Enumeration is to read some information from the device, know what device it is, how to communicate, so that the host can be based on this information to load the appropriate driver.To debug a USB device, it is important that the USB enumeration process, as long as the enumeration succeeds, then it is half the success. In the USB architecture, the hub is responsible for detecting the connection and d

Basic Nat only converts IP addresses instead of ports. A basic Nat usually requires multiple public IP addresses to meet the needs of applications with the same port in multiple Intranet nodes.Program. This type of NAT device is not common because of its large limitations.

2. Solution
Separate the connection and initialization of Peer services in a networked application from the processes executed by these services after the connection and initialization.
Specifically, the application service is encapsulated in the peer service handler. Each service processing program implements half of the end-to-end services in networked applications. Use two factories to connect and initialize peer services: receivers and connec

According to foreign media reports, anti-virus software expert Bitdefender recently found that nearly 19% of iOS apps will access the user's address book without the user's knowledge or consent. In addition, 41% of applications track users' geographical locations. Most reassuring is that 40% of the applications that can obtain user privacy information do not encrypt the information.
However, this situation will be improved by the release of iOS 6 this
