Hello:
      Fan don't pwm adj.

Well I have actually been able to get the U3 to run under windows, so far the best I have been able to get is 43 GH/s and it still randomly Zombies after a few hours (it will always do it if the computer is set to sleep, turn off sleep settings and USB suspend and it runs for a few hours at least).
If anyone else gets the LIBUSB error flash before the device Zombie's out and gives device not found error, here is how I fixed that.
Note: I strongly suggest you make a backup of drivers, create a system restore point and a full system backup before attempting !

First delete ALL USB devices AND Drivers in your system. (If you don't know how to do this either look it up or move your miner to a different machine or get help)
Then reinstall all USB devices and drivrs from scratch. Then install silabs driver, then install win driver using Zadig. Restart machine then plug in U3, start bitmain cgminer version.
I have best results so far using 0755 for voltage  0982 for freq and 0.9 for baud.  Those settings give me a typical early rate of 50 GH/s that slows as it runs to average about 43 GH/s over a few hours.
Now I have yet to find any way to run two of these on the same computer, just won't seem to let second one run under same instance of cgminer and trying two instances creates system resource conflict with these.
As for a working Rpi image, well no luck yet, it should be a pretty simple matter to create one if driver is integrated into main cg fork.


To Kolivas (e.g. CrazyGuy) Thanks for taking on this project of integrating the driver for us


EDIT:
I am now using settings of 0795 for voltage  1306 for freq and 0.9 for baud.   This is giving me a pretty consistent 53 GH/s (although it still Zombies out after 8 or 9 hours for some reason that I have yet to figure out).
I am not going any higher with voltage since I don't want to start a fire. Will still be playing with drivers, freq and buad settings to try to find the best combo for GH/s  to error rate.

If anyone gets a working Rpi image please let us know. Maybe we can figure out a way to upload it and post a link so others can use it.

My thoughts exactly, yxt

I'm not running these miners,but I used these cables to run the little Gridseeds.



You can buy em from Cablez ,you should be able to run at least 3 U3's.

Just don't exceed 200 watts or so & you should be fine  

He might make em with just 3 barrel connectors,if you ask him nicely 

Yes to molexes, or PCI-E cables.

[I asked them to contact you to fix pimp the driver about a day ago, before you posted]

OK, it settled down but not as I was hoping.  It did run in the high 50's for a few minutes then started to hash lower and lower and lower rates.  Still getting lots of hardware errors and the power brick is hotter than the device.  Since it is now hashing in the 30 GH/s range, I switched back the voltage & frequency to 0755 and 0782 before my power brick melts too.  Back to getting 40 GH/s with no HW errors.

Is it possible to power the U3s from a Molex with the correct adapter?  I melted, a power supply last night running at bmsc-voltage 0780 --bmsc-freq 1306, which was as high as I could get w/o too many h/w errors

Is Bitman going to replace our burned out power supplies,

Guess that is kind of two questions

OK this seems to work, I'm getting high 50's GH/s, close enough to 60.  But it does kick out a bunch of "AMU: Invalid noonce - HW error" messages, at about the same rate as it solves hashes.  At lower voltage and frequency settings it gives no hardware errors but lower hashrate.  I've only been running it for 5 mins at this new frequency, so maybe it will settle down.  Should I worry about these hardware error messages or is this normal?


I tried that last night before I went to bed and it was still running this morning so it appears the zombie problem is solved.  I think I may have this thing working more or less properly now as long as the HW error notices are not an issue.

ok, can confirm!  hotplug U1 works with less speed.

can you comment on the fan speed and noise?

  Just get the U3 mined as usual,after it worked ,connect U1 to your Win7.Since the setting is not suitable for U1,both of the miners work,but U1`s hashrate is lower as indepdent,
about 930M/s.

currently trying new U3 since last week.
with the latest cgminer fork from bitmain's website it seems to work without zombie now.

But:
is there a way to have an U3 and U1 mining on the same Win7 machine? I know U1 is like a joke, but all this kinda below 1 TH is a game these days.

any way to monitor temp of u3 and adjust the very NOISY FAN?


this here is never ever at 25 db  (at 20 celsius room) more like 60-70 db.

About Zombie, don't set pc to sleep. Please offer screenshort when Zombie.

I sense a nice change in the air. They've contacted me offering me a U3 (after this message). While the value of one U3 is nowhere near enough to cover the development costs if I'd charged to merge and fix their driver, I've always been happy to do the same for existing drivers for when the manufacturer has freely offered it to me and will do so again here. Hopefully this means more official drivers in cgminer for bitmain products and hopefully they'll merge back our changes instead of maintaining their own various forks indefinitely.

  try voltage 0800 freq 1286 with --bmsc-options 115200:0.57
  about ZOMBIE issue,we have answer in another post #210
  

Please using U3 in Windos.

While I appreciate your attempt to help, the link you are offering is exactly what I have been using for days now and still can't get this thing to run for more than a few seconds before it Zombie's out.
I am running the miner under Windows 7 using the Bitmain cgminer version from that link. I have reinstalled all drivers multiple times. (which is why I am now trying to compile an Rpi image that works before I just give up and sell my U3's on ebay)

Hi,

Pls try to install USB driver again referring to manual https://www.bitmaintech.com/support.htm?pid=007201404130632574925y76a4v50657
Make sure you select CP2102   USB.   

We had supported here

--bmsc-freq 0D82 is setted at a large frequency. You shall modify '0D82' to '0982' which is the max frequency for U3.
