Calibre vs. Oasis 2 - Connectivity issues while sending docs

Bezuchow · 01-18-2018, 07:17 AM

I posted this in the Kindle section of the forum but I thought it might be a good idea to repost it here:

I have recently experienced strange connectivity problems while sending documents from macOS Calibre (v3.15) to Oasis 2 via USB. First, it seems to take ages to send a single mobi document (ca. 4MB). Second, during the sending process the device wakes up multiple times for a short while in order to return to the USB connection mode. During the process macOS Finder seems to have a problem with accessing Oasis's hard drive and tends to freeze. Sometimes Calibre freezes too and I need to force shutting it down. On the other hand if I wait patiently Calibre usually manages to transfer the doc after about 20 minutes.

I have never had such a problem with Paperwhite 3 or Kindle Keyboard.

Any advice will be much appreciated.

Thank you.

That's a hardware problem. Try a different usb cable/port if that does not work, reset the device.

Thank you, Kovid. Changing the cable solved the issue.

I have noticed that the cable provided with Oasis 2 works properly whereas my older cable (provided with Paperwhite) generates problems. On the hand, the Paperwhite cable seems to work fine with other devices.
