I tested with rmmoding two, and then modified kernel to do equivalent
operations.

Let me try again:

phy_module=phy_twl4030_usb
udc_glue=omap2430
udc_module=musb_hdrc

Ok, I did "start" with your script. After some fiddling it seems to
work, and PC detected the values:

[25379.533127] usb 1-5: USB disconnect, device number 12
[27161.884132] usb 1-5: new high-speed USB device number 13 using

[27163.195272] cdc_ether 4-1:1.0 usb0: kevent 12 may have been dropped

Stop seemed to work, too:

..so I believe gadget bits are still set.

I'm booting directly from NOLO over usb. Machine is running X, but
they are not active -- chvt. Screen is off.
