The product is not a self-contained screen-based scanner, so it is a poor choice if you want to plug in and diagnose without a computer or compatible application.
Price listed: $37.99.
VGATE vLinker FS USB FORScan OBD2 Adapter
Best for: Owners of Ford, Lincoln, Mazda, and Mercury vehicles who want USB access to FORScan functions.
The manufacturer describes this adapter as specialized for Ford, Lincoln, Mazda, and Mercury vehicles and designed to work with FORScan. Listed features include access to advanced and hidden functions, vehicle modules, automatic switching between HS-CAN and MS-CAN networks, and support for FEPS 18V programming voltage in FORScan.
The manufacturer also lists a USB 2.0/3.0 connection, up to 3 Mbps transmission, an 8192-byte serial buffer, and support for long-frame communication. These specifications are relevant to users working with FORScan’s advanced functions, ECU programming, or module configuration rather than simply reading a check-engine code.
Important limitations: the listing does not state that software is included, so plan to install compatible software separately. The specialized Ford-family focus makes this less suitable for someone who wants a general-purpose USB adapter for many unrelated makes. Programming and configuration functions also require careful vehicle-specific verification before use.
Price listed: $37.99.
Products That Do Not Match a USB-Focused Purchase
The following products may suit other diagnostic needs, but they are not direct recommendations for a USB OBD2 scanner search based on the listed connection information.
- BlueDriver OBD2 Scanner Bluetooth: The manufacturer lists Bluetooth phone and tablet connectivity, enhanced diagnostics for Check Engine, ABS, SRS, TPMS, and transmission systems, live data, freeze frames, smog readiness, Mode 6 data, and technician-verified repair reports. It is not a USB adapter. Price listed: $94.95.
- ANCEL AD410: This is a wired handheld OBD2 scanner with a built-in display and DTC lookup library. The manufacturer lists code reading and clearing, live data, freeze frame, I/M readiness, O2 sensor and EVAP tests, vehicle information, and MIL status. A USB computer connection is not listed. Price listed: $39.99.
- MOTOPOWER MP69033: This handheld reader draws power from the vehicle’s OBD2 connector and includes a 2.8-inch LCD, nine-protocol support, live data, freeze frame, I/M readiness, and a DTC lookup library. It does not support ABS or airbag codes, and a USB connection is not listed. Price listed: $15.97.
- FOXWELL NT301: This wired code reader is listed for reading and clearing engine fault codes, emissions readiness, live data graphing, VIN retrieval, and MIL reset on compatible vehicles. A USB computer connection is not listed. Price listed: $55.96.
Fitment and Compatibility Notes
Check the vehicle before buying
A standard OBD2 port does not guarantee access to every module or function. The Vgate listings describe typical gasoline coverage from 1996 onward and diesel coverage from 2004 onward, but they also state that compatibility depends on year, region, vehicle configuration, and network architecture. Confirm the exact make, model, year, engine, and intended software before ordering.
USB adapter versus handheld scanner
A USB adapter transfers diagnostic data to a computer or another compatible host. That can be useful for FORScan, AlfaOBD, VCTool, ECU programming, and module-level work, but it requires separate software and a suitable computer or device.
Do not confuse USB with Bluetooth
BlueDriver connects wirelessly to a phone or tablet through Bluetooth. Its stated functions may appeal to drivers seeking enhanced diagnostics, but it does not satisfy a requirement for a physical USB connection. If a laptop-based workflow is essential, choose one of the vLinker FS products instead.
Selection Guide
- Choose the software first. FORScan users should verify that the adapter and vehicle are supported. The Vgate listings specifically mention FORScan, while the first vLinker listing also mentions AlfaOBD, VCTool, and other ELM327 applications.
- Confirm the connector and host device. Both direct recommendations use USB and are listed as compatible with USB 2.0 and USB 3.0. Make sure your computer has a suitable USB port and that the software can communicate with the adapter.
- Match the vehicle network. HS-CAN and MS-CAN access is listed for the vLinker FS products, but the manufacturer states that available module access depends on the vehicle’s architecture.
- Separate code reading from programming. Reading and clearing codes is different from ECU programming or configuration. The vLinker FS listings mention programming-related support, but the required software, vehicle conditions, and procedure must be confirmed before attempting advanced work.
- Consider whether you need a screen. If you want a standalone reader for basic engine diagnostics, the ANCEL AD410, MOTOPOWER MP69033, or FOXWELL NT301 may be more convenient than a computer adapter. They are not, however, direct USB picks from the published data.

Common Questions
What is the best USB OBD2 scanner in this comparison?
The Vgate vLinker FS OBD2 USB Adapter is the strongest general USB recommendation for FORScan because the manufacturer explicitly lists USB connectivity, FORScan optimization, ELM327 compatibility, and HS-CAN/MS-CAN access. Vehicle and software compatibility still need to be confirmed.
Are the two vLinker FS products the same?
They share the vLinker FS name and a $37.99 listed price, but the published descriptions emphasize different strengths. The Vgate listing highlights FORScan stability, ELM327 applications, and broad 12V/24V vehicle coverage. The VGATE listing emphasizes Ford, Lincoln, Mazda, and Mercury vehicles, automatic CAN switching, transmission speed, long-frame communication, and FEPS 18V programming support.
Does a USB OBD2 adapter include diagnostic software?
The Vgate vLinker FS listing explicitly states that diagnostic software is not included. The published information for the second vLinker product does not state that software is included, so verify the package contents before buying.
Can BlueDriver be used as a USB OBD2 scanner?
Not according to the published product information. BlueDriver is listed as a Bluetooth scanner that connects to a phone or tablet, so it is not a direct match for a USB-only requirement.
Can these products read ABS or airbag codes?
BlueDriver is listed with ABS and SRS/airbag coverage. MOTOPOWER specifically states that ABS and airbag codes are not supported. The published descriptions for the vLinker FS adapters, ANCEL AD410, and FOXWELL NT301 do not establish ABS or airbag coverage, so do not assume those functions are available.
The Bottom Line
For a genuine USB connection, the two vLinker FS adapters are the only direct matches in this six-product comparison. Choose the Vgate version for a broader ELM327 and FORScan-oriented description, or choose the VGATE version when Ford-family vehicles and advanced FORScan functions are the priority. If you do not need USB, the listed handheld readers offer a more self-contained format, while BlueDriver offers Bluetooth-based enhanced diagnostics. Before purchase, verify the exact vehicle, software, network access, and diagnostic function you need.
