you can use USB hubs or USB extension cables with a built-in hub. By chaining up
to 5 hubs, you can achieve an effective cable length of up to 25 m (
∼
82 ft).
As USB cables become longer they are more sensitive to EMI,
because they make a longer antenna that can pick up more
noise. These issues can be mitigated by using higher quality
cables with better shielding. Thicker cables tend to be better than
thin ones, and braided shielding tends to be more reliable than
only foil. Furthermore, longer cables may introduce signal
degradation and timing issues that, if necessary, can be mitigated
using shorter cable segments combined with hubs that amplify
the signal and handle delays on a per-cable basis.

Power supply
The Kvaser Hybrid CAN/LIN is powered from the USB port. You also need to apply
a reference voltage to the LIN reference power pin when running the channel in LIN
mode. See Section 4.3, CAN/LIN connector, on Page 13 for pinout information.
