That would be an A-Male to A-Female "extension" cable, such as Wouter's: USB-EXT (which seems to have the wrong photo, by the way!) and they are very handy, but A-Male to A-Male cables are out there too, see Wouter's: CABLE-USB-1-5-A-A I think the latter's the subject of the "Why?" :-) Cheers, Howard Winter St.Albans, England -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
