Hello bmoscato,
cgminer 4.11.1 got this timebug.
First of all, It is not affecting your mining, just the date / time display is wrong.
If you compile cgminer by yourself, you can incoperate this pull request from
Victor Huang:
https://github.com/ckolivas/cgminer/pull/735and this is fixed.
Or, you use cgminer 4.10.0 where this bug does not existed.
With this version you will also have no trouble using the U1/U2 just make sure that your user
is in the plugdev group!
Quote from the Readme:
LINUX:
The short version:
sudo cp 01-cgminer.rules /etc/udev/rules.d/
The long version:
On linux, the direct USB support requires no drivers at all. However due to
permissions issues, you may not be able to mine directly on the devices as a
regular user without giving the user access to the device or by mining as
root (administrator). In order to give your regular user access, you can make
him a member of the plugdev group with the following commands:
sudo usermod -G plugdev -a `whoami`
If your distribution does not have the plugdev group you can create it with:
sudo groupadd plugdev
In order for the USB devices to instantly be owned by the plugdev group and
accessible by anyone from the plugdev group you can copy the file
"01-cgminer.rules" from the cgminer archive into the /etc/udev/rules.d
directory with the following command:
sudo cp 01-cgminer.rules /etc/udev/rules.d/
After this you can either manually restart udev and re-login, or more easily
just reboot.
