Why ASUS EZ-Flash Can’t See USB Drive
According to a survey, the main reason for the “ASUS EZ-Flash not detecting USB” issue is an incompatible file system. If the USB drive is not formatted to FAT32, it cannot be detected by the utility. Besides, other factors like faulty USB ports, improper operation, and an outdated driver are also responsible for the problem.
How to Fix ASUS EZ-Flash Not Seeing USB Drive on Windows 10/11
You can try the following 5 methods to fix the “USB drive is not showing up in ASUS EZ-Flash” issue. Here I recommend you try them one by one until the problem gets fixed.
Fix 1. Use a Different USB Flash Drive
Some users found that the ASUS EZ-Flash doesn’t see USB drive when using certain brands or older flash drives. To fix the issue, you can try using a larger/smaller or different brands of USB drive, and make sure it is formatted to FAT16/FAT32.
Fix 2. Plug the USB into Another Port
In most cases, a computer usually has multiple USB ports that are compatible with different USB flash drives. ASUS EZ-Flash doesn’t see USB drive if the port gets damaged or is not compatible with the drive. So, I recommend you plug the USB into a different port and see if it works. If it still doesn’t work, proceed with the following fixes.
Fix 3. Format the USB Drive to FAT32
One of main reasons for the ASUS EZ-Flash not seeing USB drive problem is an incompatible file system. You need to format the USB to FAT32 beforehand using an FAT32 formatter. Although you can format it using Disk Management or DiskPart, these tools have limitations when formatting a USB larger than 32GB to FAT32.
So, I highly recommend you use an expert formatter – MiniTool Partition Wizard. It can format your USB to FAT16/FAT32/NTFS/exFAT/Ext without limitations. With the tool, you also can convert NTFS To FAT32 without data loss, change cluster size, clone hard drives, migrate OS, rebuild MBR, convert MBR to GPT, recover data, and more.

Step 4. Click on OK > Apply to start formatting the USB.

Fix 4. Update the USB Driver
As discussed above, an outdated device driver is one of the reasons why the USB drive is not showing up in ASUS EZ-Flash. So, I suggest you update the USB driver to the latest version. Here’s how:
