Enhancement of code of USB HUB (3)
Gniibe implemented user space approach of usb power control (in the bullet train).

Here it is: hub-ctrl-2.c. 

 HUB-CTRL  -  program to control port power/led of USB hub

  $ gcc -o hub-ctrl hub-ctrl.c -lusb

  # hub-ctrl -b 1 -d 2 -P 1 -p            // Power off at port 1
  # hub-ctrl -b 1 -d 2 -P 1 -p 1          // Power on at port 1
  # hub-ctrl -b 1 -d 2 -P 2 -l            // LED on at port 1
It found that there has been Python implementation by Vlado Handziski, and this is the discussion. Gniibe considered this tool should be in usbutils.

Gniibe wrote a patch to enable control of USB HUB.
But it should be possible to implement it only by user space.

Athlon64 kernel
The problem of decreasing interval seemed ceased.

It seems the kernel configuration variable CONFIG_HPET should be Y.

Rescan a partition table
Gniibe copied the contents of disk to another disk by 'dd'.

Gniibe wanted to mount the new disk, but it required to rescan partition table.

Don't know how, so, invoked cfdisk and wrote partition table (untouched), then it rescanned.

Are there /sys/block/*something* to do that?
