Windows cannot find the generic mass storage driver.

If you're having trouble with a VID 1E3D PID 198A drive, you may need specialized Chipsbank USB tools like or UMPTool . These utilities are designed for low-level formatting and firmware reflashing. For standard troubleshooting, you can try:

This is a low-end, generic controller often associated with counterfeit storage . If you own one, verify its true capacity with tools like H2testw before use.

High Speed (theoretical max of 480 Mbps), though real-world write speeds often hover between 3–17 MB/sec. Current Draw: Max 100mA.

Since this is a Chipsbank device, standard formatting tools often fail. Specialist technical communities often point to "Mass Production Tools" (MPTools) specifically designed for Chipsbank controllers:

A: You have likely purchased a counterfeit drive. The controller is programmed to report a larger capacity (e.g., 128GB) than the physical NAND flash chip (e.g., 16GB). Use H2testw to verify the true size.

: Described as "HighSpeed" under the USB 2.0 protocol, though actual speeds depend on the specific flash memory chip paired with the Chipsbank controller. The "Chipsbank Experience": A Review
