hello, A while ago I posted a patch which added SIGIO to the allowed signals for urb completion (in addition to the RT signals). I did this because it allows me to do asynchronous urb completion in the user-mode linux hcd. Can this be included in the kernel or are there any problems? At the moment the uml hcd simulates interrupt requests with bulk request. My understanding from usb says this requires much more bandwidth. It would be far more efficient (not to mention cleaner) when this could be avoided. A while ago a patch was submitted to add interrupt support to usbdevfs. Are there any problems with this patch or can this be included too? thank you, J. _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: http://lists.sourceforge.net/lists/listinfo/linux-usb-devel
