Frequently Asked Questions


When you troubleshoot issues with a USB On-The-Go (OTG) cable or adapter, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Mobile device

  • USB peripheral

  • Attached media

To test your setup components, try the following:

  • Use the OTG cable, USB peripherals(s), and attached media with another mobile device to see if the problem is with the components or the mobile device.

  • Test the attached media on a computer system.

  • Use a different mobile device, USB peripheral, and USB media in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

If a USB storage device is not detected, make sure that the following is true:

  • The mobile device is compatible with OTG by verifying the mobile device's technical specifications.

  • The USB storage device is using a file system that is compatible with your mobile device (for example, NTFS).

  • The mobile device detects the USB storage device in a file browser (for example, Android File Manager).

If there are USB peripherals attached, such as hubs or adapters, make sure that the following is true:

  • The USB peripherals have drivers compatible with the operating system of the mobile device.

  • The USB peripherals are kept to a minimum and used only when necessary.

Before You Buy

USB On-The-GO (OTG) allows mobile devices to act as a host for USB peripherals. To use OTG with a mobile device using a micro-USB connector, you need to use an OTG adapter to convert from the mobile device to USB.

Although many mobile devices use the micro-USB connector and the OTG adapters plug into your mobile device, the mobile device must have OTG support. OTG support is a hardware specification on your mobile device and cannot be resolved using updates of any kind.

To determine if your mobile device is OTG compliant, refer to the technical specifications of your mobile device.

Odd wiring?

By: Confused - 04/16/2020
At the Micro-B end of the cable pins 4 & 5 (ID & GND) are shorted as expected for OTG, but at the Mini-B end of the cable pin 5 is not connected to anything. I can't find any reference to this type of pinout and expected pin 5 to be 0V / Gnd at both ends. A pinout drawing in the StarTech datasheet would really have helped before I bought these! :-(

We apologize for any confusion when purchasing our UMUSBOTG8IN. This cable combines pins 4 and 5 from the Micro-USB side to pin 4 on the Mini-USB side. We have a technical diagram with the pinout available and we'd be happy to provide it to you. If you have any questions or would like any assistance, please do not hesitate to contact us at where our Technical Advisors are available 24 hours a day, 5 days a week.
