A: Yes. The current CH340 drivers fully support 64-bit versions of Windows, macOS, and Linux. A: Yes

Linux has built-in kernel modules for both chipsets. No manual download is required for most distributions. The HW-597 driver is included in the kernel as:

They called it hw-597 — a small, humming thing of solder and soft logic hidden inside the belly of an older machine. To some it was just a driver file, a stitched-together map of zeros and ones that told metal how to remember; to others it felt like a key, a tiny poem that wakes sleeping gears.

Cause: Driver conflict or corrupted installation.
Fix: Uninstall the driver via Device Manager (right-click → Uninstall device, check “Delete driver software”). Then reinstall the driver and reboot.
