Situation:
I use two copies of Calibre library, on Windows 7 and OS X, synced by dropbox.
I use Pocketbook 650, connected to Calibre using "user defined usb driver"
Everything works fine, except one annoying problem:
When I connect pocketbook to Calibre on Mac, the usb driver thinks what the proper folder on device is "my books"
When I connect device to Windows - Calibre uses "books" as default folder.
I tried to enter the folder names in all possible ways in driver config field - "My Books", /my books, \my books, etc - Calibre just ignores it and keep looking for books in "books" on Windows and in "my books" on Mac.
Thank you to any ideas!
