Having trouble when using a USB hub. #6

Closed bustavo closed 10 years ago

bustavo commented 10 years ago

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.
