I have a Toshiba notebok (Satellite A10-sp1001) working with Windows XP-SP2 and it has a Toshiba V.92 56Kbs internal modem. I installed a usb connection to use the cell phone as a modem and now the notebook doesn't detect the internal modem. I reinstalled the drivers (from the original disk) and downloading it from Toshiba's site with no success. Also, the manual says the modem port is COM3 however, the only available COM ports are 5 and 6 (actually only 6). How do I solve this problem?
