Depending on the USB protocol, if the USB cable has been idle (idle) for more than 3MS, the device should treat it as a hang (Suspended) signal, require the device to enter a suspended state within 10ms, and reduce the current required by the device to the specified value (for Low-power devices, The requirements are 500µa, while for high-power or for devices that support remote

Wake-on-lan, known as WOL, is a power management feature that allows a device to wake the operating system from standby or Hibernate mode if there is network activity. Many motherboard vendors support IBM's proposed network wake-up standard. This standard allows network administrators to remotely turn on PC power for file upgrades, resource tracking, and device i

One, the communication between multithreading.Is that multiple threads are manipulating the same data, but the methods of operation are different.For example: For the same storage block, there are two storage bits: Name sex, existing two threads, one to which data is stored, and one to print.In order to solve the security problem in the above problem (the print thread cannot manipulate the common data while the storage thread is holding the operation), the two threads should beSynchronize the co

) { condition_wait (Cond,mutex); } This is because there may be a false wake-up "spurious wakeup" situation.That is, even if no thread calls Condition_signal, the function that originally called condition_wait may return. At this point the thread is awakened, but the condition is not satisfied, this time if the condition is not checked and down, it may cause the subsequent processing error.Spurious wakeup can occur in a multiproces

Wake on the network, WOL. Simply speaking, the computer is in the shutdown state, you can send special packets to the network card via the Internet, the network card after receiving the specified package, turn on the computer. WOL requires hardware to support this feature, the current market mainstream Ethernet card support WOL function, and wireless network card to find a number of not found to support the function of the wireless card.I have success

First, the control of the Windows 7 system leaving mode Users who are familiar with Windows 7 and Windows XP should know that Windows 7 has a more than Windows XP exit mode in power management (what is Exit mode?). When the user has left mode enabled, you can let Windows 7 implement the "Sleep Download" feature. But in many cases, because you or someone else doesn't mind moving the mouse, Windows 7 will wake you up from a deep sleep. As we all know,

We use the following command to determine whether laptop_mode is enabled for Laptop. if the result is 0, it indicates that laptop_mode is not enabled. if it is not 0, it indicates that Laptop is started.
