Hello, 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 ? --Gregg |
