Known Firmware Issues The current firmware has two known bugs that limit the usage - of the device.

There is a problem with the enumeration on USB 3.0 + controllers and the second is related to enumeration on OS X (Lion). + The firmware does not properly enumerate on systems with USB 3.0 controllers. The issue has not been analyzed and the workaround is to use a USB < 3.0 port or put a USB < 3.0 hub between. - The firmware has issues with selecting the right baudrate of - some SIMcards. The microcontroller will call the parity error interrupt - handler and the watchdog will reset the device.
