I've no spare USB ports for a plugin one.
Hi Peter, I use a USB powered hub at the telescope, plug in all my USB items, including OnStep & a USB Wifi adapter (now only inches/cm from OnStep), and use a 15 ft USB cable attached to a 25ft USB extender cable to setup where it's warmer or has fewer mosquitoes, depending on the season. Last year, I passed the cable thru my car window and sat inside, starting the car occasionally to keep warm.
Use a powered hub at the telescope mount connecting to your laptop, the remote into the laptop.
I use this model, which is powered by 5v, so I use a 12v->5v-3 amp regulator between my 12volt battery and the USB hub. That way, everything runs. off the same power circuit. I've always had good results with USB-Gear, but any powered USB hub will work.
