From: sukumar on 26 May 2008 01:16 I am new to the driver world...can any one give idea that leads to solve my problem .........if the device is connected to USB port of PC and the driver is not loaded for it we will get the message as driver has to be installed for that particular devce...in our reqiurement it should n't be like that and communication has too be maintained throgh another port either rs232 or any else i mean the device which doesn't has installed driver it has to use the driver of another port..can any one tell me how to implement this and any other ideas to develop virtual drivers
From: Don Burn on 26 May 2008 08:12 How can you tell what "port" you are on? It sounds like you are saying talk on USB if not, then try something else. If you can say what your model is such as: We have a unique USB device, if present we use it for communication if not we have a pre-configured fallback device to communicate. If it is something like that then a design can be discussed, right now you don't have a design, just some wishes. -- Don Burn (MVP, Windows DDK) Windows 2k/XP/2k3 Filesystem and Driver Consulting Website: http://www.windrvr.com Blog: http://msmvps.com/blogs/WinDrvr Remove StopSpam to reply "sukumar" <sukumar(a)discussions.microsoft.com> wrote in message news:4DD7A003-B3BA-4BDF-87CF-ED26B04410B3(a)microsoft.com... >I am new to the driver world...can any one give idea that leads to solve my > problem > > ........if the device is connected to USB port of PC and the driver is not > loaded for it we will get the message as driver has to be installed for > that > particular devce...in our reqiurement it should n't be like that and > communication has too be maintained throgh another port either rs232 or > any > else > i mean the device which doesn't has installed > driver > it has to use the driver of another port..can any one tell me how to > implement this and any other ideas to develop virtual drivers

From: David Craig on 27 May 2008 02:01 I realize serial is obsolete, but it still works. There are very useful USB to serial adapters that work well and the driver is stable. They are also very inexpensive as I have seen them for about $10 in Fry's. If your design only needs speeds that serial can handle easily, why go to all the trouble? P.S. Bottom posting is a real pain and if I hadn't been bored, I would have skipped your message.
