Hello,

all I can do is to write at linux-input@vger.kernel.org : https://lore.kernel.org/linux-input/24eaed9105633d03eded13e11c5a994bd93a81aa.camel@aegee.org/ (local) .

Writing a report in the Austing Group Mantis BT, requires an answer from the chair, that an account is created.

According to Andreas Schwab, it's a bug in the device driver

Hello,

please amend the errors at https://man7.org/linux/man-pages/man3/tcgetattr.3p.html that the function tcgetattr() can set errno to EINVAL 22 Invalid argument for /dev/hidraw files.

You should file a bug to the Austin Group, which is the group
responsible for the POSIX standard.

According to Andreas Schwab, it's a bug in the device driver.

Thanks,
Florian
