oo kazka radau, bet nelabai cia viska suprantu
I've encountered the same problem today with a DCA-540 cable. I managed to fix it by doing this: checked BIOS, enabled two COM ports, made sure there are no conflicts, installed MPM for CX65, extracted the DCA-540 drivers somewhere. Then I rebooted, removed the "siemens mobile phone usb modem", unplugged and plugged the cable again. It found new hardware, installed the driver "siemens mobile phone usb modem" again but this time correctly. Now it works.
