used can pop corn and plastic bucket 6 inches depth and usb chord .
made cantenna with bucket dish, put chorded cantena inside bucket.takes 5 sec to make. good 153kb=19KB per sec in windows gaining as shown by free download manager and netmeter.
isp giving 153 my gain now 153.

yesterday connected puppy 4.3.1 with upgrade 4.3.1.1
but today things are gloomy.
somehow ttyusb3 is attached which starts module cdc_acm and other 3 modules.
got to lot of modprobe -r cdc_acm and other 3 modules.
sometimes pupdial shows no carriesr detect.
needs lot of reboot to overcome .

download 124 kbps
upload 31 kbps
My optimum is 153kbps download
153/2=71 kbps upload in windows xp sp3

wvdialconf /etc/wvdial.conf
helps lot to find ttyusb0

this is pmodemdiag with usbserial as module running

Doing all this in puppy 4.3.1, uname -r 2.6.30.5 user agent sea monkey 1.1.18 from speed 153 kbps.
but speedtest.com shows half of it , this happens in windows too as i am in conjusted area with lot of subscribers.

In wary 5.2.2 it seems option module is working for usb modem so needn't have to do anything .since boot no keytouch found 3g modem message shows.dmesg shows ttyusb0 attached.then pupdial modem probe found usbmodem.Now give username password dialcode.connect. It's connected.
Thanks everybody on help ...

if #lsusb in console do not find 21f5:2008 then mode not switch
evoke usb_modeswitch manually.
#usb_modeswitch -c /etc/usbmodeswitch.d/21f5:1000
then success message will come
either attach option or usbserial
#modprobe -v option
#new_id file is now permissible
sudo chmod 774 /sys/bus/usb-serial ...

Thanks for helping due assitance usbmodem working.
