My question is connected with the following:
/* specific usb messages, also sent in the 'pid' parameter */
#define USB_MSG_ATTACH 0x100
#define USB_MSG_DETACH 0x101
#define USB_MSG_RESET 0x102
This is some lines, in "usb.h" file in qemu sources. Is this some type of
standard, and where I can read documentation, about?
I want to ask also the following. If some device is connected to USB port,
and I reset the port - what happen? In qemu sources we have:
1. Something (non interesting for me) ...
2. Reset all devices.
3. Change the state of devices from "reset" to "attached".
Is this normal? To enumerate device (i.e. SET_ADDRESS) it is necessary to
reset explicitly device first (reset port is not *enough*).
R.
