John, I just re-tested the config options from comment #5 on the latest linux-linaro-2.6.38. I think the options are working, but the USB code seems a little buggy.
Basically I can get the g_serial module to work. However, you do get a flood a dmesg errors. The same messages occur when trying g_storage_file, and in that case I can't perform a mount from the host system to the device. The message I'm getting flooded with is: musb-hdrc musb-hdrc: configured as A device timeout It looks like its coming from: drivers/usb/musb/omap2430.c I apologize for not trying this against your tree. -- You received this bug notification because you are a member of Linaro Release Team, which is a direct subscriber. https://bugs.launchpad.net/bugs/730698 Title: musb config'd out on 2.6.38-1000 kernel Status in Linaro Linux: Invalid Status in “linux-linaro-omap” package in Ubuntu: In Progress Bug description: I'm on a Beagle-C4 board with a powered usb hub plugged into the OTG port with a usb ethernet adapter. It looks like MUSB was disabled by commit 61e9beafdd6f2b2d27ad5935a2de9c46709b9671 and I think this is the reason I can't use the ethernet I have plugged into the OTG port. grep -i musb /boot/config-2.6.38-1000-linaro-omap # CONFIG_USB_MUSB_HDRC is not set At boot I don't see any hub lights on (except the power LED); on 2.6.37-1002 (and earlier) I used to be able to get the Hub to come on by doing a modprobe g_ether; my guess is that kicked the port into OTG host mode. That now says no such device when I modprobe g_ether. The other recommended trick of writing to /sys/devices/platform/musb_hdrc/mode doesn't help since that's missing.
