Hot swap

[picosoft]

Hi,
I'm now using Raspberry3 board and touch screen.
This goes well, but, there is one problem.
Touch driver, TSLIB, cannot support the hotswap.

I have to support the hotswap on the usb touch driver.

So, without tslib, there are 2 methos.

1. Direct input(evdev) to Qt.
2. using xinput on X11.

There is no calibration by 1, so, I cannot use this.
But, 2 is very difficult how to do.....

Please, let me know how to do.
Thanks in advance.
