What does it use? I know it recommends you download Zadig. I have it, but I can't seem to reinstall with it. What is the procedure for reinstall?
This is from an older ASIC Readme. Just substitute BFL with Block Erupter/AMU and you should be good to go.
WINDOWS:
On windows, the direct USB support requires the installation of a WinUSB
driver (NOT the ftdi_sio driver), and attach it to the Butterfly labs device.
The easiest way to do this is to use the zadig utility which will install the
drivers for you and then once you plug in your device you can choose the
"list all devices" from the "option" menu and you should be able to see the
device as something like: "BitFORCE SHA256 SC". Choose the install or replace
driver option and select WinUSB. You can either google for zadig or download
it from the cgminer directory in the DOWNLOADS link above.
When you first switch a device over to WinUSB with zadig and it shows that
correctly on the left of the zadig window, but it still gives permission
errors, you may need to unplug the USB miner and then plug it back in. Some
users may need to reboot at this point.
