Hi All,
I have some clarifications on usbserial driver are as follows First one is on usbserial module count usage. When I'm disconnecting a device and module count is not reduced, when we remove the device, driver invokes disconnect function and unlink all URB related transactions other than decrementing the module count. Please tell us how to decrement the module count after disconnecting the device. My Second clarification and my observation on close function After connecting a USB device to the system, open Kermit application and give check for power status and give AT+CFUN=0 command, after execution of this command device disconnects and connects it back to the system. If we close Kermit application after above steps, it closes the application and calls destroy serial function to unlink URB's. Again if we try to open the device, it does not open, since its already closed and unlinked URB requests, until we again disconnect and connect it back we can not open the device. Please tell me the significance of calling destroy serial function in close function and how to avoid this problem.
