data communication with a USB device at the physical level,It had to transfer the URB data to the Roothub device, Roothub to the real device.As for how to complete the communication process, specific to the hardware processing process.This is not what this article discusses unless you want to implement a real USB controller driver.How to implement remote access USB device?Through the above simple introduction, should have a general understanding of the USB communication process,We only need to
produces SDR platforms, the developer community is very important and deserves strong support. One of the easiest ways to do this is open source, open hardware. Let's talk about how the three companies are doing it.Source CodeSoftware is very important for SDR hardware. Fortunately, the three hardware supports the GNU Radio, which contains a lot of free and open source code. It also has a very good graphical interface for rapid development and testing. Hackrf and Bladerf in the GNU Radio, in th
Currently Hyper-V server does not support USB devices, if you have USB devices that need to be used in virtual machines, such as USB dongle, smart card, Internet banking u shield, etc., can be via USB over network software, using USB device.USB over network is a "client/server" software that is a powerful USB device sharing software. It is easy to use and allows you to share and access USB devices locally or online. This software contains x86 and x64
