Hey all,
first off, im completely done with my inmoov project! (coding-wise)
everything works, but i came across a lil blip while trying to fire him up:
im using a laptop that has only three usb ports, so i needed more for the arduinos and webcams, so i used a usb hub.
the problem is, when i use the usb hub, i get a sendMsg Input/Output Error in writeByte
I know its a problem with the usb hub because when i plug the arduinos directly, it works fine.
has this happened to anyone else? Can somebody try it with a differnt usb hub to see if its a brand specific problem or something?
USB Hub possible solution
I had this same problem. If I plugged in more than the 2 arduino's and the camera in the eye, I would get the same message. My USB Hub came with a power supply, If I use that everything runs OK.
Maybe try that.
alrighty will try
alrighty will try that
thanks for the tip!
LACK OF POWER IS THE ROOT OF

good luck JCInMoov ;)
Still doesnt work.... tried
Still doesnt work....
tried it with the power supply..
maybe its something wrong with the usb hub itself?
I use a IOGear USB hub on
I use a IOGear USB hub on more than one Arduino and it works ok. It still sounds like a power issue. Does the hub work with 1 Arduino? I assume you are powering the Arduinos from the USB hub, can you power them with the barrel jack on a wall wart?
