How can the Device Descriptor Request Failed error be avoided?

This is a typical issue that can occur whenever you connect a new USB device to your PC, but there are a few things you can do to avoid it.

Connect the gadget to the PC directly

We all know that a PC or laptop never has enough USB ports to accommodate all of your gadgets and that it is sometimes necessary to use USB extenders or hubs.

However, these can frequently fail or be incompatible, so connect your USB device straight to an empty port on your machine.

Use the proper port

Although USB ports are backward compatible, your device may not be as adaptable, especially if it is very new or extremely old.

That is why you should try connecting your device to a suitable socket so that it can be recognized and function properly.

Move the port

Although it is rare, USB ports can malfunction from time to time, or they may have accumulated dust and are unable to assure appropriate contact.

So, in addition to gently cleaning the port and connector with a soft brush, try plugging your device into another one and seeing what happens.

However, if this is the case, please read our post on what to do if the USB ports are not working and resolve this issue as soon as possible.
