StarTech USB2CB2M USB-C to USB-B Cable — 6.6 ft, 480 Mbps

Overview

The StarTech USB2CB2M is a 6.6 ft (2 m) USB 2.0 cable that bridges USB Type-C and Thunderbolt 3 hosts to USB Type-B peripherals — printers, scanners, label applicators, industrial instruments, and legacy surveillance devices that still ship with a square USB-B port. If your workstation or laptop moved to USB-C and your peripheral hasn't, this cable closes that gap without an adapter in the chain. It carries USB 2.0 Hi-Speed data at up to 480 Mbit/s, which is the native ceiling of the USB-B peripheral side regardless of what your host port supports.

Key Features

• 480 Mbit/s Hi-Speed USB 2.0: Matches the rated throughput of virtually every USB-B device in the field — printers, barcode scanners, USB-connected DVRs, and similar peripherals max out at USB 2.0 speeds, so there is no bottleneck introduced by this cable. You are not paying for USB 3.x bandwidth you cannot use.
• 6.6 ft (2 m) reach: Long enough to route from a desk-mounted peripheral to a workstation tower or under-desk laptop dock without pulling taut. For tighter setups — under 3 ft — consider a shorter variant; for rack or server-room distances you will need an active extension. This length fits most standard USB cable deployment scenarios at a workstation.
• USB Type-C host connector: Compatible with USB-C ports and Thunderbolt 3/4 ports (data only — Thunderbolt alt-mode video and power delivery are not applicable here). Works on any USB-C port that supports USB 2.0 data, which is all of them.
• USB Type-B device connector: The square, beveled connector found on most printers, industrial instruments, bench-top scanners, and rack-mounted serial converters. If your peripheral has a USB-B port, this cable connects it directly to a modern USB-C host — no dongle, no hub required.
• 22/30 AWG wire gauge: 22 AWG on the power conductors supports reliable bus power delivery to USB-B peripherals that draw from the host port. 30 AWG on the data conductors keeps the cable flexible and manageable at desk level. Thicker power conductors matter for peripherals like label printers that spin motors or heat printheads on USB bus power.
• Lifetime warranty: StarTech backs the USB2CB2M with a lifetime warranty — meaning a defective cable is a replacement, not a recurring cost. For deployments where the cable is in a fixed install and hard to access (behind furniture, through cable management), that coverage matters.
• 2.1 oz (60 g) weight: Light enough that the cable does not stress the USB-C port on a laptop or compact host device when routed at an angle. Port stress is a real failure mode on thin-chassis machines; a heavy, stiff cable acting as a lever arm accelerates connector wear.

Integration & Compatibility

The USB2CB2M works with any host featuring a USB-C or Thunderbolt 3/4 port running macOS, Windows, Linux, or Chrome OS — no driver installation required, as USB 2.0 is natively supported by all current operating systems. On the device side, it connects to any USB Type-B peripheral: laser and inkjet printers, label printers, flatbed and document scanners, USB-B hubs, Arduino and microcontroller dev boards, USB-connected DVRs, and test equipment. It does not support USB 3.x SuperSpeed — if your peripheral has a USB 3.0 Type-B port and your workflow demands SuperSpeed throughput (e.g., high-volume document scanning above ~40 MB/s), you need a USB-A-to-USB-B 3.0 cable or a USB-C-to-USB-B 3.1 cable instead. For most printer and scanner use cases, USB 2.0 is the correct choice because the devices themselves do not exceed 480 Mbps. Pair with a USB hub if you need to connect multiple USB-B peripherals to a single USB-C port simultaneously.

Frequently Asked Questions

Q: Does the USB2CB2M support USB 3.0 or USB 3.1 SuperSpeed data transfer?

A: No. The USB2CB2M is a USB 2.0 cable rated at 480 Mbit/s. It does not support USB 3.x SuperSpeed (5 Gbps) or SuperSpeed+ (10 Gbps). For USB 2.0 peripherals — printers, scanners, most label printers — this is the correct and sufficient spec. If your peripheral requires USB 3.0 speeds, you need a different cable.

Q: Will the USB2CB2M work with a Thunderbolt 3 or Thunderbolt 4 port?

A: Yes, for USB 2.0 data only. Thunderbolt 3 and 4 ports are electrically compatible with USB-C and support USB 2.0 Hi-Speed data transfer. The cable will not enable Thunderbolt-specific features (high-speed storage, daisy-chaining, video over Thunderbolt alt-mode) — it carries USB 2.0 data only.

Q: What is the warranty on the USB2CB2M?

A: StarTech provides a lifetime warranty on the USB2CB2M. If the cable fails due to a manufacturing defect, it is covered for replacement under that warranty.

Q: What devices use a USB Type-B (USB-B) connector?

A: USB Type-B is the square, beveled connector found on most desktop printers, label printers, flatbed scanners, USB-connected DVRs, Arduino and microcontroller development boards, USB audio interfaces, and various industrial instruments. If you see a boxy square port on the peripheral side, it is almost certainly USB-B.

Q: Is an adapter or driver required to use the USB2CB2M?

A: No adapter and no driver are required. USB 2.0 is natively supported by macOS, Windows, Linux, and Chrome OS. Plug the USB-C end into your host and the USB-B end into your peripheral — the operating system handles enumeration automatically.

Q: What is the cable length and is it long enough for a standard desk setup?

A: The USB2CB2M is 6.6 ft (2 m) long. This is adequate for most workstation setups where the peripheral sits on or near the desk and the host is on the desk or floor nearby. For longer runs — across a room or through conduit — passive USB 2.0 cables are limited by the USB spec to 5 m maximum before signal degradation; an active USB extension would be required beyond that.

The StarTech USB2CB2M comes up constantly in deployments where a facility has updated workstations or laptops to USB-C — either because the hardware vendor dropped USB-A entirely or because a docking station only exposes USB-C — but the printers, label applicators, or USB-connected DVRs still ship with USB-B ports. The 22 AWG power conductors are the spec I look at first for anything with a motor or heater on bus power; undersized power conductors cause intermittent resets on label printers during print head warm-up, and that is a hard problem to diagnose on a warehouse floor.

Technical Highlights:

• 480 Mbit/s USB 2.0: Matches the native throughput ceiling of USB-B peripherals — no bottleneck introduced, and no cost premium for USB 3.x bandwidth the device cannot use.
• 22/30 AWG construction: Heavier 22 AWG power conductors support stable bus power to motor-driven or thermally demanding peripherals; 30 AWG data conductors keep the cable flexible for routing in tight cable management.
• Lifetime warranty: For a fixed-install cable routed behind furniture or through a cable duct, a lifetime warranty means you are not buying a replacement cable every few years — the USB2CB2M is covered if it fails.

Deployment Considerations:

• At 6.6 ft (2 m), this cable fits most workstation-to-peripheral distances, but confirm your layout before ordering — USB 2.0 passive cables top out at 5 m per spec, so if you need more reach, plan for an active extension rather than daisy-chaining passive cables.
• This cable does not support USB 3.0 SuperSpeed. If your USB-B peripheral has a USB 3.0 port and you are running high-volume document scanning or other throughput-sensitive workflows, verify the device's actual transfer requirements before specifying USB 2.0 cabling.

The USB2CB2M is the right specification for print-station deployments in distribution centers and retail back-of-house environments where USB-C workstations need to drive USB-B label printers or receipt printers — exactly the scenario where a cheap, undersized cable causes more downtime than it saves.
