From: Gene Hall on 23 Jan 2006 12:48 I have a Symbol Barcode scanner that I use with the serial port. I wrote some simple VB code using MSCOMM to read the input from the scanner. Works fine but now I need to do the same thing using a USB port. My ASSumption is that I will need to work with the USB drivers but wondered if any of you VB gurus have done this. Thanks so much Good group here. Gene

Windows NT and Windows 2000: http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=33181&lngWId=1 You may wish to look at: http://www.vbcodesource.com/downloads/usbModulesFromIntel.zip > Thanks so much > Good group here. > > Gene

Many of the USB scanners I've used do *not* require any USB programming. Some emulate keyboard input, i.e., the barcode characters are "typed" into your application, while others create a "virtual COM port" which is just another serial port. If the latter is the case with you scanner, you may not need to change anything except the COM port number. Regards, Eric Schuyler
From: Gene Hall on 23 Jan 2006 19:46 Thanks desertphile, I'll check the links out. Eric: A virtual comm port? I like that. I'll look into it and reply back to the group on what I find. I'll also supply the code if it turns out Symbol barcode scanners do this. Thanks very much. <eschuylerTAKE(a)THISadelphiaOUT.net> wrote in message news:neidnRUGtMb8skjeRVn-vg(a)adelphia.com... > "Gene Hall" <ghall(a)austin.rr.com> wrote: > > > >I have a Symbol Barcode scanner that I use with the serial port.
