I am currently communicating between my Beaglebone and a Maple board via a serial connection directly through a USB cable. This works well. (LeafLabs Maple is an Arduino-like board with an on-board USB connector)
Due to power requirements I want to relpace the direct USB connection with a power supplied USB hub but when connecting the Maple board this way I do no longer see the serial device listed. I am new to Linux/Debian and am unsure what to do from here, and if it's even possible to perform serial communication through an USB hub. ----------------------------------------------------------------------------------------------------- Direct USB(Beaglebone)-to-USB(Maple) serial communication (works) ----------------------------------------------------------------------------------------------------- Beaglebone terminal: # uname -a Linux beaglebone 3.8.13-bone47 #1 SMP Fri Apr 11 01:36:09 UTC 2014 armv7l GNU/Linux # lsusb *Bus 001 Device 003: ID 1eaf:0004* Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub # ls /dev/ttyA* */dev/ttyACM0* -------------------------------------------------------------------------------------------- Serial communication through USB hub (missing serial device?) -------------------------------------------------------------------------------------------- Beaglebone terminal: # lsusb *Bus 001 Device 002: ID 05e3:0612 Genesys Logic, Inc. *<- this only shows up when using a special hd-USB cable.
