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.
