Hi,
I tried to plug my reader to my 64bit Windows 7 PC for the first time, in order to feed it with Calibre. But the reader was not recognized as a device. I don't remember the exact error message but it said that there is no driver available.
Right now I'm using an SD card as workaround which is ok for reading but not for my ego

Well, giving up on finding out myself is not better for the ego but it is much nicer to communicate in the forum with a chance for a solution. However, sending the reader to Sony for a firmware update is not an option for me.
Thanks,
hansl
