not working on Manjaro, kernel 5.10.30

[eduardosm]

I am trying to test the driver on Manjaro with kernel 5.10.30. I have successfully built the module and loaded the drm, drm_kms_helper and fl2000 modules. I have also added quirks=1D5C:2000:USB_QUIRK_NO_LPM to boot params. However, after plugging the dongle, nothing apparently happens.

lsusb lists the device as:

Bus 002 Device 008: ID 1d5c:2000 Fresco Logic FL2000/FL2000DX VGA/DVI/HDMI Adapter

/:  Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/8p, 10000M
    |__ Port 1: Dev 8, If 0, Class=, Driver=fl2000_usb, 5000M
    |__ Port 1: Dev 8, If 1, Class=, Driver=fl2000_usb, 5000M
    |__ Port 1: Dev 8, If 2, Class=, Driver=fl2000_usb, 5000M
    |__ Port 1: Dev 8, If 3, Class=Mass Storage, Driver=usb-storage, 5000M

And dmesg shows:
