Hi, I try to make a new driver for infinity unlimited usb. I use the usbserial layer to manage the lowlevel functions like probing or ttyUSBx creation/selection. The driver works but only after a first sequence "open and close" of the device by a program in the user space. After this first "open/close" sequence, all is running well. I join the (hugly ?) code for a review. I'm a newbie in driver coding, so there is a lot of bad things in the code probably and with your help, I hope to have soon a clean and working code. For exemple, I'm not very sure if I need to use the lock mechanism (spin_lock_irq) . This code is for kernel 2.6.21 with GCC 4.1.
Thanks, Alain
