hi all: I have some questions: 1. if I need to capture all the data host capture from bus, usb mon binary can reach this goal? 2. if #1 is Yes. from usb mon text I need a. compile kernel with usbmon support b. access /dev/usbmonx c. feed the binary file to wireshark. in b), shall we write a user mode program? if so, is there any sample flow I can reference? 3. if #1 is No, is there any default kernel config can do that? or I should write memcpy by hand in urb_complete?
