Mine is a black 1.4 revision Kobo from Borders Australia, but I have used 3 different USB cables with it, I don't even remember which one came with the device.
Today everything is working well, managed to get all my books loaded via Calibre with no errors. This makes me feel more like the USB port is dodgy, I'm gonna have to run some more tests on it, if it is a bad USB port I want to make sure I get the device replaced before the warranty runs out.
Anyone had any experiences with returning a Kobo to Borders Australia? Do they just swap the thing or will they want to send it off to Canada for repair?
