Hi, I am writing a USB device driver on the host side for sending and receiving messages to and from a specific device. I am using the USB skeleton template in the kernel source code (2.6.16.16)(/drivers/usb/usb_skeleton.c). I filled in the vendor ID and product ID values to fit my device and I can use the device driver for sending and receiving messages from user space (using the system calls open, read, write, close). Now I want to change the usb_skeleton.c to use interrupt endpoints instead of the bulk endpoints used in usb_skeleton.c. I just changed all the "bulk" to "int", but I get errors from the probe function, telling that it "Could not find both int-in and int-out endpoints". What do I have to do to make it work? Do I have to create a new setting for the interface? How do I do that? I want to understand the whole picture- it seems like the default for my device would be to use bulk endpoints. How was this decided? For instance- a mouse should use interrupt endpoints and this seem to be "hardwired" in the mouse. Would it be possible to change the settings to make the mouse send bulk transfers, and how would I do it in that case? Thanks in advance. / mogr -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
