 Usage notes
 -----------
 
 The devices communicate via HID reports. The driver is loaded automatically by
 the kernel and supports hotswapping.
 
+Configuring fan curves is available on the D5 Next, Quadro and Octo. Possible
+pwm_enable values are:
+
+====== ==========================================================
+0      Set fan to 100%
+1      Direct PWM mode (applies value in corresponding PWM entry)
+2      PID control mode
+3      Fan curve mode
+[4-11] Follow fan[1-8], if available and device supports
