No MBED device on Mac

Hi,

I got one of the new Arch Pro boards connected to my Mac. Using the USB Port next to the ethernet socket I'll get a Arch Pro storage device of 2k capacity with a HTML file. On the second USB port which should be for programming with bins, I don't get the expected MBED storage.

According to syslog, the device is found but times out:

USBMSC Identifier (non-unique): 90040200E48DC4231972ABDF 0xd28 0x204 0x100, 1
USBF: 170635.871 AppleUSBEHCI::Found a transaction which hasn't moved in 5000 milliseconds on bus 0xfa, timing out! (Addr: 6, EP: 0)
USBF: 170646.880 AppleUSBEHCI::Found a transaction past the completion deadline on bus 0xfa, timing out! (Addr: 6, EP: 2)

after that the message:
USBF: 170711.923 AppleUSBEHCI::Found a transaction which hasn't moved in 5000 milliseconds on bus 0xfa, timing out! (Addr: 0, EP: 0)
is repeating constantly

The device can be also found in System Profiler as an MBED CMSIS-DAP device ... anybody got an idea?
