[Qemu-discuss] Dumping USB Packets

[Jordan Bouyat]

Hi !
I recently grab a dummy usb
driver(https://github.com/pkt/qemu-dummyusb/commit/c5f61398dcebc9831f4ca409553ae85b438f27a2)
and modified it to behave like an HID mouse with the help of
(hw/usb/dev-hid.c).

It works, but my goal is to dump the whole USB packet in order to modify
it or replaying it.
I spend some hours to search in the source code, but the only data I
succeeded to dump are the content data of the USB packet in the
usb_dummy_handle_data() with the uint8_t buf[p->iov.size] variable.

I also search in the USBDevice strucure (include/hw/usb.h) with the
attribute data-buf[4096], but didn't succeed. I also don't find where data are 
in USBPacket strcture.

Could someone help me ?
