If you have installed software like Zadig or Arduino drivers, they may have hijacked the device. If OS installs it automatically, check Device Manager/System

Speed Limit: This is a USB 2.0 device capped at 100 Mbps. Even if plugged into a USB 3.0 port, it will not reach Gigabit speeds.

• If OS installs it automatically, check Device Manager/System Report to confirm the driver name.
• If not, search for drivers using the exact VID/PID string (e.g., “VID_0FE6 PID_9900 driver”) or visit the device vendor’s site if known.
• On Windows, you can update the driver via Device Manager → Update driver → Browse my computer or Search automatically.
• On Linux, many devices use built-in kernel drivers (usbserial, cdc-acm, ftdi_sio, cp210x). Check dmesg for which driver attached; if none, try binding to an appropriate driver or load a kernel module: sudo modprobe usbserial vendor=0x0fe6 product=0x9900 (only for compatible generic usbserial).
