If the 3V3 and the 5V power supplies are used simultaneously, please observe that the
maximum power available from the USB bus is 2.5 W.
Multi master mode is not allowed on the I2C bus while the USB uEye LE camera is used.
From driver version 3.20, the I2C bus is operated with an effective clock frequency of
approx. 250 kHz. For earlier versions, the clock frequency is 100 kHz.
The digital input of the USB uEye LE is not potential-free and has no protective circuits.
Due to hardware limitations, the USB uEye LE can only be triggered on the falling edge.
