Step by step:
My PC has connected printer via USB (I know VID:XXXX and PID:YYYY)
I took image of my PC and put inside virtual machine (VMWare)
Of course image on my VM doesn't has connected USB-printer (because real printer is connected to my real USB-port on my real PC).
One program is running and checking accessibility of printer by check connection with the printer via USB (I don't know how exactly - maybe via WMI, maybe via other way).
Results:
a) on my real PC this program works
b) on image doesn't work
QUESTION: is possible to emulate on VM-side that USB-port (VID:XXXX and PID:YYYY) is alive?
Thanks.
P.S. I don't want to install USB-redirect-via-TCP or similar approach.
You should switch to the QEMU emulator and to Linux to do that. VMWare probably doesn't support this of thing especially in a Windows environment.
If you are already on Linux, QEMU has hardware emulation of the xHCI and you can assign the host USB devices to KVM (read here: https://www.linux-kvm.org/page/USB_Host_Device_Assigned_to_Guest).
On Windows, I don't think this will be possible.

What I want to do on my laptop:
Develop and Run on windows with Visual Studio (CUDA, TensorRT,...)
Develop and Run on Linux (CUDA, TensorRT,...)
Environment to edit videos, photoshop,...
Play games
Environment for general use (web browser, outlook, word,...)
Environment to test applications
Possibly connecting some external GPU to offload the work (cuda,...) from my laptop's graphics card. Since I'm new to this, I haven't researched enough to understand how it can be done. But, this is in my plans.
What I did and reaserched:
As a start, I created VM environements in my host Windows OS using VirtualBox for #1 and #2, but I cannot run inside VM, since it doesn't provide access to graphics card. Even if it did, I still need somehow to switch to a different environment when I want to play games for example.
I probably need hypervisor type 1 if I want to have environment to play games? But, in this case I'll need a second laptop to access it, right?
Is this even possible to do on one laptop (I have strong laptop with enough RAM and SSD)
Graphics cards (GPU) are PCI devices, so they can be passed to VMs with PCI Passthrough. A device is not accessible to the host during passthrough. Hot plug can be used to reattach a graphics card to a different VM or the host without rebooting.
I don't know if a Windows host supports GPU passthrough (maybe you need Windows Server), but Linux host and Windows guest seems to work.
Setting this up is easier if you have a second GPU that remains attached to the host or another computer to control the host during GPU passthrough, for example via SSH.
How is it possible to determine the commands to operate a usb device, if that device comes from another operating system and traffic monitoring software cannot be installed on that OS. The only method i can think of is sending random commands to the device, until the device responds, but this seems implausible for more complex commands, and potentially dangerous. For example, consider the DualShock 4 controller. Sony has not made an official driver for this device, so what method can i use to create a linux driver for it?
Get a hardware protocol analyzer. Then you won't need to install any software on the host or device under test. Here is one that I have used:

First of all, there's a similar thread on OpenQNX posted years ago but the solutions don't really apply for me.
Having said that, I want to create an OS image of QNX 6.6.0 to put on a Compact Flash card. This card is plugged in an USB adapter which is connected to my host pc. I'm running Neutrino in a VM (VMware/VirtualBox) for which I enabled USB support. Generally, the adapter works fine under Win (current host) and Linux.
The (apparently out-dated) tutorial I was following stated to search for devices named umass* or hd* after connecting the USB adapter. But there aren't any (except for hd0).
See also "ls /dev" screenshot.
The processes devb-umass and io-usb are running. So I expect that the adapter is detected automatically.
Any suggestions what went wrong?
OK, it seems that I had to restart the usb driver 'devb-umass' (several times). When the card reader is already plugged-in during the booting the driver will not detect it autoamtically. Thus one has to unplug and plug it in again after the devb-umass was getting re-started. It also might have been that the Host Controller Driver (HCD) was set to 'ohci' instead of 'ehci'.
Everything is working now as expected.

I'm trying to do mobile application development (BlackBerry, Android) on a virtual machine. My idea is that no matter what desktop I'm on I can open a remote connection to the virtual machine and have my mobile development environment ready. The problem is that I would like to deploy code to the mobile device as if it were physically connected to the virtual machine. Ideally the devices will be plugged in to the client machine that is creating the remote connection.
I'm currently using VMWare workstation to manage my virtual machines, I've done a bit of research to see what the best solution for connecting my usb devices over the network is.
There are a multitude of pricey USB over network solutions that may or may not work for what I'm trying, but I would like to avoid those. I would be interested in a free open source solution where both the usb host and usb client are windows machines. This is close to what I am looking for http://usbip.sourceforge.net/, but you can't host a device from Windows.
It appears that I may be able to do this with a Hyper-V VM and RemoteFX through Microsoft RDC, but I would like this to work on my existing VMWare VM.
The quickest solution I've found is a network usb hub that would allow me to connect the devices over the network, but this would force me to be attached to the hub which is a problem if more people come on my project.
Ideally I'm looking for an existing software solution to my problem. Any suggestions?
Also can anyone confirm this would work in Hyper-V using RemoteFX?
I would consider porting your VM over to VirtualBox from Sun (now Oracle) they have remote USB support out-of-the-box, and are very stable.
I've ported machines the other way (for work) and it's not difficult.
The rest of my team will make for my application a simple non-standard USB microphone, but until they finish it I will have to emulate it, for integration testing purposes.
Is there any risk in a physical loopback? Yes there is
Will a physical loopback work? Only with a USB bridge
There is any way to create a logical loopback? (MSDN has something about this)
There is any general purpose USB emulator software?
In case there is many options available I'd rather work it .NET/Matlab/Python solutions.
Edit: Proof of concept here
I strongly recommend this project, USB IP. It is a way of connecting USB devices over the network. There is a Windows client.
What this means is, you install the client on your Windows computer.
This device then expects to talk to a USB device connected to a Linux computer, the server:
What you now do, is either create a fake device driver for Linux, that looks like is connected to a physical USB device, but in reality is just logic pretending to be your USB device. There are tutorials for writing USB drivers for Linux. Or you create your own stub driver for the Device Control Manager (see picture above). This stub driver could run on Windows or Linux, it wouldn't matter. It could even run on the same Windows machine which is the USB client.
The DSF USB Loopback Device mentioned in the question itself, would be the same kind of solution as a stub driver for the Device Control Manager, but taking Linux out of the picture altogether.
You can write virtual USB device using QEMU.
You can duplicate already existing device, like the dev-serial.c found in this QEMU repository and change it for your needs.
After you write and compile your USB device you can simply attach it to your VM using the QEMU command line interface.
