Identified mid-rapidity particle spectra of $\\pi^{\\pm}$, $K^{\\pm}$, and $p(\\bar{p})$ from 200 GeV p+p and d+Au collisions are reported. A time-of-flight detector based on multi-gap resistive plate chamber technology is used for particle identification. The particle-species dependence of the Cronin effect is observed to be significantly smaller than that at lower energies. The ratio of the nuclear modification factor ($R_{dAu}$) between protons $(p+\\bar{p})$ and charged hadrons ($h$) in the transverse momentum range $1.2&lt;{p_{T}}&lt;3.0$ GeV/c is measured to be $1.19\\pm0.05$(stat)$\\pm0.03$(syst) in minimum-bias collisions and shows little centrality dependence. The yield ratio of $(p+\\bar{p})/h$ in minimum-bias d+Au collisions is found to be a factor of 2 lower than that in Au+Au collisions, indicating that the Cronin effect alone is not enough to account for the relative baryon enhancement observed in heavy ion collisions at RHIC.
