If the device is not working, the issue is typically a missing or improper driver. Since this is a standard Mass Storage Device, it should use the generic Windows USBSTOR.SYS driver. Method A: Update Drivers via Device Manager Right-click the Start button and select .
: ⭐⭐☆☆☆ (2/5) – Functional but outperformed by competitors in precision and software ecosystem.
In extreme cases where the drive is not recognized, some users manually short pins 29 and 30 on the controller to enter "Test Mode". superuser.com Recommendation:
If your drive is behaving erratically or showing up as an "Unknown USB Device," confirm its identifiers using one of the methods below. Method 1: Using Windows Device Manager usb device id vid 1e3d pid 198a top
Some "16TB" or "2TB" SSDs/thumb drives from discount sites use this Chipsbank ID to trick the OS into reporting a high capacity, while the actual physical storage is much lower (e.g., 32GB or 64GB). Device Recognition: In Linux, it usually appears in ID 1e3d:198a Chipsbank Microelectronics Co., Ltd Flash Disk Troubleshooting and Recovery Steps
: This is the most frequent issue, often triggered by an improper ejection, a power surge, or using a tool like dd or Rufus to create a bootable drive. The controller's internal mapping table becomes corrupted, rendering the drive unable to access the NAND flash memory chips where your data is stored.
More prevalent on drives from the early to mid-2010s, the CBM2098E is often found with MLC (Multi-Level Cell) or TLC memory. One of the most famous cases involves counterfeit "128GB" drives that, when tested with h2testw , reveal their true capacity is only 16GB. The CBM2098 UMPTool is commonly used to attempt a "repair" for such drives. Success stories sometimes involve manually setting the correct flash memory type from a list, like H27UCG8T2E , and scanning for bad blocks to reclaim a smaller, but functional, drive. If the device is not working, the issue
These tools are for advanced users and can permanently "brick" the device if used incorrectly. They are typically used to low-level format the drive and reset the controller. 3. Data Recovery
This specific PID ( 198A ) is commonly associated with a USB 2.0 Flash Drive Controller used in budget-friendly USB sticks. When connected, the system may detect the device as:
If you are still having trouble with this device, let me know: : ⭐⭐☆☆☆ (2/5) – Functional but outperformed by
For a user, encountering this device usually means you've plugged in a generic flash drive. Based on technical databases like DeviceHunt and community reports from USBDev , here is what to expect:
Based on hardware databases and technical logs, here are the common properties for this specific identifier:
The Windows Biometric Framework (WBF) may have crashed. Even if the driver is physically present, the underlying service ( WbioSrvc ) may fail to start.
Open the device case (if safe) and look for a small QFN-32 or QFN-48 chip labeled "CS-" or "CHIPS." If you see "CS198A," you have the right device.
