UGREEN 30767 2-PC 4-Port USB 2.0 Sharing Switch
A two-computer USB peripheral switch that lets either selected host use up to four connected USB-A devices. One front-panel button changes ownership, two indicators identify the active computer, and the USB 2.0 path supports up to 480Mbps theoretical across the shared peripheral connection.
Product overview
Overview
UGREEN 30767 has two rear USB-A host inputs and four front USB-A peripheral ports. The supplied USB-A-to-A host cables connect each computer to a dedicated input; the button selects one input at a time. Switching logically disconnects the devices from one host and reconnects them to the other.
The shared data standard is USB 2.0 with an interface ceiling of 480Mbps. This model is intended for normal USB 2.0 peripherals rather than high-speed SSD workloads. Bandwidth is shared by the simultaneously active peripherals, and printers, scanners, storage and specialist devices can remain limited by their own interface, driver or application.
A rear Micro-USB 5V input can supply auxiliary power when several peripherals or a higher-draw device exceeds what the selected host path reliably provides. The exact package image does not show a Micro-USB power cable or wall adapter, so a separate regulated 5V source and suitable cable are required if auxiliary power is used.
Verified highlights
Key features
- Two-host sharing: connect two computers and select one active host at a time.
- Four peripheral ports: share up to four USB-A devices through the USB 2.0 switch.
- Data ceiling: up to 480Mbps theoretical for a complete compatible path; practical bandwidth is shared.
- Manual control: one physical button changes the active host; there is no automatic or simultaneous control mode.
- Visible state: two LED indicators identify which computer currently owns the peripherals.
- Optional auxiliary power: Micro-USB 5V input supports demanding setups when used with a separate regulated source.
- Host cabling: two USB-A-to-A data cables are included; no cable length is asserted because the exact package graphic does not specify it.
- Driver-transparent switch: the switch normally needs no special utility, while every peripheral must work on both computers.
Know the exact connector roles
Host inputs, peripheral outputs and power map
The rear computer inputs and front device ports have distinct roles even though they all use USB-A sockets. Use only the included host cables for the computer inputs.
- Computer input 1: rear USB-A socket linked to host 1 by one included USB-A-to-A cable.
- Computer input 2: rear USB-A socket linked to host 2 by the second included USB-A-to-A cable.
- Four peripheral outputs: front USB 2.0 USB-A sockets for compatible printer, scanner, mouse, keyboard, receiver or storage devices.
- Selection button: transfers the four-port device group between computer 1 and computer 2.
- Two LEDs: indicate the selected host; they do not show file-write completion or peripheral health.
- Micro-USB 5V input: accepts auxiliary power only from a regulated 5V source; it is not a high-voltage charging input.
- Separate displays: monitor cables shown in use imagery remain directly connected to the computers or a separate display switch.
Where it makes sense
Use scenarios
The switch is useful where two computers take turns using the same desk peripherals and manual selection is acceptable.
- Share one USB printer and scanner between a work computer and home computer without repeatedly moving their data cables.
- Move a wired keyboard, mouse and USB receiver as a group between two nearby desktops or notebooks.
- Use a USB audio interface, webcam or specialty controller only after confirming that both host operating systems support its driver and reconnect behavior.
- Share an external storage device for occasional transfer, safely ejecting from the active computer before every switch.
- Connect up to four low-power desk peripherals, adding regulated 5V auxiliary power if the selected host cannot supply the total load.
- Pair with a separate monitor input selector or KVM display path when the goal is a complete two-computer desk; this unit handles USB only.
A dependable first connection
Setup and usability guidance
Connect and test one host and one peripheral first. Add the second host and remaining devices only after the basic switching path is stable.
- Install and test each printer, scanner or specialist device directly on both computers so its driver and application are ready.
- Place the switch where the button and LEDs are visible, then connect computer 1 and computer 2 to the rear inputs with the two included USB-A-to-A host cables.
- Connect a keyboard or mouse to a front peripheral port and press the button to verify that only the selected computer controls it.
- Add the remaining USB peripherals one at a time, checking detection on both hosts after each addition.
- If multiple devices disconnect or a storage drive cannot start, connect a separate regulated 5V Micro-USB power source; do not use an incompatible voltage.
- For a storage device, eject/unmount it and wait for writes to finish before pressing the selection button.
- Keep displays, network and analogue audio connected separately, then label the two host inputs if the computers look similar.
Match the whole chain
Compatible devices and systems
Both hosts must support the peripheral through their own operating system, driver and application. The switch changes the physical USB path; it does not translate drivers.
- Desktop and notebook computers with a USB-A host port compatible with USB 2.0.
- USB-C-only computers through a separate data-capable USB-C-to-USB-A adapter or dock.
- Standard keyboards, mice, receivers, printers, scanners and other class-compliant USB peripherals.
- External storage and card readers at up to the 480Mbps shared interface ceiling, subject to power, filesystem and safe-removal behavior.
- Webcams, audio interfaces, controllers and licensed/security peripherals only when they tolerate logical disconnect/reconnect and have drivers on both hosts.
- Windows, macOS, Linux and other systems that normally support the attached devices; side buttons and vendor utilities may behave differently.
- Powered peripherals or a separately powered hub only when their normal USB topology and current requirements remain within supported limits.
Capabilities
What this product does
- Lets two computers take turns controlling one group of up to four USB-A peripherals.
- Changes the active host with one manual button and identifies it with LED feedback.
- Carries USB 2.0 data up to 480Mbps theoretical on a complete compatible path.
- Uses two included USB-A-to-A host data cables for the rear computer inputs.
- Offers a 5V Micro-USB auxiliary power input for demanding multi-device combinations.
- Reconnects ordinary USB peripherals without requiring a dedicated switching application.
Clear boundaries
What this product does not do
- It does not let both computers control the peripherals simultaneously.
- It does not switch automatically on keyboard activity, computer wake or operating-system state.
- It does not carry HDMI, DisplayPort, VGA or any monitor signal and is not a complete display KVM.
- It does not switch Ethernet, Wi-Fi, analogue audio or USB-C Power Delivery.
- It does not charge phones or laptops as its intended function; the Micro-USB socket is a 5V auxiliary input.
- It does not make a peripheral driver-compatible with an operating system that does not support it.
- It does not guarantee safe live switching of mounted storage; ejection remains required.
Good practice
What to do
- Use the two included USB-A-to-A cables only between the designated rear host inputs and the two computers.
- Install the peripheral drivers on both systems and test each device before relying on the switch.
- Eject storage and close scanner, camera or audio applications before transferring device ownership.
- Add a regulated 5V Micro-USB power source when the total connected load is unstable or the device maker requires more power.
- Keep host and peripheral leads short, undamaged and strain-relieved; test directly before adding hubs or extensions.
- Label the selection LEDs/host numbers and save work before changing devices used by active applications.
Avoid these mistakes
What not to do
- Do not connect two computers to the front peripheral ports or use a random A-to-A cable outside the designated host inputs.
- Do not press the switch while a storage volume is writing, a print/scan job is active or device firmware is updating.
- Do not connect a high-voltage quick charger to the 5V Micro-USB input or improvise a power-injection cable.
- Do not expect monitor switching because two displays appear in an illustration; their video paths are separate.
- Do not exceed the combined current available from the selected host and any correctly connected auxiliary supply.
- Do not assume reconnect-sensitive licensing keys, audio streams, webcams or controllers will resume seamlessly in every application.
Important safety and performance notes
Warnings and limitations
Pressing the button is equivalent to unplugging the whole peripheral group from one computer and plugging it into the other. Prepare active devices first.
- Unsafely switching mounted storage can corrupt open files or the filesystem. Eject and wait for all activity to finish.
- The 480Mbps figure is a shared theoretical link ceiling, not a per-port guarantee. Simultaneous devices compete for bandwidth.
- Printers, scanners and specialty devices can hold jobs or locks in software; close their applications before switching.
- Auxiliary power must be regulated 5V through Micro-USB. Wrong voltage, polarity or a damaged cable can harm connected equipment.
- A powered device may backfeed or violate topology if connected through an unsuitable hub/cable. Use normal standards-compliant peripherals only.
- USB reconnect events may wake a computer, change default audio devices or reassign drive letters depending on the operating system.
- Stop using the switch if a port is loose, the housing becomes abnormally hot or any cable causes intermittent connection when touched.
Keep it working and solve common issues
Care, troubleshooting and buying checklist
Test in layers: one known keyboard, one host cable, one computer input, then the second host and remaining peripherals.
- No LEDs or devices: reseat the selected host cable, confirm the computer USB port works and add regulated 5V auxiliary power if needed.
- One computer works: swap the two included host cables and rear inputs to determine whether the cable, host port or input is responsible.
- Printer/scanner missing: install its driver on both hosts, close the vendor application before switching and allow reconnect time.
- Storage is slow: check that host, cable and drive match USB 2.0; the shared 480Mbps ceiling is divided by simultaneous traffic.
- Storage disconnects: use a separately powered compatible drive or regulated 5V auxiliary input and eliminate long extensions.
- Mouse/keyboard lag: move 2.4GHz receivers away from noisy USB hardware, shorten cables and test without high-bandwidth devices.
- Buying check: confirm two computers, no need for monitor switching, four or fewer USB-A peripherals and acceptance of manual one-host-at-a-time control.
