It looks like your hardware is bad.

Can you try the 2.6.22 or 2.6.23-rc1 kernel release and see if that works better for you?  Also, please try to enable the CONFIG_USB_DEBUG option so that we get better debug messages for this.

New entries for dmesg ;

"insufficient bus power" , "hci0 command tx timeout" ? I think interesting :)

I don't think I have a problem with my hardware, because in other distros(Mostly using Linux 2.6.18.xx) , I don't have a problem. 

How can I enable the CONFIG_USB_DEBUG ?

I tried in Linux2.6.22-9-generic , the problem continues..

It looks like you need to replace your hub.  Try using a powered hub instead.  The devices you have attached to it use too much electricity for an unpowered hub.

I tried disconnect all my usb devices (printer etc.) and I used only my usb mouse, but the problem still continues, My PC have 2 usb ports, in first port, hub, second port, my usb modem, but the problem occurs, this problem effects all of ports. If my hub is problematic, why the usb modem disconnects ?

And my old distro Pardus (using 2.6.18.xx), It works perfect.

I can't answer your questions without more information.  You need to enable the "make menuconfig" option for Device Drivers/USB support/USB verbose debug messages, rebuild the kernel, and then attach to this bug report the output from dmesg after booting.
