yea i had that issue befor. I know its a PITA but I reformatted the HD and no issues since.

Can anyone with a similar rig comment on stability? How often do you need physical access to your rig, and why?
Software updates will bring more stability. Stay away from windows. I currently have 99 DMs running on a Pi for over 72 hours without any failures. I was having issues for a while where a DM or two would go down and I would have to have physical access to the hubs to fix the issue. After running only 9 DMs per orico p10-u2 and some new software (still testing, should be committed to git soon) I haven't had any fail. My only downtimes have been me moving pools. Once everything is configured properly you shouldn't need physical access often.
I got 18 right now on a 49 port hub. on a windows machine with NO downtime.

Hobby miner as well. I've been running 3 dualminers on Raspberry Pi and an Orico 10 port USB hub for a good 4 days now and getting the 70kh/s on all three miners these are my stats so far A:1224336 R:34896 HW:58. So haven't had any major issues. I did have to restart when I was using the miner on Windows 7.

Any experience if i use dualminer with the D-Link Hub H7 ?

I'm hobby miner. GPUs, Block Erupters, BlueFurys, Bitmine U1s and DualMiners. Thanks to LightningAsics sloooowwwwnes and nonresponsiviness I'm still waiting for 5-chip Gridseeds. I can only say that DualMiners are the reason installing CGWatcher for the first time. CGWatcher successfully replaces Dualminer GUI mining program that is not being capable to successfull restart miners. Because they need restarts too often to be manually restarted. I'm mining with Win7 x64 in scrypt-only mode, power supply is not the problem and from time to time some of them knows to disappear from list of COM ports under device manager. The only way to bring them back from nirvana is to disconnect/reconnect at USB hub. To summarize, they are worst units from my collection for unattended mining. Maybe next version of BFGminer is going to make them more reliable.
Also hobby miner here.
I'm currently running a PI with a couple little USB SHA-256 ASICs, and one DualMiner running LTC-mode only. I'm running the BFGMiner fork that just added DualMiner support. I find that the DualMiner dies maybe every 12-36 hours, and it requires me to re-start the scrypt window. This doesn't affect my SHA-256 mining at all. I believe everything is being powered appropriately and cooled. When it runs, it runs flawlessly. Looking right now, after 19 hours, I'm at 71.9 KH/s, no HW errors, and only 22 rejects to 4838 Accepteds.

I'm interested in building a mining rig with a Raspberry Pi and 10 (to start with) DualMiners to mine Litecoin. The guides on this thread are great. It looks like such a rig will be compact, scalable, greener (compared to GPUs) and easier to pull together and manage than other approaches.
Sure it will have a longer ROI than a more traditional GPU design, but I'm betting on the currency increasing in value (as we all are), and I want to have more fun than just currency speculation.
My best deployment options are to put the rig in a server closet or colo rack. So power and cooling are not a problem. Stability is my main concern.
Since I'd be running the rig headless in a different physical location, it's important that I not need to fiddle with the miners once they're up and running. Note that I'll have VPN access to the Raspberry Pi. And if need be, I can plug the USB hubs into a managed UPS that would allow me to power cycle them remotely.

I can only get 2 devices to show up in linux, anyone else having this problem?
I'm having a ton of problems in win 7. I think the usb hubs aren't up to snuff.
Anyone have a link to the recommended USB hub brand?
I only have two running on a hub but Orico 10 port USB 3.0 hub has been a trooper. $26 on Amazon and it is what the manufacturer suggests. Comes with an external power plug. I'm running Win 7 pro 64bit.
I thought the usb 3 was not good for them.
First I heard of it. Been mining away no problem. I actually have less issues with these than my bitcoin miners.

I found an Etekcity 10 port hub (that I had) that looks to be exactly the same as the Orico, just under a different label. I hooked my miners up to them and they have been rock-solid steady for almost 24 hours. Therefore, I think that using the right hubs is essential to these fellas.

They are trying to get rid of them

I finally got 5 up at the same time in linux but they would not stay running for more then 15-20 mins before causing disconnects. So back to windows they go. These either have more strict requirements the the outer usb miners I have used or are just not as stable. I think I am goin to wait until something else comes out before investing more money into scrypt chips.

Have you tried the tutorial on the USB setup at the DM site?
http://support.dualminer.com/?page_id=38
I got my two DM running fine from the get go on Rosewill 10 port usb hub, however I use win 8.1.

That is solid.
What are you pulling power wise with that setup?
