I've been working on my kernel module and everything have been coming along nicely. There is one issue with my device. If I send two urbs to the device without enough wait between the calls then the device doesn't respond with status messages anymore. Is there a kernel mechinism available to handle this sort of issue? Note, I cannot always predict two sequential calls. For example, the user may ioctl() two times without enough delay.
What would be ideal to to place all these requests on a queue where they will be executed in order with no less then TIME_INTERVAL between calls. It would be great if identical requests could be collapsed into one. I am new to kernel hacking so I don't know if I should be looking into waitqueues, workqueues, if I need to make my own data structure, or if there is a better way around this problem.
