I am using version 4.8.4. Previously I was able to successfully import transactions in USAA Federal Savings bank but now unable to. When I try to setup online access, it says "no suitable accounts can be found". I am using Kmymoney OFX. Is anyone else having similar problems?

You're probably not alone with this, as we are: recent changes at USAA hit other applications as well. Here are some links to threads on the GnuCash mailing list you may want to read to get more information about the problem:

I am pretty sure that your KMyMoney version is too old to support that new stuff and I don't know if the newest version can cope with it.

More progress
