Hi, We have a product where we connect a monitoring device to a Raspberry Pi via USB. The device uses serial commands to pass data back and forth and uses an FTDI chip with custom VID and PID to do this. We've used a custom `udev` rule on the Pi to pass the correct VID and PID to the driver (as per the instructions in the "FTDI Technical Note 101" and the ftdi-sio webpage) and this worked previously on the Raspberry Pi Model B (raspbian with kernel 3.10.25+) but today I've tried it on a Raspberry Pi A+ (raspbian with kernel 3.18.11+) but get errors in `dmesg` from the `udev` rule and the device is not recognized. --8<---- # dmesg | grep ftdi ftdi_sio: unknown parameter 'product' ignored ftdi_sio: unknown parameter 'vendor' ignored usbcore: registered new interface driver ftdi_sio ---->8-- Working driver version is "srcversion: 118C2FFAFBDC88DB1344F66" whilst I get errors with "srcversion: B86D6B2E065168765812137". Am I missing something here? Have the parameter names changed perhaps?
