I have installed an Agfa SnapScan 1212P on A Compaq Deskpro En 400Mhz PC with 64Mb RAM along with all the latest software, however whenever I try to scan anything I receive the message "Please connect or switch on your scanner". I am also having similar problems with an Aries Scanner and a Deskpro EP (PII 350 196Mb RAM); I don't know whether this could be related. Both machines exhibit this problem with nothing running but Windows 98 and Sophos Sweep (Anti Virus Software) running. I have tried the obvious, checked cables etc but this doesn't seem to help. Any Ideas?
