Fixing TUSB1064RNQR Device Not Responding to USB Requests

Troubleshooting the TUSB1064RNQR Device Not Responding to USB Requests

The TUSB1064RNQR is a USB 3.0 hub controller typically used for expanding USB ports and improving data throughput. When encountering the "Device Not Responding to USB Requests" issue with the TUSB1064RNQR, it could be caused by several factors. Below, we’ll analyze possible causes and provide step-by-step solutions to help you resolve the issue.

Possible Causes of the Issue

Driver Issues The most common cause of USB devices not responding is a driver-related problem. If the TUSB1064RNQR driver is outdated, incompatible, or missing, the device will fail to communicate properly with the system. Power Supply Problems USB hubs and controllers rely on sufficient power to function properly. Insufficient power supply to the TUSB1064RNQR can cause the device to fail to respond to USB requests. Faulty Hardware or Connection Physical damage to the TUSB1064RNQR chip, faulty USB cables, or loose connections can disrupt the data flow and lead to the device not responding. Incorrect USB Port or Configuration Using the wrong type of USB port (e.g., connecting a USB 3.0 device to a USB 2.0 port) or incorrect configuration in the system settings can cause communication failures with the TUSB1064RNQR. Software Conflicts Conflicts between different software or other USB devices can also prevent the TUSB1064RNQR from responding correctly to requests.

Steps to Resolve the Issue

1. Check for Driver Issues Step 1: Open Device Manager (right-click on the Start button and select "Device Manager"). Step 2: Locate the Universal Serial Bus controllers section and find the TUSB1064RNQR device. Step 3: Right-click on it and select Update Driver. Choose Search automatically for updated driver software. Step 4: If Windows doesn't find a new driver, go to the official Texas Instruments website, search for the TUSB1064RNQR driver, and install the latest version manually. 2. Ensure Proper Power Supply Step 1: Make sure your USB hub or controller is receiving adequate power. If you’re using a powered USB hub, verify it is plugged into a working outlet. Step 2: If the TUSB1064RNQR is powered directly from the motherboard, ensure that the power supply is stable. You may need to check your system’s power supply or use a different port. Step 3: For high-power USB devices, ensure your PC’s USB ports can deliver enough power, or consider using a powered USB hub. 3. Inspect Hardware and Connections Step 1: Check for any visible damage to the TUSB1064RNQR or the USB cables. Step 2: Make sure that the USB cable is securely connected to both the device and the hub or computer. Step 3: Test the TUSB1064RNQR with a different USB cable to rule out issues with the cable. Step 4: Try plugging the device into a different USB port, especially if you suspect a port issue. 4. Verify USB Port Compatibility Step 1: Confirm that you are using the correct type of USB port for your device. For instance, connect USB 3.0 devices to USB 3.0 ports to take advantage of higher data transfer rates. Step 2: In case of using multiple USB hubs, ensure they are correctly configured and powered. 5. Address Software Conflicts Step 1: Temporarily disconnect all other USB devices and check if the TUSB1064RNQR starts responding. Step 2: Disable any third-party software that might be interfering with USB communication, such as USB management tools or security software. Step 3: Restart your computer and test the device again. 6. Check System BIOS/UEFI Settings Step 1: Restart your computer and enter the BIOS/UEFI setup (usually by pressing the DEL or F2 key). Step 2: Look for any USB-related settings and ensure they are enabled, including options for USB 3.0 support and legacy USB support. Step 3: Save changes and exit the BIOS/UEFI setup. Restart the system. 7. Perform System Restore or Reset If the issue started recently, performing a system restore to a point when the TUSB1064RNQR was working properly might help. Step 1: Open Control Panel > Recovery > Open System Restore. Step 2: Follow the on-screen instructions to restore your system to an earlier state. 8. Update the System BIOS In some cases, updating the system BIOS can resolve compatibility issues with USB devices. Step 1: Visit the motherboard manufacturer’s website and check if there is a newer version of the BIOS. Step 2: Follow the instructions provided by the manufacturer to update the BIOS.
