Tablet error: "DeviceUnauthorizedAccessException: Not permitted to open HID class device at /dev/hidraw7."

The tablet works fine outside of osu! and even works in osu! without tablet support on, but trying to turn the tablet support on gives this error: "DeviceUnauthorizedAccessException: Not permitted to open HID class device at /dev/hidraw7."

Since you said the tablet works outside of lazer: Are you using OpenTabletDriver or the (kernel module) Wacom driver? If OpenTabletDriver works with your system config, then I dont see a reason for it to not work embedded in lazer as well.

The kernel module was installed automatically, I haven't installed OpenTabletDriver separately. I solved the problem (see #24891 (comment))

Problem solved, the problem was caused by missing udev rules. I followed the instructions at https://opentabletdriver.net/Wiki/FAQ/Linux (Failed to open device streams)

• Installed dotnet 7 using instructions from https://learn.microsoft.com/en-us/dotnet/core/install/linux-debian

git clone https://github.com/OpenTabletDriver/OpenTabletDriver.git
cd ./OpenTabletDriver
./generate-rules.sh
sudo mv ./bin/99-opentabletdriver.rules /etc/udev/rules.d/99-opentabletdriver.rules

After doing the commands and rebooting, it works now.
