Using the USB port of an EVMK2H board

John Romein

I would like to use the USB port of an EVMK2H board (not the mini-USB client port that connects to a host PC, but the USB-A port next to the ethernet ports), to connect to an Arduino board.  Therefore, I need to load the cdc-adm.ko kernel module, but this one is not ditstributed with the linux kernel that runs on the ARM cores.  I tried to build one from a stock linux 3.10.10 kernel (with "ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make modules"), but that one causes kernel panics as soon as I load the module.

How can I compile the cdc_acm driver?  I am using mcsdk 3.00.04.17 which contains a (patched) linux 3.10.10 kernel.

Thanks in Advance,  John

BTW, it would also be acceptable to use an FTDI USB->serial driver, but this driver is also not included in the distribution.
