Error recognizing devices on all usb ports

[anthoon]

Hello,
I have the HomeTroller SEL. I am using two Aeon labs Z-wave sticks (one for EU and one for US freq.) plugged into two of the three usb ports on my HomeTroller SEL. They work very well on dev/tty/USB0 and dev/tty/USB1, until i plug in the RFXcom receiver into the third USB port and activate it on dev/tty/USB2. Then my Z-wave EU crashes and the computer is no longer able to recognize and initialize it. If i restart with the RFXcom plugged in i get the same error. Once i de-activate RFXcom the z-wave stick returns to normal functionality.

Any thoughts on this?

Thanks
Anthony

Just sort of wondering if perhaps it's a power issue? I.e., maybe try using a powered USB hub and see what happens?
