Funny you both mention shidehack and vh. I am running some old R808 and a few R606 in my shed. It is only thing I use cgminer at moment. I already tried using vh's fork of cgminer and is doing the same. I believe it is a problem with Raspbery Pi OS 64-bit when it has more than four sticks. I used my RPi with RetroPie installed as it was closest thing. I had no problem with it recognizing all the Antminer U2. It has been fun messing with these old stick miners. I held on to two of each stick miner I have ever used. But I think I just uncovered what might be a financial headache in the form of paper wallets. I used these to buy used GPUs 8-10 years ago.

I am not even sure if I am posting this in the correct place as I have no idea what actually is the problem.
I got my Antminer U2's out of storage to sell a few to a friend who was wanting to collect old asic miners. Out of the 11 I have only 4 show up as show up as ANU. The other 9 show up as AU3, which of course just throws errors. I am running cgminer 4.11.1 on Raspberry Pi 4.
I have changed usb hubs, deleted cgminer.conf, rebuilt cgminer and they still show up as AU3. I remember using --usb ICA:0 in the past to disable block erupters in the past. It has been so long since I have used these. I remember using --usb ICA:0 to run two instances of cgminer, one for Blue Furry and one with the antminers.
I know --usb AU3 does not work. Anyone know how I can keep them from being detected as U3?

@Something123 How many are you running per hub? I only have two 2Pacs each on its own Orico P10-U2-BK. When I build vthoang's cgminer with icarus enable and try to just run a single Antminer U2 I still get dead 2Pac. Using Minera on my Raspberry Pi results in dead 2Pac after about 24 hours. So I would have to set it up to restart before then or remember to restart manually, but would sometimes get 0 chips found on restart so I would still have to unplug the sticks.
So current stable setup: Raspberry Pi Model B Plus running Raspbian Buster Lite Version: September 2019 Release date: 2019-09-26 Kernel version:4.19 Adafruit 3.5" TFT display for the Pi 2x Orico P10-U2-BK each only running sing 2Pac @ Frequency 225 both with vpot set to 1.361v. No HW errors but I do get some rejects, but only like 100k rejects per 7mil accepted running @ combined 49.8 GH/s.
I am getting ready to try to enable icarus to try and run 10 Antminer U2 on a ORICO A3H10-U3-V2, but I have not had much success with --enable-gekko and --enable-icarus working well on Raspbery Pi. Because why not, I have them sitting around.
If I wasn't unemployed waiting on a decision about disability I would definitely get two Gekkoscience hubs along with 12 NewPacs. I would run my two 2pacs on each one of the hubs 2A port and NewPacs on the others.
[Edit] Yeah, I get weird detection issues. Even if I add the Antminer U2 after the 2Pac. It wants to treat one stick as U2 and the other nine as a single U3.

Well, I have been away for along time. My account got hacked about a year ago. I no longer had space to run my miners. I could never get 2Pac's to run with Minera without eventually running into rejects/errors or getting zombies after 24 hours. I also never did get them to play well with my Antminer U2's. A few years later I am unemployed with a little bit more free time(not much as a stay at home Dad). So success in getting them to run stable again(April 2017 I had them going 20 days without error.) If I just made a place to run the two 2Pac's two years ago, I might have mined enough to get a NewPac and hub. Lol

Thanks VH for the update. I have been up running for 19D 16H since I last did a git pull. Finally have some time to do pull updated code.

When I start cgminer, my rejected shares is at 2048 before I connect to pool.

My two sticks are probably at tail end of small orders.

Put the USB 3.0 hub into a non powered usb 2.0 hub. That is how I go my Orico A3H10 BK to work. Could not plug it into my powered Orico USB P10-U2-PK

Stencils arrived this morning so we got started on surface-mounting. By tomorrow I'll have about 600 sticks with ASICs mounted, and will have started on the topside components. All heatsinks are drilled and tapped and ready to be installed. Overall, we're right on schedule.
I also happened to fetch some materials to play with anodizing a bit if I get some spare time in the next couple days.
Awesome, can't wait. Sounds like a lot of fun to design and manufacture.

With BFGMiner and set-device, you can specify either the device path or device serial number, e.g. --set-device antminer@/dev/USB1:clock=ABC --set-device antminer@S1234567:clock=XYZ The issue with using the device path is it may change after a reboot. The problem with using the serial number is many hardware manufacturers still do not brand their devices. However, you can use the following tool to fairly easily add serial numbers and branding to cp210x devices: http://cp210x-program.sourceforge.netThanks update my .config file code above with antminer@COMXX:clock=x0123 seems to work for Windows. Same thing on reset the COM port might change since I inserted miners in different hubs at different times to get the order.

Is it possible to set each AntMiner U2 at different clock. I purchased some used ones. Two of the used U2 show there age and do not want to run at 2.0 but will run at 1.8 same with two older U1 they will only run at 1.6. If I try to set them anything else x0881 and x0781 respectively they hit about 30% hardware errors. I have tried the following config file but it seems to read and use the last antminer:clock=. { "pools" : [ { "url" : "stratum.bitcoin.cz:3333", "user" : "XXXXX", "pass" : "XXXXX", "pool-priority" : "0" }, { "url" : "stratum.btcguild.com:3333", "user" : "XXXXX", "pass" : "XXXXX", "pool-priority" : "1" } ] , "api-listen" : true, "api-mcast-port" : "4028", "api-port" : "4028", "expiry" : "120", "expiry-lp" : "3600", "failover-switch-delay" : "300", "log" : "20", "no-pool-disable" : true, "no-client-reconnect" : true, "no-show-processors" : true, "no-show-procs" : true, "no-unicode" : true, "queue" : "1", "quiet-work-updates" : true, "quiet-work-update" : true, "scan-time" : "60", "skip-security-checks" : "0", "submit-stale" : true, "temp-hysteresis" : "3", "shares" : 0, "kernel-path" : "C:\\Program Files\\BFGMiner\\/share/bfgminer", "scan" : [ "bigpic:COM6", "antminer:COM7", "antminer:COM8", "antminer:COM9", "antminer:COM10", "antminer:COM11", "antminer:COM12", "antminer:COM13", "antminer:COM14", "antminer:COM15", "antminer:COM16", "antminer:COM17", "antminer:COM18", "antminer:COM21", "erupter:COM19", "erupter:COM20" ], "set-device" : [ "antminer@COM7:clock=x0981", "antminer@COM8:clock=x0981", "antminer@COM9:clock=x0981", "antminer@COM10:clock=x0981", "antminer@COM11:clock=x0981", "antminer@COM12:clock=x0981", "antminer@COM13:clock=x0981", "antminer@COM14:clock=x0981", "antminer@COM15:clock=x0901", "antminer@COM16:clock=x0901", "antminer@COM17:clock=x0781", "antminer@COM18:clock=x0781", "antminer@COM21:clock=x0981" ], "api-allow" : "W:127.0.0.1" }

What is the size of heatsinks for chips on Antminer U2? I know thermal taped small heatsinks won't do much, but better than nothing (with good thermal tape). I am just having trouble searching for the size of chips and I can't find any sets for sale atm. Search Fail

I do love the sticks and would own another 10 or 20 of them if the price was good. 80-95 usd is a decent price
Agreed. Might buy one at $100 USD MAX. I would like to get a few, but think I might go with antminers $40-45 USD, maybe lower on larger buy.

Is there a way to continue OpenCL GPU mining while using remote desktop. I am using BFGMiner. Windows changes display adapter when in remote desktop causing my mining to stop. Is there a way to force it to use the GPU hardware even tough Windows changes display adapters? Other mining software that will allow me to do so?
