It doesn't cause errors on even a 100M network card, it just can't use all the available network bandwidth (though the data it gets is still noticably faster than with a 10M). I suspect the timing requirements for USB are not meetable. _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx ************************************************************** http://libretto.basiclink.com - Libretto mailing list http://www.silverace.com/libretto/ - Archives -------TO UNSUBSCRIBE------- Reply to any of the list messages.
