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
[12583524.744055] usb 2-2: New USB device found, idVendor=10c4, idProduct=ea60

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!
