Hi, I've installed a Belkin 4 port USB card on my 8500/180 (System 9.1) and it works - sometimes. If I insert a flash drive, an external floppy drive or a hub one or the other may appear on the desktop (these are the only USB components I've tried so far). It doesn't seem to be reliably hot-swappable? If I hook the floppy drive up to my iMac, (w/Panther) through a Macally 4 port hub, it won't boot at all. I don't have the documentation or the power supply for the hub, it is marked 5 volt dc. I'm using the 5 volt power supply from a zip drive. So far, I haven't been able to isolate the specific variable. Any ideas as to what is occurring here? Is there something available like scsi probe or some other workaround to avoid having to re boot the computer with each change? Thanks, Bob _________________________________________________ For information concerning the MUGLO List just click on http://muglo.on.ca/Pages/joinus.html Our Archives can be viewed at //www.freelists.org/archives/muglo Don't forget to periodically check our web site at: http://muglo.on.ca/
