- set permissions on /dev/bus/usb/XXX as well - that's what new
  libusb uses by default

It seems that hal/udev set permissions for gcecchi into the wrong directory....
I'm not sure if the current udev rule is this line inside
/etc/udev/rules.d/50-udev.rules

ACTION=="add", SUBSYSTEM=="usb_device", PROGRAM="/bin/sh -c 'K=%k;
K=$${K#usbdev}; printf bus/usb/%%03i/%%03i $${K%%%%.*} $${K#*.}'",
NAME="%c"
