The editors at Electronic Design had never seen a programmable USB hub before, so we sent one of the Acroname USBHub3+ units to them for evaluation. The team at ED mentioned how simple USBHub3+ is to use and particularly how it would enhance USB product testing or manufacturing environments.
Come take a look at their detailed review here:

The BrainStem scratchpad is a shared memory on a brainstem module which is accessible from both the host and Reflex code. It serves as a simple interprocess communication channel for separate Reflex routines, as well as a communication channel between the host and reflex code running on the BrainStem module.
For everyday use — like connecting a mouse or webcam to your laptop — an inexpensive USB hub with enough ports will get the job done. However, in production or test environments, robustness and reliability are paramount. Chasing bugs inherent in inexpensive USB hubs is distracting and time-consuming, and failed processes can shut down lines or negatively impact your product quality. Even worse, a cheap hub may be able to damage your critical production systems.
Acroname's BrainStem® technology is a foundational tool for bridging the gap between hardware and software systems. BrainStem controllers gather and relay peripheral information to other systems, which may be a host computer, additional microcontrollers or an array of sensors and testing equipment.
One common task in designing and building automation systems is logic circuitry interfacing to high power loads. Read article.
PWM (Pulse Width Modulation) refers to the concept of rapidly pulsing a digital signal on a wire. Amongst many other uses, it can be used to simulate a varying static voltage. PWM is commonly used for driving motors, heaters, LEDs or lights in varying intensities or speeds. Read Article
