Hello, I was trying to make a driver for a touchscreen but was stuck in these problems: 1. I thought the serio subsystem is much like the parport subsystem, where the subsystem calls the driver's 'attach' function upon registeration of the driver, giving it a reference to each unclaimed parport device. But when i register a serio driver, the subsystem does'nt call the 'connect' function of my driver. 2. I could verify that my touchscreen is working on ttyS2 using 'cat /dev/ttyS2'. So i registered an interrupt handler on irq 4 in my driver. But that never gets called no mater what i do with the screen. I also tried all other irq's (though i was'nt allowed to register 2/3 of them). Anyone around with experience of serio subsystem who would like to help/guide me? -- Kernelnewbies: Help each other learn about the Linux kernel.
