On one FT4232 chip is 4 uart interfaces. Two first uart can be configured as I2C, SPI, JTAG, etc. I can unbind only full usb device not single interfaces on devices. When I try unbind interface I get "write error: No such device" > How do you pass that particular interface to your i2c / SPI? For example: In similar kernel module to ftdi_sio I can select only other interfaces. Configuration of FT4232 is per interfaces, so there should be no conflict. Method of elimination some interfaces by return ENODEV is used in this driver for dedicated JTAG port in some devices - see ftdi_jtag_probe() and ftdi_stmclite_probe() function. This patch allows use this same solution for user defined hardware. > > Signed-off-by: Robert Ryszard Paciorek <r.pacio...@icm.edu.pl> > > Sebastian Regards, Robert -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
