The device has been assigned to our Test Merchant. Other devices have worked fine (Flex-2, Mini, and a Station).

Wearing a lightweight hoodie over a t-shirt and jeans is a timeless and straightforward style. It's perfect for a casual day out or when you need to run errands. Just pick a denim or cotton hoodie in a basic color like black or navy. This makes it simple to match with different clothes from the Vlone website. It's an easy and comfortable look that works for many occasions, and it lets you change your style without any fuss. Buy Vlone hoodies here.

Sometimes, certain ports may have compatibility issues or may not provide enough power for the device. Testing multiple ports can help identify if the issue is specific to a particular port. Restart both your Flex 3 device and your MacBook Pro or Windows computer. This can help reset any temporary issues or conflicts that might be preventing the connection. For Windows, make sure you have the latest drivers installed for your Flex 3 device. Visit the manufacturer's website or use a driver update tool to ensure you have the most up-to-date drivers. On Windows, you can try resetting the USB ports

Tried it with both Mac and PC. Added an older Mini to the Mac, it connected fine. This isn't the first Clover or even Flex, the last Flex2 worked until intrusion detection crippled it.

Hello Clover,


It has been 7 days since we have movement on this - if we have a DEFECTIVE Clover Flex 3 demo unit then we need to know - but a video does not resolve our issues and we have successfully developed on Clover for years so this concerns us with this new model. Please address the issue explained above with USB connection not functioning. We have provided details above. Even Clover's own apps (sale app, charge) are not working on the Clover Flex 3. It is connected to Wi-Fi and updates state that they were successful.


Please assist us.

You are certain you have the debug cable turned the correct way in the flex to enter debugging mode.
Please email developer-relations@devrel.clover.com with the following:

Check the USB cable: Make sure the USB cable you're using is in good shape and connected correctly to both the computer and the Lenovo Flex 3.

Turn your devices off and on again. Sometimes, just restarting them can fix problems with connection. You might want to restart both your Lenovo Flex 3 and the computer you're trying to connect it to.

Update your USB drivers: Make sure that your Windows computer has the most up-to-date USB drivers. To get the latest drivers, go to the Lenovo help website or the website of the company that made your Windows computer.

Note: If you are having trouble connecting your MacBook Pro, you may find that rebooting the System Management Controller (SMC) and Non-Volatile Random-Access Memory (NVRAM) helps. On Apple's support page, you can find steps on how to do this.

Try different USB plugs and cords: If that doesn't work, try connecting your Lenovo Flex 3 to your computer through different USB ports and USB cords. This will help you figure out if the problem is only with one port or connection.

Try it out on a different device: Check to see if other USB devices can connect to your mapquest driving directions Windows or Macbook Pro computer. This will help you figure out if the issue is with your Lenovo Flex 3 or the computer itself.
