How many USB Device on a single system ?

[squall1066]

I would like to nail a common miss-conception here about processors/memory/speed.

I have had 54 units on 3 hubs running on a p4 2.8Ghz (skt 775) with 2x512 MB memory (DDR2) on PCLINUXOS with a 20GB IDE drive.

All is sweet, CPU hangs around 2-3% usage, I have no idea why people are throwing money at "I" core systems with vasts amount of memory and HDD space.

If it a stand alone miner and you leave it as such, You can use dated hardware and save $$$

All on Intel Nuc Core i3

That is OSX.. lets see the 'activity monitor' and a double click on the "CPU usage"

I'm thinking I can get atleast 100 on a machine easily.  I just need a usb hub that supports that.  There are a few out there, but it's pricy.  better to buy some smaller and just daisy chain it.

Really?? The screenshot is of OSX, but he's blatantly using TeamViewer to remote into a Windows8 machine that's running 8 instances of CGMiner 3.1.1 to run 76 devices. And that Intel NUC is a 4"x4" little box with a dual-core 1.8GHz CPU. Not exactly beefy.

I know what you mean, my 'rig' has a single 4GB stick of DDR3, and a old i3 530 with one core disable and the other down-clocked to 1.3GHz and 1.05v! Doesn't even need a fan on it and stays around 50*C!

Sorry I imbued him with a little too much intelligence....

Seems you can get osx running on that intel stack.... with a few hacks, I initially thought he had gone that route.


Anyway .... whilst we are on the number of USB devices

Spotted another serious flaw with trying to 'tree up' a USB port to its maximum.. (actually it was my cat that found it)
A defective plug on a USB cable, allowed the cable to operate out of spec and in doing so took down a section of my miner network
(fortunately i'm on multiple controllers)... unfortunately it also burned out an ATX PSU

So maybe that is an argument for multiple cheap computers....
