Can you provide the result of : lspci -v # to list your hardware (usb + hub) lsmod|grep -Ei "usb|hcd" # to list drivers that make it work cat /proc/interrupts cat /proc/pci (I asked for an eaglediag -sui which provides quite the same) This issue may depend on hardware and could be addressed by linux-usb ML. In an answer, http://forum.ubuntu-fr.org/viewtopic.php?pid=34700#p34700 the user infers that it may come from the plugged device being managed by - either uhci (when directly plugged to usb) - or ehci (when plugged to hub) (can be seen in /var/log/messages when the device is detected). Well, either an usb module problem or perhaps power-throughput not suficient ? the error given by eagle-usb being [EAGLE-USB] Unable to submit interrupt URB! @++ Ben'. aka baud123
