If these drivers are for specific USB devices it is straight forward to turn them into kernel based drivers. If we are going for plug and play this needs to happen. All USB device drivers can be implemented in user space, but that doesn't mean you want to do that. Putting device drivers in the kernel subjects them to code inspection, they get shipped everywhere, they autoload when the device is inserted, they participate in suspend/resume, etc. If these are generic USB serial devices being used to implement IR that's the hobbyist model and the driver should stay in user space and use event injection. If a ft232 has been used to build a USB IR receiver you should program a specific USB ID into it rather than leaving the generic one in. FTDI will assign you a specific USB ID out of their ID space for free, you don't need to pay to get one from the USB forum. Once you put a specific ID into the ft232 it will trigger the load of the correct in-kernel driver. > > Regards, > Maxim Levitsky > > -- Jon Smirl jonsmirl@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
