I discussed with the some guys. For me there was no explaination why the
USB-device is "disconnecting".
There could be one thing: The power consumption for this hardware is
higher than allowed by USB (two dib3000 and two MT2060 = 700mA, USB
500mA). But because it is a PCI card there is no problem, because the
USB-descriptor should state: Self-Powered.
If this is not the case, maybe the VIA-chip is disconnecting the device.
Can someone check if the lsusb -v output is showing something like:
bmAttributes 0xe0
Self Powered
Remote Wakeup
