Error 0? That sounds bogus. Perhaps this patch will take care of everything: http://marc.info/?l=linux-usb-devel&m=118531582013355&w=2 It has already been submitted to Greg KH, but if it takes care of your problem you might want to merge it immediately. It fixes an obvious bug that was recently introduced. Alan Stern ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
