hi forum - the win7-drivers required for the smartcard (= simcard) in the vgn p11z should be contained in the 'option' connection prog 'globetrotter.exe'. indeed 9 of them are thus rightly installed, but the last for the smartcard itself was permanently missed, and so globetrotter didn't find the device. I'd spend several hours on this problem. only by accident I found the solution:

open device manager < smartcards < actualize drivers < looking for drivers on the computer < NOT your downloaded drivers, but the LIST of companies provided by microsoft < sony < there are two drivers; choose 'identifiing device [so might be the english notification](NIST SP 800-73 [PIV])'. if you click it, the install message warns 'not recommended'. but when I had installed it the connection to the smartcard was at once accomplished (of course you must additionally insert APN, user name, password). - well, have fun - wadiwa
