StarTech USB2CB1M USB-C to USB-B Peripheral Cable

Overview

The StarTech USB2CB1M is a 3.3 ft (1 m) USB 2.0 cable that bridges USB-C host ports to USB Type-B devices — the square-connector standard found on most laser printers, label printers, document scanners, and similar peripherals. If your workstation or thin client has moved entirely to USB-C but your floor-level devices still run USB-B, this cable closes that gap without adapters stacked on adapters. At just 27 g, it adds no meaningful weight or bulk to any install.

Key Features

• 480 Mbps USB 2.0 throughput: Matches the native speed ceiling of virtually every USB-B printer and scanner on the market — you won't bottleneck a label printer or document feeder that was never designed to exceed USB 2.0 rates anyway. No speed is left on the table for these device classes.
• 3.3 ft (1 m) cable length: Sized for a direct workstation-to-device run on a desk or in a rack-adjacent equipment bay. Long enough to reach a floor-standing printer from a nearby workstation without slack piling up; short enough to keep cable management clean.
• USB-C host connector: Fits any USB-C port delivering USB 2.0 or higher data — laptops, desktop front panels, docking stations, thin clients, and single-board compute nodes. No driver installation required on any major OS.
• USB Type-B device connector: The full-size square USB-B plug is the universal standard for printers, flatbed scanners, label applicators, and bench-top test instruments. One cable covers the majority of legacy-port peripherals you're likely to encounter.
• Compact form factor (0.5 in W × 0.4 in H): The connector profile is narrow enough to sit alongside other cables in a tight USB-C port cluster without blocking adjacent ports — a real consideration on compact laptops and mini PCs where port spacing is minimal.
• Lifetime warranty: StarTech backs the USB2CB1M with a lifetime warranty, which means you're not treating this as a consumable. For managed deployments where swapping a cable means a service call, that coverage matters.

Integration and Compatibility

The USB2CB1M works with any host that exposes a USB-C port operating in USB 2.0 mode or higher — including Thunderbolt 3/4 ports, which are backward-compatible with USB 2.0 data. On the device side, it seats into any full-size USB Type-B port. Common pairings include network-connected label printers used in tandem with barcode scanners on warehouse lines, document scanners integrated into networked workstation environments, and USB-attached peripherals in surveillance system build-outs where configuration laptops connect to USB-B-equipped encoders or DVRs. The passive design means no firmware, no power draw from the host beyond what the connected device requests, and no compatibility exceptions across Windows, macOS, Linux, and ChromeOS.

Frequently Asked Questions

Q: What is the data transfer rate of the USB2CB1M?

A: The USB2CB1M supports USB 2.0 speeds up to 480 Mbps — sufficient for printers, scanners, and most USB-B peripherals that were designed around USB 2.0 from the start.

Q: What devices is the USB2CB1M compatible with?

A: Any device with a full-size USB Type-B port, including laser and label printers, flatbed scanners, and bench instruments. The host end requires a USB-C port (USB 2.0 or higher, including Thunderbolt 3/4).

Q: What warranty does the USB2CB1M carry?

A: StarTech provides a lifetime warranty on the USB2CB1M.

Q: Will the USB2CB1M work with a Thunderbolt 3 or Thunderbolt 4 port?

A: Yes. Thunderbolt 3 and 4 ports are backward-compatible with USB 2.0, so the USB2CB1M will function correctly in those ports for data transfer to USB-B devices.

Q: Does the USB2CB1M support video or charging?

A: No. This is a USB 2.0 data cable only. It does not carry video signals and does not support USB Power Delivery charging. It is designed solely for data connectivity between a USB-C host and a USB-B peripheral.

Marty Allison

The USB2CB1M comes up regularly in deployments where someone has refreshed their workstation fleet to USB-C-only machines but the attached label printers, document scanners, or configuration terminals are still running USB-B connectors. At 480 Mbps over a 1 m run, there is no practical speed gap for these device classes — a thermal label printer or a flatbed scanner will never saturate USB 2.0 bandwidth, so you're not leaving anything behind by staying on this standard.

Technical Highlights:

• 480 Mbps USB 2.0: Matches the native throughput ceiling of USB-B printers and scanners — no adapter-induced bottleneck, and no USB 3.x overhead wasted on devices that can't use it.
• 1 m cable length: Keeps runs tight and cable management clean in desk or rack-adjacent setups; avoids the slack management problem that comes with over-length cables in organized wiring environments.
• Lifetime warranty: In a managed environment where a cable swap requires a dispatch, lifetime coverage means this is a one-time procurement decision rather than a recurring replacement line item.

Deployment Considerations:

• The 1 m length is purpose-built for direct workstation-to-peripheral runs. If the USB-B device sits more than roughly 3 feet from the host port, plan for a longer variant rather than introducing a coupler — couplers add a failure point and can drop signal integrity on marginal USB 2.0 circuits.
• This cable carries data only — it will not charge a device or pass video. Connecting it to a USB-C port that is Thunderbolt-only with no USB fallback (rare but possible on some embedded systems) will yield no connection; verify the host port supports USB 2.0 data mode before deploying at scale.

The USB2CB1M is the right call for warehouse automation stations pairing a USB-C thin client with a USB-B label printer, or for IT deployment kits where a technician needs to connect a USB-B-equipped DVR or encoder to a modern laptop for initial configuration — clean, simple, and warrantied for the life of the install.
