Some vendors using the same chip had an unacceptable performance and are listed as unsupported.

Performance is primarily determined by a combination of the chip and the Linux drivers for the adapter. High-performance determination methodology These adapters are connected via the UART bus which may limit their performance. Most of these adapters can hold seven (7) connections at the same time. There is currently no supported method to install these patch files when using Home Assistant Operating System. These adapters may require additional patch files available at for stable operation. These adapters generally offer the fastest connect times and do not require additional drivers or patch files. Most of these adapters can hold five (5) connections at the same time.
