William, 

Thanks for your reply :) 
luckily I got the first one as a gift few years ago :D
I've found another Powered HUB at my local area Craigslist, will find out how it works...
This is how it looks like
http://www.kensington.com/kensington/us/us/p/1505/K33935US/pockethub%E2%84%A2-4-port-usb.aspx

Hopefully the only issue is because of the non-powered HUB, really don't have time stuck in this USB mystery :(

IMHO: The first one is crap! I hope it was cheap :)

I would use the second one.
I have a setup here that powers both the Gumstix and the hub from the same
3A 5V adapter.

Hi James & William,

Is that means once I plugged in a powered usb hub and my device should work
w/out any problem?
The one I'm using (Belkin as well) is like the one in following link:
http://www.amazon.com/Belkin-F4U006-RED-Port-Travel-USB/dp/B001TK3R1O/ref=sr
_1_4?ie=UTF8&qid=1351642934&sr=8-4&keywords=belkin+usb+hub+travel


For the powered hub, I've found one on Amazon which looks like:
http://www.amazon.com/Belkin-4-Port-Cable-Power-Supply/dp/B00004Z6KW/ref=sr_
1_7?ie=UTF8&qid=1351642766&sr=8-7&keywords=powered+usb+hub


you guys think it's a good idea to get this hub?
Thanks :D

James
