Why are you using ASIO4ALL? Since you say your Tascam 2x2 device has its own drivers, that should be all you need. You should not use ASIO4ALL if the regular vendor driver works.

If you have to use ASIO (with some exceptions) only supports one device at a time, so that would be normal.

Try the MME driver in BIAB and RealBand. It should work, and this will rule out BIAB or RealBand from the problem.
