Hi I was wondering whether any one had got any experience or software to access the USB ports. I have got a rs232 scanner that I can connect to a USB port. I would like to get it to work to read ISBN numbers so I can put the details in a mysql database. I have done programming before (java C shell scripts) but am quite new to ruby, what I have seen so far is really good. I would be very glade of some help/or software I can hack to do what I want to do with ruby as the language of choice. Adrian

They can run through USB, parallel or rs-232. I know that there is some VB code out there to test the OPOS interface, so it might be possible to find that, and convert it. Sorry I don't remember how they did it, but it wasn't too complex (c'mon, it was in VB) Matt
