Has anyone had a problem with a USB drive constantly disappearing and not being recognized? My current solution is to delete drivers in device manager then wait until they load again. This is a temporary solution. I am using a VivoTab ME400C tablet pc with full win8 in a public environment as a kiosk and users are exporting data via the usb. I cannot ask people to constantly delete drivers before they try an export to a pen drive. Has anyone encountered this issue and if so, are there any better solutions? Thanks in advance.
