2 USB scanners in XP, need workaround
hi all,
understood that XP doesn't suppot 2 USB scanners, unfortunately too late for me since I have already purchased the 2nd one and will need both, one for dedicated scanning and one for casual scanning and printing (all-in-one). I can currently plug and unplug the device and reboot to switch devices, does anyone have a workaround so that at least I don't have to reboot? I guess I can deal with the plug/unplug, but having to reboot every time is crazy. thanks david |

Not sure what your problem is. I have 2 usb scanners connected all the time
and have not had a single problem!! Perhaps you have a driver problem.

I guess I can deal with the plug/unplug, but having to reboot every time is crazy. I don't know why you need to reboot. Are you unplugging correctly or just unplugging? On the bottom right of your taskbar there should be an icon for connected devices. You need to double click it, select the device you want to stop, stop it, then unplug the device. When you plug a new device in, it will automatically recognize the device. As someone else asked, why can't you have them both on line at the same time? Do you have a shortage of available USB ports? I know some scanner vendors say you can not connect through a USB hub, but for well under US$50 you can add a brand name card for additional USB ports. Many local stores carry 4 and 6 port add-on cards in that price range. Since these use a PCI slot on the mainboard, they are not recognized as hubs, but are considered native ports by any hardware. |

Dear both,
this is the error that I have and the microsoft documentation about it.... http://support.microsoft.com/default...b;en-us;324756 both my scanners are USB, I have enough usb port, just that they don't work at the same time, because they are competing for the same usbscan.sys file. I tried unplugging and plugging but didn't work and have to reboot. any other ideas? I am interested in DavidG's set up, would you share a little more, on the model of the scanners, OS, etc.? are you using both as USB or through SCSI? thanks. david "Major Malfunction" wrote in message . net...

"Randy Lane" wrote in message om... For all of you but David, The error is only for Windows XP. In XP, the USBSCAN.SYS driver will only allow one device at a time to be connected. There are no "setups" that will allow to do anything different than unplugging one and plugging in the other. And Microsoft to this day has never given a hint whether they will fix this. I followed you link to Microsoft about the problem. Very interesting, especially since the XP Resource kit makes no mention of this issue. Have you tried stopping the device prior to unplugging it? This won't change being able to use only one at a time, but it should prevent the need to reboot. BTW, MS gives the following link for USB Resources: http://www.microsoft.com/windows/resekits/webresources Maybe there is something there to help you. |

Hi David,
One is an Epson Perfection 1250, USB 1. The other one is a HP Scanjet 5550C, USB2. Both are connected directly to ports on the PC. OS is Win XP Pro. They are both permanently connected and can be used as required without any re-booting. Perhaps the reason both of mine work is that the HP is USB2???? Have never had any problems with either. Hope you get to the bottom of the problem. Dave "david" wrote in message om...

Dear all,
just want to post the latest findings so others can reference. I have an Epson 3170 and a Lexmark X83 all in one. What I have done is downloaded the latest firmware and driver for the lexmark and the Epson. After that, turning the device off will get it to release the driver in memory. So the 2 devices are connected at all time, I just have to turn them on and off, depending on which one I need to use. And this can avoid having to reboot. while not the best solution, I am much happier with it. Thanks all for your input. david "DaveG" wrote in message ...

I think the all-in-one is what creates the special problem they are seeing. |
