5.0 out of 5 starsWorks great with BFGMiner on Windows 7 Pro SP1 64bit.

on June 9, 2015

Setting up the Avalon Nano 3 was moderately annoying, however after a bit of persistence I was able to get it running on Windows 7 64bit SP1 Professional.Downloading the file from their website and running it will install the program but the program didn't work for me. It also installed a driver, which was probably 32bit and my system is 64bit, but that didn't work on my system either. When I went to run the Avalon GUI it did nothing. I stopped the Windows Service it installed. The GUI and "bfgminer.exe" were stuck in Task Manager and I had to kill them manually.If you go into Device Manager you will see that when the Avalon Nano 3 is plugged in you have an unknown device under "Other devices." This is probably why the GUI hung and why the command line miner didn't work at first. To resolve this issue, find and download the "LPC USB VCom Port" driver for your OS. This creates an interface that emulates a standard serial device. The driver set itself for COM3 but you can modify that if you want. Make sure to set the Bits per second of the virtual port to 115200, Data bits at 8, no Parity, Stop bits at 1, and no Flow control. You should now be able to run the GUI without issue provided that you stopped the Avalon service, killed bfgminer, and killed the AvalonGUI program.Looking under the "C:\Program Files (x86)\Avalon Nano\" directory you will see an install of BFGMiner. If you run the GUI, which should work now that the proper driver is installed, you will see a file called "icadbg.cmd" in that directory. It is a plain text file and may help point you in the right direction but I had to do some research to figure out the right command to use. The same information can be found in "C:\Program Files (x86)\Avalon Nano\AvalonGUI" in a file called "avalon.ini." You will note that this file and the "icadbg.cmd" files both point to the same server with the same username and configuration but the "avalon.ini" file has three servers it points to which map to the GUI. I might suggest that you make backups of those files and then edit them accordingly. You can also override the settings in the "avalon.ini" file through the GUI.This is what works for me on the command line with the version of BFGMiner that is installed with the Avalon Installer. The site bitminter does not require a password which is why that option does not exist in my command line below.bfgminer.exe -o stratum+tcp:// -O myusernamehere -S ICA:\\.\COM3 --set-device ICA:baud=115200 --set-device ICA:timing=0.22 --set-device ICA:reopen=timeout --set-device ICA:work_division=1 --set-device ICA:probe_timeout=100 --set-device ICA:asic_count=10 --set ICA:clock=450 --set ICA:voltage=0.6625 --set ICA:fan=95The text file documentation in the BFGMiner directory should hopefully be sufficient to answer most additional questions. If you look long enough and hard enough across the Internet you may find information on the reasoning for the configuration above.All tolled this took me about two man hours to figure out how to get this device to work, modify task manager to launch BFGMiner at logon, and disable the Avalon Service. Sadly the latest version of BFGMiner (5.2.0 as of this writing) isn't showing me any love right now, but now that my device is working that is a task for another day.

I am not considering making another purchase of this product right now, but if I do I'll be getting a powered USB hub as space on the back of my PC is limited.
