Based on the provided string, here's a feature: vid = 1e3d pid = 198a

A hobbyist buys a $2 “USB‑to‑SPI/I2C/UART” module from AliExpress. Plugging it in, lsusb shows 1e3d:198a . They write a Python script using pyusb or libusb to bit‑bang an I2C EEPROM – successfully dumping the config of a dead laptop’s battery. The 198a PID is less common than the

lsusb -d 1e3d:198a -v

The fix is almost always a driver issue. Don't rely on Windows Update; go to the source, grab the Virtual COM drivers, and your "Unknown Device" will transform into the reliable COM port you need. Plugging it in, lsusb shows 1e3d:198a
