The mouse is set to /dev/wsmouse1

When I try to use usbhidctl over it, it says the device is busy
under X. If I quit X and try to loop that command using -l it
does not loop. It says :

[root][4] usbhidctl -f /dev/wsmouse1 -l -a
usbhidctl: USB_GET_REPORT_DESC

Whatever the command, it always reports the same string.

I tried -a -v, -l -a, -a -a -v

:/

Polling the internal mouse reports the same thing (the laptop has a
trackball set to /dev/wsmouse0 but X is configured for /dev/wsmouse1 only).
