Hi I know STM32F401 Discovery boards and STM32F407 boards can be used to integrate with external Ethernet boards (DP83848). But I need to know whether I can use STM32F401 Nucleo boards (STM32-F401RE) to connect with external Ethernet boards?
Thanks in advance.

I have a GSM LTE evaluation board which contains a USB slave device port and a evaluation board for microcontroller which also contains USB slave device.
I want to send commands to GSM module using the controller boards through USB.
After browsing couple of hours on internet i didn't find anything helpful.
My question is that is there any possible way to communicate two USB slave device??
Any help is appreciated...
Thank you in advance
Two USB devices cannot communicate directly one to another. Unless they support OTG. In most cases it is needed USB host controller between those two USB devices to provide some kind of link between them.
this is a more HW question. I was wondering, is someone aware of a device which enables to connect a USB device to a PC over WiFi?
The idea is to plug USB device into a transmitter and have a receiver at the PC side. The data would be transferred wirelessy.
I have learned that the key word for this type of devices is WUSB. However, I am failing to find a successfully stories behind using some of these, as well as a good device.
Does someone have an experience?
Thank you in advance.
I haven't seen any USB hubs that can transmit over Wi-Fi. But there are several Wireless Hubs available. Like these

They have an adapter you plug into the PC and the hub works just like it would if it were wired.
Why do you need it to transmit over Wi-Fi specifically?
I'm looking to control a bunch of LEDs from my Android phone, with a TI MSP430 or similar.I want to communicate vis USB. The MSP430 has a USB port, but I can't find any information about using the USB port for anything besides programming the chip. Is there a way around this, to use USB to communicate with the board?
I want to connect a USB peripherals to a FPGA. Basically FPGA should act like an USB host. Is there a FPGA board support a USB hub so that one could connect multiple(upto 4) USB peripherals at a time.
I have a Digilent Nexys3 fpga which is based on Spartan 6. It supports only one USB device (keyboard or mouse). It doesn't support a hub. I have found Cypress host controllers, but I am not sure how to use it in a FPGA.
You need to have a USB host controller inside your FPGA, such IP is not freely available, one alternative is to use a Zynq based (for Xilinx) or Cyclone V based (for Altera) board. Those have integrated USB controllers connected to their dual ARM core.
You can find more info about those at:
Altera Cyclone V
Xilinx Zynq
You maybe able to use an external host controller but then you have to connect it to your FPGA and that is usually requires a lot of IOs and those modules are more expensive than buying a Zed board ($395) or Cyclone V board ($450).
The Arduino Nano (and other models) has a USB Connector on the pcb.
Can a Arduino Application (Code inside the loop() Function) communicate to a PC/Mac over the built in USB Channel?
The board at the link you posted uses an FTDI USB to UART chip; the ATMega168 itself has no USB controller. The UART side of the FTDI chip is attached to the ATMega168's RXD/TXD UART pins. So from the point of view of the Arduino code, you are just communicating with a UART driven serial port.
From the PC end, the FTDI chip uses the USBSER.SYS driver to emulate a legacy UART serial port (A Virtual COM Port or VCP). You will be able to see this and which COM port it has been assigned to in Device Manager.
So in essence all you need to know is how to do serial port programming on both the PC and the Arduino and you are good to go.
This is how I have done it. You also need to write a program to your computer - for POSIX-compilant OSes, this one could help you out.
