Vid-214b Amp-pid-7250 Amp-rev-0100 — Usb
This device ID string — USB VID_214B PID_7250 REV_0100 — identifies a specific USB product and revision. Below I review what that identifier implies, how to interpret and troubleshoot it, and practical examples of real-world workflows for users and developers interacting with such a device.

Why that matters
Typical device categories with similar IDs
Hands-on examples
Example: If Device Manager shows VID_214B&PID_7250 and the device appears as “USB Composite Device” or “Unknown,” search vendor resources for a Windows driver that lists VID 0x214B / PID 0x7250. usb vid-214b amp-pid-7250 amp-rev-0100
Example: An embedded sensor with VID_214B PID_7250 may enumerate as /dev/ttyUSB0; a udev rule makes it available as /dev/my_sensor.
Example: After updating to REV_0200, the device may add a virtual COM port and change PID; you’d need to update udev rules and drivers.
Practical troubleshooting checklist
Risk and compatibility notes
Conclusion VID_214B PID_7250 REV_0100 is a concise fingerprint that unlocks driver selection, firmware awareness, and integration steps. For power users and developers, the VID/PID directs where to look for drivers, how to write udev rules or custom USB code, and whether firmware updates or PID changes will require system-side adjustments. Armed with the ID, the practical next steps are: locate vendor documentation or driver packages for VID 0x214B, verify whether REV_0100 needs updating, and set up stable OS-level naming (udev/INF) for reliable access.

The string USB VID-214B & PID-7250 & REV-0100 refers to specific identifiers for a USB device.
Here is the decoded content and what it means:
Vendor ID (VID): 0x214B
Product ID (PID): 0x7250
Revision: 0100
The REV 0100 often indicates a specific firmware version on the USB bridge chip. This particular revision is known for: Why that matters
This VID/PID pattern (VID 0x214B, PID 0x7250) corresponds to a USB audio/interface device from a small vendor that commonly uses the “amp-” prefix in descriptors to indicate an audio amplifier or USB audio interface (external DAC/amp, USB sound card, or portable headphone amplifier). The revision 0x0100 is a typical initial firmware/hardware revision.
Based on the naming convention:
When a computer encounters VID: 214B and PID: 7250, it is almost certainly communicating with a flash memory storage device.
More specifically, this ID pair is frequently associated with Toshiba TransMemory USB sticks or generic flash drives utilizing Toshiba memory controllers. Toshiba (now Kioxia) has long been a dominant player in NAND flash memory.
