i just purchase a few set of gridseed 5 chips usb miners to mine litecoin.
but i only got about 10 kh/s for each miner when i setup bfgminer to mine.
any idea why i can only get so low speed ?
i use litecoinpool.org
tks

Not much info there. What's the clock speed set to?
I'm using dmaxl's cgminer on the 80 chip version and seeing 5,317 kH/s by litecoinpool's reckoning. You have 1/16 as many chips so I'm guessing you should see about 332 kH/s.
If you're using cgminer try adding the line
"gridseed-options": "freq=800"
to your cgminer.conf and restarting. Ooops, just saw the bfgminer in your post I used that briefly, don't know how to set the speed. It's probably similar since one is a fork of the other. Are you seeing any hardware errors" I see HW:0.
Oh, those things are USB powered, right? You're going to have similar power issues to stickminers, need to use a hub that can supply a fair bit of current to each USB jack. A symptom is that one miner runs well but when you plug in several they slow down. A good hub from the Gekkoscience threads is https://www.amazon.com/Superbpag-Portable-Charger-Transfer-Samsung/dp/B013OK10YM It might be overkill for Gridseeds but it eliminates one worry.
Oh, and even with 80 chips I make about $0.20 per day so don't expect to get rich.
