I have an Intuitive Instruments Exquis connected to the host port of my MKII. Recently, when I turn the E1 on, the Exquis starts corrupted (dim LEDs, random buttons and pads lighting up, nothing works as it should) and I have to do a factory reset. This seems to be since updating to 4.1.1 - it happened very occasionally before but now it happens every time. This doesn’t happen to the Exquis when using other devices with a host port.
It seems like it might be a power issue, although after a factory reset the E1 powers the Exquis perfectly, so perhaps something to do with how it’s connecting and providing power via the host port on boot up?
