[ballotum]

Hi!
i have a nokia 770
i tried to connect a usb keyboard @ like this schema

http://img110.imageshack.us/img110/7799/connectionyt7.jpg

it was saying pc connected and i was able to see the holy usb icon :)

then i tried to connect a usb keyboard but i failed after it i searched for it @ web i did see some guys says "u have take u n770 to usb host mode on"

i downloaded the flasher utility
but I get the following error:
'Syntax error: "(" unexpected'
after i searched for it @ web
i have seen that :)
"Flasher has to be run from a separate Linux box!"
but when i do
echo host > /sys/devices/platform/tahvo-usb/otg_mode
n770 doesnt say it has been connected but it's light turns on ,
but it doesnt work too
when i execute "dmesg" cmd from xterm
sometimes i see usb connected ,sometimes no usb host controller, etc
i tried also
echo slave > /sys/devices/platform/tahvo-usb/otg_mode
too
but when i try 2 restart it gets default value to "peripheral"

i have no any linux pc but i have kubuntu 7.0 live cd
so my question is? what is wrong? configuration or the holy flasher && usb host ****? :confused:

or can anyone help me from msn messenger step by step :o ?

sorry about the bad english & picture

# Update:
" i know i connected a barcode reader beacuse my flexible usb keybord was @home but it should work too"
thanx for ur replies
