This patch is the new application(vhci)-side daemon specific code.
The daemons are consisting three files.
usbip.c : common code.
usbip_dev.c: device(stub)-side specific code.
usbip_app.c: application(vhci)-side specific code - this patch.
Here, device-side daemon is EXISTING-1 and application-side daemon is
NEW-1 in figure below.
EXISTING) - invites devices from application(vhci)-side
+------+ +------------------+
device--+ STUB | | application/VHCI |
+------+ +------------------+
1) usbipd ... start daemon
= = =
2) usbip list --local
3) usbip bind
<--- list bound devices --- 4) usbip list --remote
<--- import a device ------ 5) usbip attach
= = =
X disconnected 6) usbip detach
7) usbip unbind
NEW) - dedicates devices from device(stb)-side
+------+ +------------------+
device--+ STUB | | application/VHCI |
+------+ +------------------+
1) usbipa ... start daemon
= = =
2) usbip list --local
3) usbip connect --- export a device ------>
= = =
4) usbip disconnect --- un-export a device --->
