Ah. Is this device a 1.1 device behind a 2.0 hub? Or a real 2.0 device? A 1.1 device with a UHCI or OHCI driver? > For this reason I am suggesting a usb_intr_msg() function which is > written as usb_bulk_msg() but with usb_fill_int_urb() instead of > usb_fill_bulk_urb(). Take a look at how usb_fill_int_urb() and usb_fill_bulk_urb() are defined, they are just simple "fill up the structure" functions, and are not different. > Regardless, I have grown fond of my completion variable solution since > it will keep me from having to use kthreads to achieve some of my > goals. That's fine. I'm still interested in finding out why usb_bulk_msg() is failing for you, if you don't mind my questioning :) thanks, greg k-h ------------------------------------------------------- Using Tomcat but need to do more?
