SearchI had to "sudo chmod 666 /proc/bus/usb/001/021".
There is an opensource library (libftdi) from intra2net that lacks support of reading the dongleid.
After usb sniffing (LD_PRELOAD=/usr/lib/libusbsniff.so ~/ftdi/id/ChipID) and disassembling (ddd) parts of libftchipid (bitshift) i made a patch for libftdi.

Because udev didn't know anything of idVendor or idProduct if you remove a device i use ENV{PRODUCT} to match for my unplugged device:
ACTION=="add", KERNEL=="event*", SUBSYSTEM=="input", \
SYSFS{idVendor}=="1234", SYSFS{idProduct}=="5678", \
SYMLINK+="input/myevent"
