It's good practice to pull up data/clock lines with some resistors of 10k or so. Especially when connecting to newer motherboards. In some cases signal has levels between 1.5 and 2.5 volts, and mouse don't work. Pulling up helps in that situations and doesn't harm if unnecessary.

si n o funciona es por que el mouse no es compatible

exacto, en esta página esta una descripción del diagrama del adaptador que los ratones que el microprocesador puede manejar ambos protocolos utilizan, TODOS los otros ratones o son PS/2 o son USB generalmente los ratones no tienen micros duales.
