I am using a Overo Gumstix board on top of a tobi base board running Angstrom linux. I would like the USB OTG port to be configured as a USB serial device such that it appears as a USB CDC ACM when connected to a Linux box.
When I run
modprobe g_serial use_acm=1
I get "error inserting g_serial no such device"
g_serial.ko is on the system so this kernel module should be loaded.
When I run dmesg, I see a MUSB HDRC and also a EHCI device but nothing about serial devices.
When I look at the OMAP_3530 processor spec it shows an OTG controller module.
Has anyone done this before? What am I missing?
Any thoughts on how to proceed ?
