When a developer obtained an MVSILICON-based device and tried to use it on Linux, they discovered it had a Vendor ID (1235) that conflicted with audio interfaces from Focusrite. This caused Linux to attempt to load Focusrite's drivers, which failed. To fix this, the developer contributed a patch to the Linux kernel that specifically identifies these devices by their Manufacturer: MV-SILICON string and applies the correct driver behavior. This patch was accepted into the mainline Linux kernel, which means if you keep your Linux system updated, the "software" supporting your B1 is continually improving.
The only exception is the variant, which supports firmware updates via a dedicated SPI programmer. ⚠️ Flashing incorrect firmware can damage your device
