usb sniffer linux

In 1991, one introduced the concept of pipelines in Linux and used pipelines in many places, such as file systems and device drivers. So we can see that there are various pipelines in Linux. But the same thing is that all pipelines are used to transmit things, but some pipelines transmit real material while some pipelines transmit data. The pipe we see in the USB

"Come out and try again sooner or later ." Basically, LinuxEach directory in the kernel has a makefile. MakefileAnd kconfigJust like a map of a city, a map leads us to know a city, while makefileAnd kconfigSo that we can understand the structure under this directory. Drivers/USB/storage/Makefile under the DirectoryThe content is as follows: Lfg1:/usr/src/linux-2.6.22/Drivers/

the layman. The USB device has a configuration, which we mentioned earlier, and there is another setting (setting ). A little strange, aren't these two words the same thing? Let's take our most familiar mobile phone for example. If you don't talk about the configuration, you just need to set it. Various configurations of a mobile phone may have been determined. For example, the vibration or ringtones are determined, and various functions are determin

, structusb_sg_request actually represents a scattergather request. From the perspective of our non-USB core layer, the usage of these two structs is the same. For each urb request, all we do is apply for a struct variable or request a pointer, and then apply for memory. The second step is to submit urb, that is, call usb_submit_urb ().Core will help us solve the problem. Every module in Linux provides serv

Install ubuntu on a USB flash drive and start Linux from the USB flash drive. If we install the Linux system directly on our hard disk, the GRUB of Linux will overwrite the boot guide of window. It is not convenient to carry. So I want to install a ubuntu system on a
