udev rules execution problem after update since a few weeks [SOLVED]

For my external USB-to-serial-devices I have a ruleset that worked for years:

cat /etc/udev/rules.d/99-adapter.rules 
KERNEL=="ttyUSB*", SUBSYSTEMS=="usb", ENV{ID_VENDOR_ID}=="0557", ENV{ID_MODEL_ID}=="2008", SYMLINK+="ttyPL2303%n"
KERNEL=="ttyUSB*", SUBSYSTEMS=="usb", ENV{ID_VENDOR_ID}=="0403", ENV{ID_MODEL_ID}=="6001", SYMLINK+="ttyFT232%n"
KERNEL=="ttyUSB*", SUBSYSTEMS=="usb", ENV{ID_VENDOR_ID}=="067b", ENV{ID_MODEL_ID}=="2303", SYMLINK+="ttyPL2303%n"
KERNEL=="ttyUSB*", SUBSYSTEMS=="usb", ENV{ID_VENDOR_ID}=="0403", ENV{ID_MODEL_ID}=="6010", SYMLINK+="ttyFT2232%n"
KERNEL=="ttyUSB*", SUBSYSTEMS=="usb", ENV{ID_VENDOR_ID}=="0403", ENV{ID_MODEL_ID}=="6015", ATTRS{serial}=="DA00FBIE", SYMLINK+="ttyFT_VNA%n"
KERNEL=="ttyUSB*", SUBSYSTEMS=="usb", ENV{ID_VENDOR_ID}=="0403", ENV{ID_MODEL_ID}=="6015", ATTRS{product}=="UMFT234XD", SYMLINK+="ttyFT234%n"

Since a few weeks (probably because arch update) the additional symlinks do not appear any more. Testing the attached devices with command seems all right (in this case for line 5 from above).

udevadm info -a -n /dev/ttyUSB1 | egrep -e "KERNEL|SUBSYSTEM|0403|6015|serial"
    KERNEL=="ttyUSB1"
    SUBSYSTEM=="tty"
    KERNELS=="ttyUSB1"

    ATTRS{idVendor}=="0403"
    ATTRS{serial}=="DA00FBIE"
    KERNELS=="4-1.5.4"
    SUBSYSTEMS=="usb"
    KERNELS=="4-1.5"

    KERNELS=="pci0000:00"
    SUBSYSTEMS==""

Any Ideas? Is the syntax of my ruleset outdated and should be rewritten?

Re: udev rules execution problem after update since a few weeks [SOLVED]

It seems that ID_VENDOR_ID=0x8086 and ID_MODEL_ID=0x1c26 from your device do not match any entry of your rule, maybe you meant

KERNEL=="ttyUSB*", SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6015", ATTRS{serial}=="DA00FBIE", SYMLINK+="ttyFT_VNA%n"

?

Re: udev rules execution problem after update since a few weeks [SOLVED]

Thanks. You're right. After changing ENV{ID_VENDOR_ID} and ENV{ID_MODEL_ID} to ATTRS{idVendor} resp. ATTRS{idProduct} the devices are back again. Thanks again.
