Hi Hans,
the extra definition will not work if I2C_ALGO_USB isn't known by your kernel
at all.
In i2c_algo_usb.c you will find this struct:
static struct i2c_algorithm i2c_usb_algo = {
.owner = THIS_MODULE,
.name = "USB algorithm",
.id = I2C_ALGO_USB,
.master_xfer = usb_xfer,
.smbus_xfer = NULL,
.slave_send = NULL,
.slave_recv = NULL,
.algo_control = algo_control,
.functionality = usb_func,
};
For your kernel you should use the old id we shared with a different driver:
.id = I2C_ALGO_BIT
Guten Rutsch
Joerg
