Kconfig says: config PPC_EP88XC bool "Embedded Planet EP88xC (a.k.a. CWH-PPC-885XN-VE)" select CPM1 help This enables support for the Embedded Planet EP88xC board. This board is also resold by Freescale as the QUICCStart MPC885 Evaluation System and/or the CWH-PPC-885XN-VE. MPC885 has an USB controller, but I was not aware Linux had any USB driver for the 885. Need to dig into history. Was initialy added by commit 3948f0e0c999 ("usb: add Freescale QE/CPM USB peripheral controller driver"), it explicitely says it should work on CPM. Christophe
