I'm having some big issues with my Gridseed 5 chip miner.
The issues are:
1.When I used the official miner (CPUMiner one I think),no matter how many times it shows 'Dispatching new work...' I never see any shares submitted to the pools I use (no matter which pool I use and with their corrent URLs,clevermining.com,multipool.us and coinshift.com) so I gave up ever hoping I'd get the full 400+Kh/s as promised from my miner so I changed to CGminer 3.72 which does get shares submitted but I get much less than half of the total hashpower/coins I'm supposed to have mined on all the pools I've used.
2.CGminer often says accepted yet I never see the shares in my pool even though my internet connections ok and plugged in ok via the USB port.
I've tried everything I know of to remedy this but to no avail and am pretty frustrated now since there's no improvement and the instructions are even harder to understand than why I'm having issues in the first place.
If someone can just help me get back on track,I'd really apreciate this as I didn't spend nearly £300 for a miner that only performs at 50% or less of it's capacity (paperwight).Thanks

First, you're not going to get a stable 400k hash out of a gridseed. You'd need to be running at 950 to do that, and you'd be getting a number of HW errors if you did. I've been running pretty stable at 900 with a couple of HW errors but this gives about 380k. Most people run it at 850 which is around 360k.
This is what I use for cgminer:
cgminer.exe --scrypt -o yourpooladdress -u username -p password --gridseed-options=baud=115200,freq=900,chips=5 --hotplug 0
If you get too many errors, change 900 to 850.
With cgminer, you'll see a low WU. Ignore it (it's incorrect). If cgminer is showing a correct "A" count (depicted by A: in the output) but you're not seeing it on your pool, be sure you have the correct wallet address. A number of pools gladly accept "donations" from people with incorrect addresses.
If none of this applies to you, post sample output from cgminer so we can see what's going on.
