I've got a Net-A-USB114 1.1 self powered 4 port hub that is schizoid! The only way I can get it to work at all is to plug it in right after a clean startup, not a restart. It will work just fine until I power the 'puter down. When I boot back up, no hub is recognized. I have tried everything but pouring booze in the darn thing but nothing works. Any ideas?
