General Comments
You will most likely need kernel version 2.6.20 or higher
Ubuntu Feisty 7.0.4
To prepare your environment run the following:
sudo apt-get install linux-kernel-source linux-kernel-headers
Uncompress /usr/src/linux-source-2.6.##.tar.gz
cd /usr/src/ sudo tar -xvf /usr/src/linux-source-2.6.##.tar.gz
link it to /usr/src/linux
sudo ln -s /usr/src/linux-source-2.6.## /usr/src/linux
ensure /lib/modules/`uname -r`/build exists,
ls /lib/modules/`uname -r`/build
then run the following:
mkdir usb_module_dir cd usb_module_dir cp -r /usr/src/linux/drivers/usb/* . cd gadget echo "KDIR := /lib/modules/`uname -r`/build" >> Makefile echo "PWD := `pwd`" >> Makefile echo "obj-m := dummy_hcd.o gadgetfs.o" >> Makefile echo "default: " >> Makefile echo -e "\t\$(MAKE) -C \$(KDIR) SUBDIRS=\$(PWD) modules" >> Makefile make
Once the kernel modules ( dummy_hcd.ko and gadgetfs.ko ) are built, you must remove (or move) the gadgetfs and net2280 as follows:
sudo mv /lib/modules/`uname -r`/kernel/drivers/usb/gadget/net2280.ko ./original_net2280.ko sudo mv /lib/modules/`uname -r`/kernel/drivers/usb/gadget/gadget.ko ./original_gadgetfs.ko
and replace them with the new modules:
sudo cp dummy_hcd.ko /lib/modules/`uname -r`/kernel/drivers/usb/gadget/ sudo cp gadgetfs.ko /lib/modules/`uname -r`/kernel/drivers/usb/gadget/ sudo depmod
The net2280 module provides conflicting symbols and causes interference with the dummy_hcd module.
