missing USB ID 04d9:b534 in Blacklist

ModemManager is missing the Device-ID 04d9:b534 as a blacklist-Item.

On my System (Fedora 32) it uses /dev/ttyACM0.

Kernel detects it as:

[ 3530.187178] usb 1-1: new full-speed USB device number 11 using xhci_hcd
[ 3530.326148] usb 1-1: New USB device found, idVendor=04d9, idProduct=b534, bcdDevice= 1.10
[ 3530.326156] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 3530.326161] usb 1-1: Product: USB TO UART BRIDGE
[ 3530.326166] usb 1-1: Manufacturer: HOLTEK
[ 3530.326169] usb 1-1: SerialNumber: 0000
[ 3530.329314] cdc_acm 1-1:1.0: ttyACM0: USB ACM device

The connected device is a chinese clone of an Arduino nano with a LGT8F328P MCU.

ModemManager-1.12.8-1.fc32.x86_64 tries to communicate with the MCU and blocks the Device for the Programming Software (Arduino).
