Where do I start if I want to create a virtual USB device (for example, a virtual USB mouse which looks like a real USB mouse attached to a USB port) for testing/learning. So far what I understand is the HIDClass driver (hidclass.sys) has a minidriver for the usb bus (hidusb.sys) that carries out the enumeration of attached USB hardware.

Dear sirs, This my first post and I would like to apologise in advance for any mistakes. The first post is with the drivers disabled by me and this one is as it was after all the steps I took.I would like of course first of all to thank you for taking the time to assist a complete stranger.I guess internet is not al bad.I would also like to ask you if it is o.k and it will help to post the link to my earlier advisor.So here are the details: Aladdin USB Key USB VID_0529&PID_0001&REV_0100 1&79F5D87&7&01 The drivers for this device are not installed. Aladdin USB Key USB VID_0529&PID_0001&REV_0100 1&79F5D87&7&02 The drivers for this device are not installed.

Emagic mt4 midi interface drivers windows 10. Thanks again. Hi Iraklis1957,,, and welcome to TechSpot! You must have a USB security device connected to your computer.

It looks like a flash drive - but it's not. Do you have anything that looks like a flash drive connected??

If you open Device Manager you see a device with yellow icon. Once the USB security device is removed, the device and yellow icon will disappear. Next, question: Where did this device come from?? It is typically used to protect a software product (where the software won't run unless the device is connected AND its drivers installed). ​ But we can change the Device Manager view so that it displays devices 'by connection' (this shows how devices connect to one another).

Let's change the view > At the top of DevMan menu click View->Devices by connection. > Click to expand each ACPI devices and then the PCI bus > Expand the the devices under PCI Bus to find the Alladin USB Key Is it listed? Please post a screen shot. Here's an example for my case when I view 'by connection'. It reveals the web cam is connected to the USB bus. What do you see?

Let me have a look so I can try to interpret the connections and where the Alladin key fits in. Dear sir,all my paid programs are o.k and as for free trials I try to avoy them,with the exception of a very,I believe,fine anti virus program and the from time to time necessary for the task needed freeware programs.I don't usually, if it's possible, leave comp.

Issues unresolved but this problem was way beyond any of my skills if I had any to begin with.But as we Greeks say 'If you ask the rjght question.' .If you still believe it will help I can post all my installed programs but and please don't think,I'm ungrateful,I'd rather not. Best regards. Not a problem. I completely understand. Run MyUninstaller. Click View to do the following settings > Show Windows Update - off > Show Office Updates - off > Show Items with no Uninstall - ON > Show system components - off That should reduce the number of entries displayed.

Next, click on the column header labeled Company. This will alphabetically sort the entries by the vendor. You can ignore anything still listed from Microsoft. Do you see any Entry Names or Companies with perhaps tell-tale words like Virtual, Alladin, USB etc.

That we might suspect? I don't see anything that looks like a uninstaller for this thing in those entries Check this next: How long has this problem been around?

Would have an old System Restore Point with a date prior to this problem? You can find screenshots of what I'm referring to > Choose System Restore from the Programs menu > What's the date of the recommended restore?

Is it old enough?? Then we'll use it. > If not, select Choose a different restore point. Do you see anything with a date old enough?

Then we'll use it. If there was a restore point with a date prior to the problem, try doing a System Restore. If not, my next question. Do you have your machine backed for worst case?
