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 ehci-pci [27161.996037] usb 1-5: device descriptor read/64, error -32 [27162.420048] usb 4-1: new full-speed USB device number 2 using uhci_hcd [27162.563098] usb 4-1: not running at top speed; connect to a high speed hub [27162.601106] usb 4-1: New USB device found, idVendor=1d6b, idProduct=0106 [27162.601112] usb 4-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [27162.601115] usb 4-1: Product: Multi Gadget [27162.601118] usb 4-1: Manufacturer: foo [27162.601121] usb 4-1: SerialNumber: 123456789 [27162.614766] cdc_ether 4-1:1.0 usb0: register 'cdc_ether' at usb-0000:00:1d.2-1, CDC Ethernet Device, c6:8b:83:74:f2:f3 [27163.195272] cdc_ether 4-1:1.0 usb0: kevent 12 may have been dropped
Stop seemed to work, too:

Display off, on wifi:

..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.
