USB Flash Drive Speed Tests - VID = 1e3d, PID = 198a - NirSoft
Note: These chips often find their way into counterfeit or spoofed-capacity drives. A drive programmed to display "256 GB" in Windows might physically only possess 8 GB or 16 GB of actual NAND flash storage. Common Failures and Errors USB Flash Drive Speed Tests - VID = 1e3d, PID = 198a
Since this chip is often used in OEM products, visit the support page of your laptop brand (Chuwi, Teclast, etc.) and download the "Fingerprint Driver" or "Touchpad Driver" package specific to your exact model. Usb Device Id Vid 1e3d Pid 198a
The identifiers "VID 1E3D" and "PID 198A" are USB Vendor ID (VID) and Product ID (PID) values used by an operating system to recognize a specific USB device. Together they uniquely identify the manufacturer (VID) and the product model (PID) so the OS can load the correct driver or take an appropriate action.
If the drive is showing as "No Media" or "RAW" in file explorer, use NirSoft USBDeview to manage it, or use diskpart: Open Command Prompt as Administrator. Type diskpart . Type list disk . Identify the disk number of your USB drive. Type select disk X (replace X with your disk number). Type clean . Type create partition primary . Type format fs=ntfs quick .
When you connect a USB device to a computer, the operating system uses the VID and PID to identify the device and install the appropriate driver. Chipsbank Microelectronics Co
if:
The drive locks into a permanent read-only state. Any attempt to write data, delete files, or apply a format returns a "The disk is write-protected" error. This is a safety mechanism triggered by the controller when it detects bad sectors exceeding its error-correction capabilities. 3. Controller Hang-ups after Bootable Tool Deployment
:
⚠️ Flashing the controller completely destroys all data stored on the flash drive memory chips. If you need file recovery, you must use data recovery software before initiating this process.
Older PCs with native USB 2.0 host controllers often work better with CBM2099 drives. Newer USB 3.x hosts (especially on laptops) may enter UAS (USB Attached SCSI) mode, which the CBM2099 does not fully support. Force legacy USB mode in BIOS if possible.
When you plug in a device, the operating system reads this combination to load the correct driver. If the VID/PID pair is altered or generic, it can cause connection and performance issues. The hardware ID for this device in Windows is often displayed as USB\VID_1E3D&PID_198A , following the standard format defined by Microsoft. Common Failures and Errors USB Flash Drive Speed
