May be I need hack libusb.c to match device number instead of port (use port
directive from config file, but specify device number instead of path to
device port), I found that udevinfo shows bus number and device number
(different for all devices).
Second variant is to place lock's on devices and do not match devices that
locked.

I can't do this, after reboot I found that all devices sits on second bus
instead of first...

lsusb -v shows iSerial parameter set to zero for all devices.
In attachements You can find output of udevinfo -a --name=/dev/usb/hiddev[1-3]
and lsusb -v

Udevinfo 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.
