There are different versions of the prolific chipset and unfortunately they changed the init sequence of version 3.00 and up without changing the device ID (If you're interested for more check the archives (current) arround January 21st). 5.4 has the new uplcom driver which checks the revision maybe you can apply the cvs version to your 5.3 (guess). -Harry > > Does it have to do with the difference of callin and callout > devices?
