This question relates to node.js to read usb port signals
What is the possible way to get usb port address from windows7 32bit? For eg: If my phone is connected to one of the usb port how can i get the path/address of that USB port?

I'm trying to connect to the serial port of my Xilinx Ultrascale ZCU102 with my Macbook Pro (OS: Big Sur 11.2). The board is connected with a USB - miniUSB cable to a hub USB C connected to one of the Mac USB C ports.
With lsusb | grep Serial I get correctly listed both the USB adapter and sd card reader which compose the hub. However, I cannot figure out how to see data transmitted by the board through UART. I've tried with Serial Tools, but the two serial ports I can see does not show anything. Then, I've tried to list devices with ls \dev, but I cannot figure out what can be the device.
How can I solve?
Thank you in advance
What is needed for the physical USB connection between two Windows computers for communication between their virtual serial ports?
Should I use USB/serial adapters?
I am building a .NET terminal app on Windows 10 Pro computer that must use a virtual serial port for communication through a USB connection to the virtual serial COM port at a Windows 7 Pro computer that is running the terminal app on .NET.
The terminal app is the PortChat example app from MSDN's serial port documentation.
PURPOSE: I need to test a serial communication .NET app on Windows 10 that will eventually communicate with an embedded STM that is presently unavailable .
You need two usb/Serial adapters and connect them to each computer.
Then connect those two serial interfaces together with a Null Modem Cable.
I trying to build a software in C# on Windows 10, that send SMS with an usb GSM Modem,
the issue I am facing now, is to to identify the COM Port the usb GSM Modem is connected on, to use the right one for sending routine.
can anyone help me to get the COM Port number for an usb port on Windows 10?
If I use Tera Term, to connect to a USB OTG port on a STM32 MCU, is Tera Term a USB Device or a USB Host.
The question arises as I presumably could configure the STM32 OTG port to be a USB Host CDC or a USB Device CDC.
It's possible that it doesn't matter what I configure the STM32 USB OTG port as, but it's possible that there may be a specific standard that defines what should be done.

Neither.
Your computer is a USB host. The software running on your computer doesn't affect its role.
In my course, i need to develop a USB sniffer capture URB (USB Request Block) pass from USB device, then forward to a another PC.
For example, look at "Setting -> USB -> Enable USB Controller" in VirtualBox. When you enable this setting and plug an USB device in Host PC (Window OS), you can attach this USB device into Guest PC and read/write data or do something else in the USB device. Simultaneously, on Host PC, you can't see the USB device. If you can also detach this USB device from Guest PC, on Host PC, you can see the USB device again. URB of the USB seem to be forwarded to VirtualBox USB Driver.
I don't know what mechanism that they used? Could you please explain for me?
P/S: Can i develop a filter driver to do that?
Thank so much!
for the disconnect usb device from host and reconnect it to VM, the pattern Dynamic driver substitution has the explanation how VMware workstation does it.
for the URB part, i think USB/IP is a good start point.
