kvm : usb (?) switching problems
 
Hello,
I recently bought TRENDNet TK-207K Usb 2 port switch. Grade to be compatible with Win and Linux.
It draws the power from USB port - no AC adapter.

Any hints would be greatly appreciated.
And i'm running Centos 5 2.6.18-53.1.4.el5 #1 SMP i686 athlon i386 GNU/Linux.

Here is the description of what sequence of events make it unusable ( until Linux reboot ):
1. boot both machines having kvm plugged in.
2. switch between them as many time as you want
3. switch to Windows and stay there for ~30 minutes
4. switching back leads to blinking led on the switch, dark screen ( i think the screensaver kicks in and that's why monitor is dark ) and no response from keyborad and / or mouse.

I have MS natural wireless combo.
Here is the log from messages right after i rebooted the Linux server and had switch pointed to it:
