I'm trying to use two usb serial devices with my yun. Both usb devices (a gps serial device and a rgb led) have been tested to work individually.
When I plug in the splitter, to start, my blink(1) mk2 (http://blink1.thingm.com) starts flashing in red, green, blue, white, repetitively. I think this means the device is only connected to power, I believe this because when I plug it into the usb port proper it doesn't do this. Regardless, once plugged into the splitter, when I try to control the light it tells me there are no blink(1) devices connected.
Same goes for the gps device, can't read from it.
Are there any packages I need to download to get multiple usb devices working through a splitter with the Yun?
