Does detect a specific chip controller manufacturer name?
Based on the manufacturer profile (Shenzhen Feitian) and the hardware typically associated with this VID, your unknown device is likely one of the following three things:
For software engineers, system admins, or Linux developers mapping custom udev rules, here is the technical summary block for this device: 08 (Mass Storage Device) USB Subclass: 06 (SCSI Transparent Command Set) USB Protocol: 50 (Bulk-Only Transport - BBB) Reported Device Power: 100mA Common Linux Kernel Module: usb-storage

Hardware tracking data gathered from benchmark tools like NirSoft USBDeview details the typical real-world speeds for these controllers: ~15 MB/s to 20 MB/s Sequential Write Speed: ~4.5 MB/s to 6.5 MB/s The exFAT Performance Optimization Trick
Because these drives use generic controllers, they are prone to specific software and hardware errors. "USB Device Not Recognized" (Code 28 or 43)
Expand the section (or check under Other Devices if there is a yellow exclamation mark).
If you are "preparing a paper" on this device—likely for a technical report, performance log, or documentation—here is the essential data to include: Device Specifications Vendor ID (VID): (Typically linked to or generic Chinese manufacturers) Product ID (PID): (Standard generic product code) Controller: Often identified as FirstChip FC1178BC USB 2.0 (High Speed) Standard Performance: Read Speeds: 10–25 MB/s Write Speeds: 3–10 MB/s Performance Optimization
Plug the drive directly into the motherboard ports located on the back of a desktop computer. Front panel ports and unpowered hubs often deliver unstable voltage.
