USB/IP supports a function to import USB devices from application-side
machine by attach command.
The usage is as following.
dev:# (Physically attach your USB device.)
dev:# insmod usbip-core.ko and usbip-host.ko
dev:# usbipd -D
// Start usbip daemon.
dev:# usbip list -l
// List local USB devices and their busid.
dev:# usbip bind --busid <busid>
// Make a device exportable to other hosts.
app:# insmod usbip-core.ko and vhci-hcd.ko
app:# usbip list --remote <host>
// List importable USB devices from the <host>.
app:# usbip attach --remote <host> --busid <busid>
// Import a device
By attach command, connection will be established from application-side
to device-side.
This patch introduces a function to export devices form device-side
machine to application-side machine.
The usage is as following.
app:# insmod usbip-core.ko and vhci-hcd.ko
app:# usbipa -D
// Start usbip daemon.
dev:# (Physically attach your USB device.)
dev:# insmod usbip-core.ko and usbip-host.ko
dev:# usbip list -l
// List local USB devices and their busid.
dev:# usbip connect --remote <host> --busid <busid>
// Export a device to <host>.
For this, export function, connection is established from device-side
machine to application-side machine.
Following use cases are supposed for the export function.
1) Server application or cloud service serves distributed ubiquitous
devices.
2) Dedicate devices to server application or cloud service.
To connect to cloud service, it needs to connect from inside of
firewall.
Probably, the export function was planned because the packets have been
defined in a header file (usbip_network.h) but it not yet used.
This patch fixes the defined packet structures (ie. int in reply to
uinit32_t) and use them.
Also, vendor/product name converion is added to port commnad as same as
list command.
