What is the reason for no response when plugging a USB flash drive into the car's USB port?

If the USB flash drive connection shows no response, you can try formatting the USB flash drive and changing its format to see if that helps. The USB port is a type of vehicle transmission cable, featuring fast transmission speed, ease of use, support for hot-swapping, flexible connection, and independent power supply. The reasons why the car USB suddenly fails to read the USB flash drive are as follows: 1. Loose USB flash drive: Since the USB flash drive is plugged into the vehicle's USB port for extended periods during use, the vibration and shaking of the vehicle while driving can easily cause it to become loose. Once loose, the car USB may suddenly fail to read the USB flash drive. 2. Damaged USB flash drive: The possibility of a USB flash drive being damaged is relatively small, but due to the less-than-ideal environment inside the car (especially under high temperatures in summer), the possibility of damage cannot be ruled out. 3. Damaged USB port: The likelihood of the USB port being damaged is believed to be even smaller than that of the USB flash drive. However, when the above assumptions are not the issue, the possibility of a damaged USB port cannot be excluded.
I've encountered this issue when playing music from a USB drive in my car, mainly due to incompatible USB drive formats. Many car systems only support USB drives formatted in FAT32. If your USB drive is in NTFS or exFAT format, the system won't recognize it. Try formatting the USB drive to FAT32 on your computer and then plugging it back in—this often solves the problem. Additionally, a USB drive that's too large might not be recognized; for example, drives over 16GB may require checking if your car supports them, especially older models which have more limitations. Dust or debris in the USB port can interfere with the connection—gently clean it with compressed air or a cotton swab. Another solution is to test with a smaller-capacity USB drive to rule out hardware issues. As a preventive measure, check your car's manual for a list of compatible USB drives before purchasing, and avoid using the USB drive for extended periods when the engine is hot to prevent overheating and shortening its lifespan. After all, in-car entertainment is important, and promptly addressing these minor issues can make your trips more enjoyable.
