That's correct, in order for ADE to requires device drivers to recognize any of the Sony Readers. These device drivers are installed with the Sony Reader Library software. Note: this is Windows only, on Mac ADE cannot see the Sony Readers at all.
Thanks for the info.
It seems a shame to have to have both ADE library software and Sony Reader
library software in order to get DRM protected files on my PRS-350 reader.
Your help is appreciated.
It may be useful to mention this (the need to install the Sony library software and the no-function on Mac) in the help for moving books from ADE to supported e-readers (the PRS-350 is on the list of supported devices), since it clearly states that ADE will recognize e-readers when you connect them to an authorized PC and will prompt you to authorize the ereader. I have been trying for two days to get it to work and authorize my e-reader...
Grateul for your post, though, so I can stop my attempts.
