Adaptec Aha-2940au Pci Scsi Controller Driver Windows 7

Owners of SCSI scanners often face problems after having migrated their systems to Windows 7 64 bit or Windows 8 64 bit. While Vuescan does support most SCSI scanners on these operating systems a suitable driver to keep using the required SCSI host adapter is often missing.

Neither Microsoft nor Adaptec officially offer such a driver for download. Only more modern Ultra160 SCSI controllers received official drivers for 64 bit Windows. Cables to adapt scanners to such controllers tend to be expensive and even after successfully connecting a scanner it often would not work properly in our tests.

The missing driver that allows you to keep using the proven and nowadays cheap to obtain SCSI host adapters like the various versions of Adaptec's AHA-2940 does exist for both Windows 7 64 bit and Windows 8 64 bit though. In the following we will show you how to get your scanner operational again while keeping its original SCSI controller card.

Please note that you are using this information at your own risk and that we can't provide support for this. Of course that doesn't mean we'll not answer questions or are not interested in any problems you might encounter.

Besides allowing you to use Vuescan the same method might also allow you to use the manufacturer's original scanner software. That should at least have been compatible with Windows Vista though because otherwise chances are that it won't even be possible install it anymore. Vuescan does include the required drivers for the scanner itself so that its recognition by the system should work without problems.

Our modified driver supports Adaptec's SCSI controller series AHA-29xx, AHA-39xx and AVA-29xx

It would be appreciated if you would report to us if you were able to use this driver with another controller from our list. Also please let us know should we have missed to include one that uses an AIC-78xx chip as well.

Creating a driver for Adaptec's AHA-2940 SCSI host adapter et al. on Windows 7 64 bit & Windows 8 64 bit

Our base for the SCSI host adapter's driver is the emulated driver for these controllers that shipped with Windows Vista 64. That emulated driver is sufficient to run a scanner because doing such does not require an ASPI layer. Apart from this page's instructions you will require a *.sys file which can be obtained from any Windows Vista 64 bit DVD. That could be a recovery disk for Windows Vista Home 64 bit for example. On the disk you will find an archive file named install.wim from which we will have to extract two files.

In case you have misplaced your Windows Vista disk and require a trustworthy source to obtain this file on-line it can be noted that Microsoft used to sell Windows Vista through its partner store Digital River and that the according install files still reside on Digital River's servers. We found working download links from the official Microsoft partner's servers listed on a web page named

After having located the install.wim file please download and install the universal archiving software 7-Zip. It allows you to open the install.wim file in which you'll find a folder structure. The two files djsvs.sys and djsvs.inf which we require are located in the folder: 1WindowsSystem32DriverStoreFileRepositorydjsvs.inf_6451fbc2 Please create an empty folder anywhere you like on your systems and extract the two required files there. Note that the source must be a Windows Vista 64 bit disk (the djsvs.sys file is 87KB in size). The smaller djsvs.sys file included with Windows Vista's 32 bit versions is not suitable.

We will now modify the driver so that the supported SCSI controller cards will be recognized on Windows 7 and Windows 8. Please open the file 'djsvs.inf' in a text editor of your choice and replace its contents. In order to do so click into the text box below this paragraph, press Ctrl+A and the Ctrl+C to copy the text. After having done this switch to your text editor and inside of it press Ctrl+A followed by Ctrl+V to paste the copied text while replacing the old contents of the file.

Adaptec Aha-2940au Pci Scsi Controller Driver Updater

Save the file, go to Windows' Control Panel and choose System > Device Manager. When using Windows 8 please follow the instructions at the bottom of this page (which will also let you end up in the Device Manager) before you go on with the instructions below the screen shot.

The screen shots for the following instructions were taken on a German copy of Windows 7. Because things will look extremely similar on an English OS we did not take them twice.

On Device Manager's device list look for the 'Other Devices' category where you will find your SCSI host adapter’. The corresponding entry will be named 'SCSI Controller' or something like that. Right click this entry and select 'Update Driver Software'. Next select 'Browse My Computer' and specify the folder you created before. A warning message will be displayed which you will need to disregard - telling the system to go on with the installation. Afterwards your SCSI host adapter should be listed under its correct name , e. g. 'Adaptec AHA-2940/2940W (AIC-7871 PCI SCSI Controller Emulated)'. If a scanner is connected it should now show up in the imaging devices category and a corresponding driver that was installed with Vuescan should get installed automatically. If the driver does not get installed you can always install it manually from your Vuescan folder.

Installing and using unsigned drivers on Windows 8

We don't use our scanners on Windows 8 but user feedback tells us that in order to install the driver created above one needs to start Windows 8 in a special mode first. Getting Windows 8 to boot in that mode involves a series of steps of which we provide screen captures below. The screen captures come from a virtual Windows 8 machine and since FireWire devices can't be passed through to that virtual system we won't show the actual driver installation.

First get the Windows 8 menu to show and click the gear icon at its bottom. On the settings screen click the 'Change PC settings' entry. There choose the General category from the 'PC settings' list and scroll down all the way to the end of that category to reach the 'Advanced startup' entry as shown. There press the 'Restart now' button.

Your system will restart and after a while you'll get to this option screen. On it choose Troubleshoot, then choose 'Advanced options' and finally choose 'Startup Settings' where you'll find yet another Restart button. Press it to reboot to the 'Startup Settings' screen and on it press either 7 or F7 on your keyboard to boot Windows 8 with its driver signature enforcement disabled.

After booting Windows 8 that way choose Search from the Windows 8 menu, enter 'devmgmt.msc' and click on the App found to get to the Device Manager. Now install your driver as detailed above for Windows 7.

With this information you should be able to get the SCSI host adapters AHA-2930CU, AHA-2940/2940W, AHA-2940AU, AHA-2940U/UW, AHA-2940U/UW/D, AHA-3940U/UW/UWD, AHA-3940U/UW, AHA-2944UW, AHA-3944U/UWD, AHA-4944UW, AHA-2940UW Pro, AHA-2930UW, AHA-294x, AHA-3985, AHA-2944/2944W, AHA-3944/3944W, AHA-4944W/UW, AHA-3940/3940W and AVA-2902, AVA-2904, AVA-2906, AVA-2930 operational on Windows 7 64 bit and Windows 8 64 bit even though Microsoft and Adaptec have officially decided not to support them anymore.
