Calibre Companion connecting Kindle unit / computer
I have a Kindle Fire HD 7" unit. I use Calibre as an e-book management tool on all my computers and I employ the app Calibre Companion 3.6.10 (157) on my Kindle unit.
I can connect without problem to my main desktop computer running Windows 7 using the wireless option provided by my network. Sync works perfectly.
I tried unsuccessfully to connect to my old portable computer running VISTA Home Premium through the USB cable having selected Calibre Companion content server option since this computer does not offer a wireless option.
The "On Device" column opens up but it remains empty.
Any suggestions ?
