I have a Bluetooth Tx board that has two cables, one USB and another SPI-USB (SPI-USB converter). They take up 2 USB ports on my Mac/PC. One of the software I am working with cannot handle both cables at once. When it is running I have to physically disconnect the SPI-USB cable. Since I'm running the software remotely, I would like to be able to remotely "disconnect" the SPI-USB cable as well. Is there a managed USB hub/ports that would allow for this? Thanks!
