I had been using another coupler and I was getting less than 100 Mbps speed. Hence I decided to try Ugreen coupler. I had bought a 1000Mbps and this one. Both saved me from the hassle of changing the entire cable.

Features
What it does well.
Key features
Quick reference
length. 2 metres
Data capability. Up to 480Mbps USB 2.0; backward-compatible with USB 1.1/1.0 peripheral operation
Host/source side. USB-C male for a computer, tablet or host that supports USB data
Device/downstream side. USB 2.0 Type-B male for a printer, scanner, piano, DAC or other peripheral
How it fits into your setup
Connections and roles
Host or source. USB-C male for a computer, tablet or host that supports USB data
Peripheral or downstream side. USB 2.0 Type-B male for a printer, scanner, piano, DAC or other peripheral
Connection role. USB-C host-to-USB-B peripheral connection; data becomes bidirectional after enumeration
Power expectation. Carries ordinary USB bus power for interface operation; not a charging cable for phones or laptops
Direct USB-C host connection for a standard USB-B peripheral
Real-world performance
The cable avoids a separate USB-C-to-USB-A dongle, reducing one connection point. The computer USB-C port must still support USB data.
480Mbps is the USB 2.0 signalling limit. Print and scan time also depends on the peripheral, driver, application and document.
A nylon-braided jacket, aluminium connector housings, nickel-plated contacts and triple shielding are stated for this model.
Construction and everyday durability
Materials and handling
Construction detail 1. Nylon-braided cable jacket
Construction detail 2. Aluminium-alloy connector housings
Construction detail 3. Nickel-plated USB contacts
Construction detail 4. Triple shielding with molded strain relief
Durability claims describe controlled product testing, not immunity from crushing, repeated sharp bends, liquid, corrosion or worn sockets. Grip the connector housing rather than pulling the cable.
Use scenarios
Where it is useful
Modern laptop to printer. Connect a USB-C-only laptop directly to the square USB-B socket on a supported printer.
Scanner workstation. Use a wired data path for a compatible scanner or multifunction device.
Digital piano or MIDI. Connect supported USB-B music equipment to a USB-C host for MIDI/audio functions provided by the device.
DAC or specialised peripheral. Link a USB-B DAC, camera or other device whose manual supports standard USB 2.0 Type-B.

Setup and usability guidance
Installation workflow
The cable or hub normally has no standalone application. The connected device can still require its manufacturer driver, firmware, print queue, audio/MIDI setting, storage permission or USB mode. A physical connection cannot add a missing operating-system feature.
When troubleshooting, test one variable at a time: a direct host port, a known-good peripheral, the original device cable, an updated driver and a simple workload. This distinguishes cable, power, port and software faults.
Confirm the peripheral uses the square standard USB 2.0 Type-B socket
Connect USB-B to the printer, scanner, piano or DAC
Connect USB-C to a host port that supports USB data
Install the peripheral maker’s driver or application if required
Run a small test job before routing the 2m cable
What to do
Good practice
Verify first. Check SKU, connector, length, role, data generation and power expectation before ordering.
Use a direct path. Remove unnecessary adapters and hubs while installing or diagnosing the connection.
Support the plugs. Leave a gentle service loop and prevent cable weight from pulling on small sockets.
Test before routing. Complete repeated real tasks before hiding the cable behind furniture or inside management channels.
Do not force a near-match. Stop when plug shape or insertion resistance is wrong. Similar USB connectors are not interchangeable.
Do not exceed the stated role. No USB-C DisplayPort Alt Mode or monitor output. Carries ordinary USB bus power for interface operation; not a charging cable for phones or laptops.
Do not stack unknown links. Unsupported extensions and adapters reduce signal and power margin.
Do not ignore heat or damage. Unplug equipment that is wet, frayed, loose, crushed or unusually hot.
Warnings and limitations
Read before use
Performance reminder: advertised USB rates are theoretical ceilings. Real results depend on the slowest compatible component and on shared bandwidth, software, workload and power conditions.
Do not force the plug into the wider USB 3.0 Type-B socket shape
Some USB-C ports are charge-only; verify host/data support
Audio and MIDI equipment can require manufacturer drivers and settings
Do not buy this as a charging or display cable
Keep the braided cable dry and avoid tight bends near connector housings
Troubleshooting by symptom
Diagnose methodically
Not detected. Confirm the connector and port role; test direct without a hub and restart the peripheral.
Connects then drops. Inspect for loose ports or cable strain, simplify the link and reduce bus-power demand.
Transfer is slow. Verify every endpoint supports the advertised USB generation and test with one large file.
Printing or scanning fails. Install the manufacturer driver, select the correct device and clear stalled print/scan jobs.
Works on one computer only. Compare drivers, USB power settings, security permissions and port capability.
Charging is weak or absent. Review the stated power role; this product may be data-focused and cannot add a charging protocol.
Video is absent. Use a dedicated video-capable solution unless this product explicitly supports USB-C display mode.
