I have seen this constantly claimed, and never reasonably evidenced. It's also hard to believe the kind of American exceptionalism that supposedly causes these problems that everyone else can easily solve, despite an environment that is clearly heavily politically invested in solving it (because that also avoids the appearance of racism).
Meanwhile, American proponents of voter ID can readily find people including among the supposedly discriminated-against groups who will testify to the contrary.
In Canada a drivers license is enough to vote.
