Hi,
just received my Leafe2 and when launching Calibre, getting the error below any help appreciated:

I noticed that the USB interface descriptor for MTP on my Poke3 is weird.
I patch it in my kernel. I have no idea if that will make any difference, I doubt it.

C:\>kpatch payload rec.sym onyx.kpc MTP
Profile #8: MTP
01fbfd50 mtp_interface_desc
01fbfd50 09 (ok)
01fbfd51 04 (ok)
01fbfd52 00 (ok)
01fbfd53 00 (ok)
01fbfd54 03 (ok)
01fbfd55 ff -> 06
01fbfd56 ff -> 01
01fbfd57 00 -> 01
01fbfd58 00 (ok)

(This is actually showing patching the recovery on a Leaf2.)
It's probably either a communication glitch from a wonky cable or a bad MTP driver in Windows.
In the interim, you might look into my AdbSync.
I use that to synchronize books onto my devices.
