Having trouble when using a USB hub.
Closed this issue · 1 comments
I have successfully ran decoding_carelink connecting the Carelink USB directly on the Beaglebone Black USB port.
Since I want to add Wifi connectivity to the device, I added a USB Hub where I am connecting the WIFI dongle & the Carelink.
I have successfully connected to WIFI ( proving that the hub is okay with the Beaglebone? ) but the Carelink seems to stop working.
I've tried on 2 different hubs with the same result but wanted to see if someone knew something about it before going looking for a different USB Hub.
Hub 1:
Steren 4 port mini USB HUB
Hub 2:
iConcepts 75053 USB HUB
I run:
dmesg | grep ttyUSB
./insert.sh
python decocare/stick.py /dev/ttyUSB0
I get the following output:

Update.
I went and bought a different USB hub and got it working! ( ATIVA 3 port hub )
http://www.officedepot.com/a/products/545553/Office-Depot-Brand-3-Port-USB/
I looked for one that had the least amount of ports / no LEDs / 5v - 500mA output
So it seems that not all USB hubs work correctly for the Beaglebone. I think it confirms my hypothesis that it has something to do with power output capabilities.
