Update/Reinstall Logitech Gaming Software
Some errors with the official Logitech Gaming Software can lead to malfunctioning hardware. Updating the software or reinstalling them completely can solve these issues.
Replace USB Wireless Transceiver
USB wireless transceiver is a small pen drive-type device when connected, sends and receives data to and from your headphones. This is also called a 2.4GHz wireless feature. On Logitech G933, this adapter is located inside the left ear cup.
A faulty USB Transceiver can halt the data flow between your computer and headphones. If this is the case, replacing this transceiver can solve the problem.
Replace the Charging Cable
Another reason the Logitech G933 is not charging is a damaged charging cable. Logitech G933 uses a USB mini port to charge, which can get damaged fairly easily. If you cannot get the headphones to charge, the charging cable may be at fault.
Update USB Driver
The Logitech G933 uses a USB transceiver to send and receive data between the computer and the headphone itself. This USB transceiver is connected to one of the USB ports in your computer. Therefore, if this driver is not up-to-date, it cannot communicate with the Operating System.
To update the USB driver, follow these steps.
Press the Windows + X key and go to Device Manager. Expand Universal Serial Bus Controllers, then right-click and update everything inside it. Expand the USB Controller Manager, then right-click and update everything inside it.
Restart your computer after the update is complete.
Problems with Logitech G933
If none of the above solutions work, then the issue might be with the Logitech G933 itself. For example, the headphones will not charge if the USB-mini port is damaged. You can also take your headphones to a local electronic repair shop.
