No luck here, so far, getting the BabyJet to hash with 3.11.
Getting a "Hashfast detect (6:3) failed to initialize (incorrect device?)" message.
Update: It hashes using the PC build of 3.11. Is this a driver or permissions issue?
Yes, it is a driver issue. Without knowing more about your particular setup, just copy/paste this into Terminal before you launch cgminer 3.11.0 and it will disable all the known present conflicting drivers:
sudo kextunload -b com.silabs.driver.CP210xVCPDriver; sudo kextunload -b com.silabs.driver.CP210xVCPDriver64; sudo kextunload -b com.FTDI.driver.FTDIUSBSerialDriver; sudo kextunload -b com.apple.driver.AppleUSBCDC; sudo kextunload -b com.apple.driver.AppleUSBCDCACMData; sudo kextunload -b com.apple.driver.AppleUSBCDCACMControl; sudo kextunload /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/AppleUSBFTDI.kext
It may give a few errors but it's not a problem, it'll just complain that some of the drivers you tried to disable aren't installed (which we know), but others likely are installed.
The above is also temporary. Either logout and in again, or restart your machine, or replace every "kextunload" with "kextload" and run it again. Any of those will put your drivers back to how they were.
