Avalon Nano mining help

[RoyalScopez]

Hello BitcoinTalk!

I came here, because I guess this is the best place to find solution for my problem!

I have 2 Avalon Nano 3.6GH/s USB Miner, my OS is Win7, and want to use BFGminer (I read that this is the easiest way and read somewhere that they don't want work with cgminer)
I don't want to use the original GUI, because that GUI is chinese, I don't understand it, and it creates an "Avalon Services" app, what is run with windows boot and somehow uses a lot of CPU and memory.. so no I just don't want to use that.

So the situation is the next... I made them work, but they only want to work individually. Here's my settings for them:
bfgminer.exe -S ICA:\\.\COM3 -S ICA:\\.\COM4 -o pool stuff -O login stuff --set-device ICA:baud=115200 --set-device ICA:reopen=timeout --set-device ICA:work_division=1 --set-device ICA:fpga_count=1 --set-device ICA:probe_timeout=100 --set-device ICA:timing=0.22 --api-listen 2>log

If I point the BFGminer directly to these COMs then the BFGminer think about like 2 minutes and give me this screen: http://kepfeltoltes.hu/150214/736150235Avalon_2_www.kepfeltoltes.hu_.png (yea I know "all pools are dead" it says but it works). The log says this: Started bfgminer 5.0.0
 [2015-02-14 05:20:05] Found ICA 0 at \\.\COM3
 [2015-02-14 05:21:48] Found ICA 1 at \\.\COM4 -> but as you can see it doesn't hash

If I use "-S all" in the settings then the BFGminer thinks about 2 minutes at the start and the device works what I used the last time! (so if I tried to use COM3 then COM3 will work, and the same goes for COM4)... if I switch the devices place then it also work like a dream, so the devices are good, I tried to place device 2 (COM4) to somewhere else via a USB cable, it changed to COM6 it's ok, but then the problem comes up what I wrote above.
Log for "-S all" option: Started bfgminer 5.0.0
 [2015-02-14 06:31:13] Found ICA 0 at \\.\COM4
 [2015-02-14 06:33:01] ModMiner detect: no response to version request from \\.\COM3

For example I tried only run COM4 worked like a dream, then "-S all" and here above you can see only working what I used last time succesfully, in this example COM4


I tried to use one more instace of BFGminer, but I have several problems with that... then there's an api problem and tries to reconnect every 30 seconds (I'm missing something here) and then in the 1st instance of BFGminer's hashrate just drop lower and lower like to 10% of the original hash speed, and anyway what if I want to use like 10 Avalon Nano in the future? I can't run 10 BFGminer

I like you have been having trouble with the nano.  I got a link for you to try let me find it.

Thanks for your help!

Deleted the duplicate thread but kept your one reply below. Please don't post the same question twice.

Hmm, I'm not sure what your problem is. The Avalon Nano doesn't seem like a very common stick miner (it was a little late to the party).

According to the bitcoin wiki you need these settings in your bfgminer bat (it looks a little different from what you have):

Code:

 bfgminer.exe ^
       -S ICA:\\.\COMn ^
       -o stratum+tcp://stratum.ozco.in:80 -O mikeqin.avalon:1234 ^
       --set-device ICA:baud=115200 ^
       --set-device ICA:reopen=timeout ^
       --set-device ICA:work_division=1 ^
       --set-device ICA:fpga_count=1 ^
       --set-device ICA:probe_timeout=100 ^
       --set-device ICA:timing=0.22 ^
       --api-listen ^
       2>log

It's also possible you need the USB to UART driver (if you haven't installed it).

I wouldn't suggest you buying any more of these miners if you want to ramp up your hashrate, it would be better to go for an 'entry level' miner like an antminer S1, S3, or prospero X1. It'll cost the same for a much higher speed, you can get an S3+ (450GH) for about 0.4btc, or an S1 (180GH) for nearly free.

I want to know that I have not been able to get them to work in cgminer for some reason.

Here is the driver I use in case it is different than the one you have.
http://www.lpcware.com/system/files/lpcopen_examples_windows_usb_drivers_v1_10_0.zip
It works great.  What you do is you put in the COM port address of each Nano that way it picks them up.
Let me know if it help.

Here is the Bat file setup I use.

bfgminer.exe ^
-S ICA:\\.\COM66 -S ICA:\\.\COM67 -S ICA:\\.\COM72 ^
-o stratum.btcguild.com:3333 -O UserName:Password ^
--set-device ICA:baud=115200 ^
--set-device ICA:reopen=timeout ^
--set-device ICA:work_division=1 ^
--set-device ICA:fpga_count=1 ^
--set-device ICA:probe_timeout=100 ^
--set-device ICA:timing=0.22 ^
--api-listen ^
