Topic: [Not in Stock - Free Shipping] AntMiner U1 USB STICKS - US/Canada .042 unit - page 25. (Read 47135 times)

Package arrived with the Antminer U1   havn't had time to connect it yet.


trying to locate my other ebay item lol it wasn't at the post office. I'm reaming them out on the phone now. with the tracking number


ran the zadig program, changed the driver and a single stick AMU is running on the Antminer forked cgminer
1.6Gh/s with the stock  --bmsc-options 115200:20 --bmsc-freq 0681

Hey iluvpcs

package is almost here, I have a lazy post office it seems, paid for first class delivery and all, and they left a stinking note to pickup at post office, or leave note in my LOCKED and SECURE mailbox (it also has LOCKED and  SECURE parcel boxes for which to place said package into, and leave a key with my regular LOCKED mailbox,) and they would delivery it on the 8th. pffft

so looks like I have to brave the frigid cold and go get it so I don't have to wait 2 days longer to play with the Antminer U1  

I'm so going to ream out the postmaster, my other ebay item wasn't signature requested. and they're holding it up as well. sheesh (they didn't hold up bulk rate mailings go figure) and they wonder why the USPS is going broke  

why can't I have the lady who drove on the guys lawn?  in the youtube video?  

I had one for my usb block erupters, could only get about 18 to work at a time.

Hmm I'm not sure if thats correct they have alot of vauge / conflicting data on that page. I've only used it for non powered stuff in the past. I'll plug in 28 antminers and see if they work.

Power Adapter
Input: 100 - 240 V, 50/60 Hz; 1.6A, maximum = 160 - 384 watts
Output: 5 V / 4 A = 20 Watts
Up to 500 mA power, all ports = 2.5 watts/port = 70 watts

That's the ugliest, but yet coolest, looking USB hub I've seen in ages.  Specs here: www.mondohub.com/hub_overview.php

only thing I'd caution, it looks like its powered with 4 AMPS at 5V, that is about 20 watts, or 9-10 of the AntMiner devices, any more and it won't be able to power them.

Your good,

I'm going to go visit a customer, be back online in afew hours.  See how bad this winter storm really is :/

3 ordered and payment sent 

This price is still good right?

Received my sticks. Spent two nights and finally got them to work on my Raspberry Pi. Thanks iluvpcs! Will definitely buy more from you if only I have more BTC.

The miner I bought arrived today.  It is *CUTE*.  It will make a nice addition to the collection.  It was a pleasure doing business with iluvpcs and positive trust was left.

The windows binary works just fine once the USB driver is installed.  Too bad for me I don't normally run a miner on the few windows machines I own.  I prefer to keep my miners on a raspberry pi.

Now for the bad news, and none of it has anything at all to do with the group buy.  What I received is exactly what is represented in this group buy.

First of all, the linux binary listed above does not run on any of my machines.

So, I pull the source code for the modified version of cgminer from https://github.com/bitmaintech/cgminer and the fun begins.

The first issue I find is a pretty big one.  The AntMiner U1 USB stick uses the same usb signature as an erupter.  This does not need to be an issue but as it is right now, it is not possible to compile cgminer to support BOTH an AntMiner U1 USB and and a block erupter usb with the same instance of cgminer.  Older versions of cgminer and bfgminer think it is a block erupter usb and does weird things with it.

Then, once configuring for the "bmsc" driver I run into some rather nasty compiler warnings.  one is true where the code copies 5 bytes into a 4 byte storage which immediately crashes the program.  The crash was disguised in a code update between yesterday and today as the device is no longer addressed so the broken code is never executed.  I will spend a bit more time playing with this later but right now it appears to be a windows only solution.

Ok, going back to the windows binary only release, the device is reported as "AMU", same as a block erupter USB.  Not nice.  It should have its own name.  Furthermore the stock "miner.php" script does not enumerate the AntMiner sticks.

So ... it is only a matter of software.  The stick I have is hashing at 1.55 Gh/s on windows xp running stock.  Now to overclock the sucka..

./cgminer --bmsc-options 115200:20 --bmsc-freq 0781 -u P2Pool -p P2Pool -o stratum+tcp://localhost:9332/ -D

I got mine yesterday, and all work perfectly!
