13fe Usb Disk 50x Usb Device !!install!! Jun 2026
However, in this specific error case, the device is failing to communicate properly. The "50X" indicates that the controller is operating in a "fallback" or "factory" mode, unable to access the user data partition. The "13fe" identifies the manufacturer of the controller chip inside the drive, which is . While Kingston outsources controllers from Phison, this identifier is tied to the chip maker, not the brand of the USB casing.
The controller software is corrupted, making the drive unreadable. Troubleshooting: How to Fix 13FE USB DISK 50X
If your computer labels a device "50x USB Device," it has likely identified the internal bridge chip—the piece of hardware translating between the USB cable and the storage memory—rather than the storage device itself.
If the data is expendable, here is the typical troubleshooting hierarchy: 13fe usb disk 50x usb device
On Linux, the identifier appears in tools like lsusb , dmesg , and Disks ( gnome-disk-utility ). A common symptom is the drive being recognized but reported as having "No Media" [22†L4-L5].
Open the MPTool configuration, load the correct firmware files, and execute a low-level flash.
Your drive usually shifts into this emergency fallback state due to one of three common triggers: However, in this specific error case, the device

Knowing these details will help determine if the drive can be salvaged or if it needs to be replaced. Share public link
While there are fewer specific reports for macOS, the same underlying principles apply. The drive may appear in but show as "Uninitialized" or with a generic identifier like "13FE USB DISK 50X" [1†L27-L29]. If the data is expendable, here is the
This issue is not limited to Windows. On systems, running lsusb in the terminal will directly display ID 13fe:5000 or ID 13fe:6700 with a descriptor of "USB DISK 50X". The kernel logs (via dmesg ) will often show the device being detected but failing to mount due to "I/O errors" or "Medium not found". Similarly, on macOS , Disk Utility will list the device but show "No Media" and a capacity of zero, often accompanied by a "This disk is not readable" error.
A "32GB" labeled drive often reports a usable capacity of roughly 28.87 GB . Common Issues and Troubleshooting
The is a technical identifier that appears in Windows Device Manager and Diskpart when a USB flash drive built with a Phison Electronics controller experiences a critical firmware or hardware failure. The string 13FE represents the specific USB Vendor ID (VID) for Phison, while 50X indicates a generic fallback hardware state. When a flash drive exhibits this name, it typically pairs with a frustrating "No Media" status, rendering the drive completely inaccessible with a capacity reading of 0 bytes.
