Since I installed Yosemite on my Mac, I cant connect my blumax GPS Mouse over USB anymore. The Terminal Tool dmesg says:
0 0 AppleUSBCDCACMData: start - createSerialStream failed
0 0 AppleUSBCDCECMData: start - Find CDC driver for ECM data interface failed
AppleUSBCDC: Version number - 4.2.2b5
Any suggestions? I think, I never had to install a driver, so this shouldn be the problem.
