[0037] c) Configure the hardware device information of the virtual hardware, such as PID, VID, physical serial number, name, description information and the like.
[0039] S4, multiple USB virtual devices are identified through the operating system and added to the device list.
[0046] 3) The application program obtains and uses the returned result submitted by the host control driver.
[0049] The USB request fine-grained slice management and coordination needs to consider the characteristics of the USB hardware, from the following aspects:
[0053] According to the different characteristics of the equipment, the solution to the equipment request coordination is implemented in the following ways:
[0056] (3) For a hardware device with a state machine, the host does not need to do too much coordination to control the driver.
