Kobo not recognized anymore

[ubartosz]

Hi All,
I hope that you can help me. I have two Kobo readers (Glo HD and Aura). Both used to work perfectly with Calibre, but since a few weeks they are not being recognized anymore.
I'm running Win 10 with Calibre ver. 2.49 and Kobo firmware ver. 3.16.576. Both readers are correctly recognized in Windows (drive letter assigned) and by the Kobo App.

Thanks!
Bart

There is an issue it seems with SOME PCs that have been upgraded to Windows 10; some times it seems Kindles and Kobos are not detected.

What is interesting though is that you say that Kobo Desktop DOES detect the device.

In a posting on a thread dealing with a similar issue on a Kindle, Kovid has supplied a command he'd like to see run on a machine with this issue.

Could you try this and post the result?

[ubartosz]

Hi Peter,
Thanks. Here is the result:
C:3 D:3 E:5 F:3 G:5 I:3 J:3 M:3 P:3 V:4 X:4 Z:4

I hope it tells you more than it does to me...

Regards,

[PeterT]

Which drive letter is your Kobo? In theory it should be type 2....

0 Unknown 
1 No Root Directory 
2 Removable Disk 
3 Local Disk 
4 Network Drive 
5 Compact Disc 
6 RAM Disk

[ubartosz]

Kobo is I:
And it's true - Windows shows it as a local disk... Do you know how do I change that?

As a possible workaround,
Use Connect to Folder (On the connect share Icon)

You need to set (if used) the Template to the same as you were using for the Kobo Device

I don't know what you do if you are using the Kobo Utilities PI

[PeterT]

See this post from Kovid. Download and see if it helps

[ubartosz]

"Connect to folder" workaround worked. At least I can manage books easily.
The beta build doesn't seem to solve the problem for me unfortunately...

Thanks!
Bart

[kovidgoyal]

If the beta is not working then post the output of the debug device detection button in Preferences->Miscellaneous from the beta, with your device connected.

Well, that tells me why it is not working, looks like I will have to try something else, since the device path of the volume id does not indicate it is mounted over USB

[ubartosz]

Great! Thanks for your help :-)

[kovidgoyal]

Next step, in a windows command prompt can you run the following and post the output (with your Kobo connected)

calibre-debug -c "from calibre.devices.winusb import *; print get_drive_letters_for_device(0x2237, 0x4203, debug=True)"

[ubartosz]

Here is the result:

Sorry wrong command, here is the correct version:

calibre-debug -c "from urllib import urlopen; exec urlopen('https://raw.githubusercontent.com/kovidgoyal/calibre/master/src/calibre/devices/winusb.py').read() in globals(); print get_drive_letters_for_device(0x2237, 0x4203, debug=True)"
