Sometimes it gets fixed by cycling the power......SOmetimes I have to pull the USB cable (my camera and filter wheel in particular), wait five seconds, and plug it back in. Is there a device similar to the power controller that will cycle a USB port?
Pegasus Ultimate Power Box will do this and is really good.
I also have one of these (link below), which is quite simply the best USB hub I have every used. I have 2 full frame CMOS cameras, a 1600mm and several guide cameras and this hub handles them all, at the same time, easily. You can cycle all the ports individually and you can also connect it to 2 computers and switch between them. This is a really really useful function for mission critical kit like your observatory roof. Expensive, but well worth it. Also programmable.
