Bitmain AntMiner U1 on Debian - not found

[j99]

Hello,

I am new to bitcoin mining and decided to give it a try using an AntMiner U1 on my Debian i386 box. I followed all the instructions and hints from this forum, installed cgminer from various git clones, also tried with bfgminer but it just won't work. AntMiner is OK because I also tested it on a windows machine and worked according to the instructions (reinstall driver etc.) but I can not make it work under Debian.

When I plug in antminer I get:

[12583524.528102] usb 2-2: new full speed USB device using ohci_hcd and address 2

but then when I start cgminer (or bfgminer) I am only receiving:
bmsc send golden nonce 
bmsc recv nonce timeout

And during this time my syslog logs these messages all the time:

etc...

What can be wrong? I tried many different cgminer and bfgminer versions with bmsc support and the problem is the same on all of them.. I run cgminer with following command:

cgminer --bmsc-options 115200:20 -o api.bitcoin.cz:8332 -u XXXXX -p XXXXX --bmsc-freq 0781

and bfgminer with:

bfgminer -S antminer:all -o api.bitcoin.cz:8332 -u XXXXXX -p XXXXXX

(the same commands work on windows laptop like a charm - except that I have linux box that is always on and want to use it)

Any clues? Thanx!

Make sure you have the newest version of bfgminer that supports the U1.

This works for meh.

Make sure you have the newest version of bfgminer that supports the U1.

like I said, I tried various different versions, including this one... it must be something else (maybe something with kernel) because it doesn't work on any version of cg/bfgminer

Hi,

I experience exact the same problem. I installed an Antminer U1 on my DreamPlug running on a Debian Squeeze system. The strange thing is, that it worked perfectly yesterday, but today there is now way it works. It keeps on disconnecting the miner. On my Debian I run CGminer, beause installing BFGminer gives an error. When running BFGminer on my Mac, everything works fine. Are there any solutions for this problem? Thanks!
