BIG THANKS guys - Great job!
Here is my result:
first a couple of times did not work properly(may be around 7-9).
I fallow strictly all rules that MohammadAG wrote in his first post.
especially that one:-first because I was in a hurry, I did not pay attention that I miss to install i2c-tools, that was fixed after first reboot, but still the things did not worked...
-after an hour of rebooting and hunting the time between Start BME and connect USB now - I was too excited so I needed an hour to coll down... waiting the light of my drive to light on...

Finally I got the multimeter and plug one naked female connector and start looking what and when is coming out form N900? I have 5.12V even with less than a half empty battery.
So the sequence for me working ONLY IF I wait to plug my usb/hub/mouse/keyboard/usb2sata(IDE) controller as fallows:
1st-Click Hostmode VBUS, 2nd- Start BME, 3rd-Connect now USB and finally - wait 5 seconds, then everything is working, USB Flash powers up, then I need to press mount /dev/sda1, and Ye-it works!
If I connect before that it does not work!

There a small issue when connecting only single flash drive flexxxv wrote about it but with HUB+external power the issue not present.
I tried to connect the fallowing things:
1.flash drive 2GB /Transcend-Bamboo/ FAT32 - WORKING!
2.HDD 2.5" 320GB Transcend-StoreJet - 160GB NTFS + Truecrypt second partition - it appiared in /dev/sd*, but can not be mounted, no ntfs kernel module loaded, tried to install and load form stock kernel but failed (witch was obvious but..).
3.flash drive 8GB Kingston - Travelstar - NTFS - same stroy
4.keyboard GuoYu - working after connect/disconnect/connect - not all keys mapped correctly (digits and ctrl,shift,alt not working)
5.mouse usb wireless 2.4GHz Logitech VX Nano, some kind working but not correctly.
6.usb to SATA/IDE/2.5"IDE converter 1st connected with 2.5"IDE2CF (4GB SANDISK Ultra - 3 ext2 partitions), tried to mount failed for unknown reason?? its appeared in /dev/sdc1,2,5 kernel module for ext2 is there but fail.
7.usb to SATA (same adapter) connected to LG DVD RW, with external supply - no success here at all /for now/

!!!PLEASE WARNING DO NOT TRY THIS!!!
Clicking on VBUS default - cut off the power (5.12V) coming form USB, but Hostmode CHARGING not working for me...
!!!PLEASE WARNING DO NOT PLAY WITH THIS!!!

I will not have time to make patches right now, but I'm ready to test more, more devices like usb2wlan, usb2lan , Web cam (just for fun), all-in-one card reader, smart card reader (I'll banking from N900 ...and more
Some not good pictures ...
