Another way of trying to tackle the problem is to reduce as much as possible the need to use a recycling capable hub. I ran a fine offset station for maybe 5 years and had I think one lock up in that time. I did however use a powered hub and good uprated power supplies for RPi and hub, and ensured all leads went nowhere near power supplies, computers, screens etc. I minimised all loads on the rpi as much as possible. It definitely worked for me and I never felt the need to go investigating the switchable hub option, so always managed to upgrade the OS without any issues.
