OSBridge
USB File Transfer Between Devices
Transfer files between your mobile devices and computers using a direct USB connection with OSBridge. Connect your Android or iPhone to your Mac or Windows PC, enable the required device connection settings, and let OSBridge detect your device for wired file transfers.
Transfer Files Directly Over USB
Wireless file transfer is convenient, but sometimes a wired connection is the better choice. OSBridge lets you transfer files between supported Android, iPhone, Mac, and Windows devices using a USB connection.
A wired connection can be useful when you want a direct connection between devices, when wireless transfer isn't convenient, or when you are moving larger files.
Connect your device with a compatible USB cable, complete the required device authorization or USB settings, and OSBridge can detect the connected device and begin the transfer.
How USB File Transfer Works with OSBridge
USB file transfer with OSBridge is designed to be simple.
- Connect your device: Connect your Android phone or iPhone to your Mac or Windows computer using a compatible USB cable.
-
Enable the required USB settings: Depending on your device and
operating system, you may need to enable the required USB, developer, or
device-authorization settings before OSBridge can detect the device. For Android
devices, this may include enabling USB debugging and approving the computer when
prompted. For iPhone, follow the device-specific authorization and connection
instructions shown by OSBridge or your operating system.
Important: The required settings can differ between Android and iPhone. Follow the instructions displayed for your specific device.
- Allow device access: If your device asks you to trust, authorize, or allow the connected computer, approve the request. OSBridge needs the appropriate device authorization before it can detect the connected mobile device.
- Select your files: Once your device is detected, choose the files or folders you want to transfer.
- Start the transfer: Start the transfer directly between your connected devices. Your files are transferred through the USB connection instead of being uploaded to a cloud storage service.
USB File Transfer from Android
OSBridge supports USB file transfer between Android devices and supported Mac or Windows computers. A USB connection can be useful for transferring photos, videos, documents, downloads, archives, and other supported files.
How to connect Android with USB
- Connect your Android device using a USB cable.
- Enable the required USB debugging/developer settings if OSBridge requires them.
- Select the appropriate USB mode when prompted.
- Approve the computer/device authorization request.
- Open OSBridge.
- Wait for your Android device to be detected.
- Select the files you want to transfer.
- Start the transfer.
Android USB debugging
For some OSBridge USB workflows, USB debugging must be enabled before the Android device can be detected. Android may also display an authorization prompt asking whether you trust or allow the connected computer. Only approve the connection if you recognize the computer you are connecting to.
How to enable USB Debugging on Android:
- Open your Android device's Settings app and go to About phone.
- Tap Build number 7 times until you see a message saying you are a developer.
- Go back to the main Settings menu (or System settings) and navigate to Developer options.
- Scroll down and toggle on USB debugging.
- Connect your phone to the computer. When prompted to "Allow USB debugging", tap OK or Allow.
USB File Transfer from iPhone
OSBridge also supports USB-based file transfer workflows with supported iPhone devices. Connect your iPhone to your Mac or Windows computer using a compatible USB cable and complete the required device authorization steps.
Depending on your device and operating system, you may need to:
- Connect your iPhone using USB.
- Unlock your iPhone.
- Approve the required trust or authorization prompt.
- Enable any required connection/developer setting supported by your OSBridge workflow.
- Open OSBridge.
- Wait for the iPhone to be detected.
- Select the files you want to transfer.
- Start the transfer.
iPhone connection requirements
The exact USB permissions and authorization steps can vary depending on the iPhone, operating system, and OSBridge version.
How to authorize the connection on iPhone:
Unlike Android, iOS does not have standard "USB debugging". Instead, it relies on device trust and (on modern iOS versions) Developer Mode.
- Connect your iPhone to the computer using a compatible USB cable.
- Unlock your iPhone to trigger the "Trust This Computer?" prompt.
- Tap Trust and enter your device passcode.
- (If required by your OSBridge workflow on iOS 16+) Go to Settings > Privacy & Security > Developer Mode. Toggle it on, restart your device, and tap Turn On when prompted.
If your iPhone is not detected:
- Make sure the iPhone is unlocked.
- Check that the USB cable supports data transfer.
- Reconnect the cable.
- Approve any trust or authorization prompt.
- Check the required OSBridge device settings.
- Restart OSBridge and reconnect the device.
USB File Transfer on Mac and Windows
Use OSBridge to connect supported mobile devices to your Mac or Windows PC using USB. This can be useful when you want to move photos, transfer videos, copy documents, or move large files using a wired connection.
Connect the device, complete the required authorization steps, and open OSBridge to begin transferring files from your phone to PC, or PC to phone.

Connect your phone using USB, authorize the connection, select the files on your computer, and start the transfer. This is useful for moving documents, videos, photos, ZIP files, project files, and other supported files.
Why Use USB File Transfer?

USB File Transfer vs Wireless File Transfer
OSBridge supports both USB and wireless file transfer.
| Feature | USB Transfer | Wireless Transfer |
|---|---|---|
| Physical cable | Required | Not required |
| Local transfer | ✓ | ✓ |
| Works without Wi-Fi | ✓ | Depends on connection |
| Easy device setup | Requires USB authorization | Simple pairing |
| Large file transfers | ✓ | ✓ |
| Mobile-to-computer transfer | ✓ | ✓ |
| Computer-to-mobile transfer | ✓ | ✓ |
Which should you use?
Use USB transfer when you want a direct wired connection or when wireless transfer isn't convenient. Use wireless transfer when you want to move files without connecting a cable. OSBridge gives you both options.
Troubleshooting: USB Device Not Detected?
If OSBridge doesn't detect your connected device, check the following:
- Check your USB cable: Make sure the cable supports data transfer. Some cables are designed primarily for charging and may not support data communication.
- Unlock your phone: Keep your Android or iPhone unlocked while establishing the connection.
- Check USB settings: Make sure the required USB, developer, or device-authorization settings are enabled. For Android, check that USB debugging is enabled if required by your OSBridge workflow.
- Approve authorization prompts: Your phone may ask you to trust or authorize the connected computer. Approve the request if you recognize the computer.
- Reconnect the device: Disconnect the USB cable, wait a few seconds, and reconnect it.
- Try another USB port: If your computer has multiple USB ports, try another port.
- Restart OSBridge: Close and reopen OSBridge, then reconnect your device.
