My best customer bought a new Sony VAIO (XP home)desktop in which she uses legasey sewing software that needs a security device attached to LPT1. On her old Dell laptop (Win98) these worked fine. But after software install on the VAIO, the programs say security device not found and will not run. Is this an XP problem? I have tried changing the LPT1 in CMOS (epp/ecp, using a dma etc.) and reinstalling the port in device manager. No difference. Do I need to use Win 98 compatability mode for thesedevices? I’ve seen them used on other XP units fine. The port was tested with loopback and came back good.
