These were bought at different times with two different for suppliersĭoes anyone have an idea what could be wrong and how to fix it? ?!īought more than 40 computers that I have this problem. I googled after a response after my problem, but it seems I'm the only one who experience this issue. In this case, it takes about 2 seconds for the code scanner barcode to mount correctly in windows under the heading "devices and printers" and then works perfectly, even after a reboot. And leave the USB - hub to take care of the communication with the Barcode Scanner. I found a workaround by connection of bar codes in a USB hub, and then plug the USB hub to the computer. Tried newly bought barcode scanners and "used" barcode scanners earlier who works on other computers, but the problem remains. I tried to update all the drivers available on the website and same (chipset drivers) but nothing has helped to solve this problem I suspect that there is a compatibility problem between barcode scanner and card USB controller on the computers. It works fine until you restart the computer.Īfter restart the computer cannot detect the scanner Barcode correctly without re - appears as unknown device. Sometimes when you move the USB back can I sometimes the scanner at hand to be recognized as an HID device or a Datalogic barcode scanner,
When you connect the scanner to a USB port, Windows will try to install this as a HID, but it takes an unusually long time, about 7-8 seconds, to boot the device and install the drivers and appears as an unknown device in windows "devices and printers" and the hand scanner does not work.
The brand and model of the bar code scanner is: I need assistance with our Barcode Scanners that doesn't work on our newly purchased computers at HP with Windows7 Pro x 64 operating systems. "Unknown device" USB Barcode scanner, problem with the USB controller driver?
