extra USB ports on Rpi - using USB hub

[renerene]

I have more then 4 devices so I've added a simple USB hub (Action) to my pi. In different Domoticz sessions all devices have worked, so I guess the hub is Ok. Problem is that after reboot some devices don't show up.

Can somebody give me a hand on how to use this tutorial in conjuction with a hub?

Before using the hub:
command: sudo nano /etc/udev/rules.d/99-usb-serial.rules

Code: Select all

SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="A198D23", SYMLINK+="ttyUSB-RFXCOM"
SUBSYSTEM=="tty", ATTRS{idVendor}=="0658", ATTRS{idProduct}=="0200", SYMLINK+="ttyUSB-OPENZWAVE"
SUBSYSTEM=="tty", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", SYMLINK+="ttyUSB-RFLINK" 
SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="P117QJ2I", SYMLINK+="ttyUSB-Pkabel"

After using the hub:
command: lsusb

Code: Select all

command: dmesg | grep ttyUSB

Code: Select all

[   11.786335] usb 1-1.2: FTDI USB Serial Device converter now attached to ttyUSB0

command: udevadm info --name=/dev/ttyUSB0 --attribute-walk

Code: Select all

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

It's probably a power issue.
Try an externally powered hub
