Just wanted to leave some feedback to possibly help others who encounter this error 
message that "NTMAPHLP is missing" when you try to use a Flash Drive. After recently 
having to reinstall my operating system, my ACP-EP Flash Drive no longer worked and 
I got this message that this above file is missing. 

The solution is that you must install the driver on windows 98SE for a USB 2.0 Flash 
drive to work. This is not necessary if you are using a more recent operating system 
but is required for Windows 98SE. Now that raises the question, which driver to use? 
You can install a generic driver from this below website that will enable you to 
use a USB storage device on any Windows 98SE operating system.

http://www.technical-assistance.co.uk/kb/win98se-usb-mass-storage-drivers.php

The actual application will be called:       nusb33e.exe

Click on the link within this page with the type:

Windows 98 SE Generic USB Mass Storage Device Drivers v3.3 - nusb33e.exe


Also to note, after installing the driver from this file and doing a restart, I had 
to remove the device from the device manager in My Computer and do another restart 
for the software to load and then my flashdrive appeared in my computer icon. 

Hope this helps.

I've never got these drivers to work for me. I always use the default drivers that come with the flash drive or can be downloaded from the manufactures web site. I've had this discussion with gewg may times as I'm sure he will comment.

(Though Linux has the best out-of-the-box hardware support of **any** OS, checking compatibility there is advised there as well.) A modern OS (e.g. FREE Linux) will have an approved hardware list. In addition, as the OP mentioned, a modern OS doesn't have this (USB) hoop to jump through. Since the OP stated that Maximus Decim's driver worked for him and Keith didn't provide the names of the brands on which these WON'T work, Keith's post is just noise (as is quite common for him).

I could not download the driver for my device because the back packaging had three possible drivers for my flashdrive to select from and yet not one had been checked to tell me which is the correct match. Or, I could play trial by error and guess. The lazy manufacturer didn't bother to indicate which driver works for my flashdrive so the tech department led me to this generic driver. The ACP-EP website provides up to five different drivers to download for the same exact product. Figure that one out, I can't. It must be an American company.

There aren't _that_ many silicon forges fabricating these. An end-vendor who does a CYA, will second-source the components and will include in his driver(s) any possible sources of chips he might use. Given that, *why you can't get your devices to work with the universal drivers* is just baffling. ||Keith's post is just noise (as is quite common for him). |Yes just the same as yourself. | Again, including at least one DATA POINT makes you look less like a 4 year old with his thumbs in his ears and his fingers wiggling.
