This far its been some adventure getting these usb miners to work
It looked all simple but it can be less simple just because either hub or usb ports might mess up
I had bought 5 usb erupters from a group buy, and since i received these things been trying to get them to work all 5
Now here comes the crazy thing some work easy others don't
Also had struggled with the jalapeno but since i installed the latest FTDI driver it works easy with bfgminer
Since that i wanted to add the block erupters which i will call amu's from now on i had to try many things
First i tried to get them working with bfgminer but it does not see the amu's
So i took cgminer 3.3.1 and poof it does see 2 amu instant but was whining about the wrong driver
Then i downloaded the zadig driver tool at first zadig does not show any devices
You have to select in the top bar under options list all devices
Then it shows the uart bridge controllers if you plugged all in
This might get confusing or might not even work easy
I found that best way for me was when i had one stick in and reboot after i changed that driver into winusb
people said that only once the winusb driver has to be installed but that does not work on my machines
After that its best to reboot your machine when the zadig has stopped searching
Do not start before it ended the search because windows instant message restart now just wait till that search ended.
I am not sure if its really is needed to wait but to be honest better safe then sorry.
I had to select each and every one of them separate to get the amu's to work
So i took all out besides the one allready installed
You can start cgminer with the mentioned parameters and you see the amu starting to mine at your pool
Then i started zadig again and put the next stick into a free usb slot in cgminer you get the message that it does not have the right driver. Which is libusb by default for windows sadly the rename driver does not work else it would have been easier to see which one has been changed properly.
You select again list all devices in zadig en you will see an newly added uart and when you click on it in zadig you will see in the first box what driver it shows in my pc it showed libusb.
So i changed that by choose install winusb driver.
Now windows whines about reboot again you do not need todo that simply pull the last added amu out and reinsert it.
Meanwhile keep an eye on your running cgminer you will see it being added and a few seconds later it starts hashing like the first
Keep doing that with all of your amu's till they are hashing like they should
After i got them all plugged in from 5 i found 2 stick where giving alot of HW errors and where not sending any shares or at least hardly any.
I think these are flawed/broken sticks ( after 1 day working one of them does not mine at all anymore ), currently trying to get them replaced before i order more of the amu's
Now to make this story even more complex cgminer does not find the stupid jala but guess what the bfgminer finds the jala instant.
But bfgminer refuses to find the amu's
:S
I have been messing with this for several hours and really do not understand why it does see one or the other but not both
There are posts from people who seem to have any hardware running on cgminer and bfgminer but somehow for me its a mess
It might have todo with me running win8 but i am in the proces to buy such a solution like the raspberry pi although i see people having issues with them as well
Some usb hubs gives issues and usb 3.0 ports can be a some work as well, in most cases a pc has usb 2.0 and usb 3.0 slots as soon as you got the amu's to work on the usb 2.0 slots you get them to work on the 3.0 slots as well is what i found out.
I found some ports on the mainboards are shared ports and have a limited power output look carefull at the specs of your mainboard if these ports are shared hubs.
For instance the board of a friend an gigabyte board has 4 usb ports which are actually 2 REAL usb ports but being split into 4 which obvious gave an issue if put 4 amu's in those 4 ports when he took at 1 and put that into the front usb ports they ran fine.
