If you research this unit there's a lot of posts about the product. This is not a post about fixing it because the issue is there and the code/driver is not open source. So it is what it is. A cheap product with issues.
Sometimes it seems folk need to hear it again.
I recently installed a package for transferring my vhs video to digital format. The package is called Ez grabberand comes with a piece of hardware that allows me to capture a VHS analogue tape to Digital format. When I boot my HP Pavilion Slimline and open the software it launces but does not recognise the hardware. However, if I delete the driver from Sound, video and game controllers using Device manager, remove the USB cable from the grabber hardware and reboot. If I then insert the usb the machine re-loads the driver and the software works. Does anyone know why this happens and how I can ensure that the software works with hardware every time I boot up rather than going through the difficulty of uninstalling and re-installing the drivers?
