Bug Description
Using calibre 5.3 (also happens in 5.2, not tested in other 5.x versions), when connecting my old Sony PRS-T1 Reader, an error dialog appears indicating "Communication error with the device" (In spanish: "Error en la comunicación con el dispositivo") with the following stack trace:
calibre, version 5.3.0
ERROR: Error: Error en la comunicación con el dispositivo
'>' not supported between instances of 'NoneType' and 'NoneType'
Traceback (most recent call last):

TypeError: '>' not supported between instances of 'NoneType' and 'NoneType'
The steps to reproduce are simple: Just open Calibre, connect the PRS-T1 by usb, and the error appears few seconds after (I suppose Calibre is getting the reader contents, and fails here).
I get this error in this platform:
- PC: Windows 10 64 bit
- E-Reader: Sony PRS-T1
- Calibre version: 5.3 (Windows 64-bit). I get the same error in 5.2 (not tested in other 5.x versions)
WORKAROUND:
calibre 4.23 64-bit is working fine. Meanwhile I've uninstalled 5.3, and returned to 4.23
Let me know if you need more data from my side.
