Title: cgminer Antminer U2 device not seen Post by: strombert on March 27, 2014, 01:15:04 PM Hello everybody,
I can't get my new antminers U2 to work, never done mining before. The devices can not be seen ! I have the winusb drivers with ZADIC ready, but I don't know what to do with the CP210x_VCP driver, I think they are just for bfgminer. Also the bat-file is a problem. I only find command-lines for the old U1, not for the U2. Have 2 of these here, wanted to try DEM (eMark) for fun, it's hard. Anybody willing to help out? That would be great !

Search for "GETTING STARTED WITH USB ASICS" in the windows section. Cgminer works fine with these devices.I can't get my new antminers U2 to work, never done mining before.

The old U1 and U2 are ( software ) identical so just follow the steps as if it was a U1 to get it going. In the bat file don't forget the path TO where you unzipped your mining software. I tend to use BFGMiner for AntMiners and Erupters as it tends to be more stable on my PC. Code: cd Programs/BFGMINER Make sure you have enough power on your USB lines for the miners. Plugging directly in the back of a PC may have enough power, I've got 3xU1 and 4XErupters and had to install 2 of them ( one of each ) on a front pannel mount connected inside the case ( with an L bracket to keep it from sliding around, does not show outside except the odd flash for finding shares ). The biggest issue is the power needed and with the ' correct ' settings for overclocking. With out actually adding the 10k SMD 0603 resistor the highest clock value should be 0981 ( 2.0 GHash/sec )and without it, it should default to 0681 ( 1.59 GHash/sec ). I purchased an external USB hub, cut the 5v line in it and use a power adapter that was for an old wireless router ( 5v@2.5A regulated internaly ) and can have 2 Ants and 3 Erupters with this setup and just have to unplug it when restarting the PC just to be safe. |
