Hello DIGImend team

There is an issue with page Huion WH1409:

The table is not usable.

My system

Linux Mint 20 with 4.8 kernel
Laptop Dell Latitude latest model.
The stylus is charged.
Tablet is on (sometimes I plug it on/off to test it)
Restarted system several times.
Tested with plain kernel alternatively with digimend/9 following steps.

the tablet is on and the sensitivity led is highlighting when i touch her with the stylus.

However the tablet is not responsive.

I tried David Revoy great tutorial which I used it with success in the past on a kernel like 4.15 and 4.18 or more but this time it doesn't work: https://www.davidrevoy.com/article331/setup-huion-giano-wh1409-tablet-on-linux-mint-18-1-ubuntu-16-04

WIth dongle on I cannot find the device in the list.

I stay at your disposal.

Thanks
