Measures to improve the reliability of the USB interface.
The switching of electrical consumers (laboratory power supplies, power supplies, motors, heating coils, neon glow) can lead to the disconnection of the USB port on your computer, especially if these consumers and the computer are connected to a common power strip.
In case of problems, the computer should have an isolating transformer or supplied through a dedicated circuit.
The reliability of the USB port of the personal computer or notebook computer can be improved by simple measures:
- Use a high-quality USB cable with ferrite core
- Number of USB devices used reduce because the total current is limited to 500mA,
- Use of an active (self-powered) USB hubs,
- Using notebook power supplies with ground.
In particular, the use of an active USB hub with its own power supply can improve the reliability.
