#1771 A10-70F doesn't show on Fedora 27

[Todd Chester]

Hi All,

Fedora 27, x64
libmtp-1.1.14-1.fc27.x86_64
libmtp-examples-1.1.14-1.fc27.x86_64

My Wife's Android
Lenovo: A10-70F
Android 5.0.1
does not show as an MTP device. It does as a CDROM. And it does show up on the same machine on qemu-kvm Windows 7.

I reported the issue over on: https://bugzilla.redhat.com/show_bug.cgi?id=1527735

libmtp-examples-1.1.14-1
mtp-detect std err: Device 0 (VID=17ef and PID=789a) is a Lenovo A10-70F.

/var/log/messages:

has this been fixed in "upstream"? If so, is there a workaround to get Fedora 27 to see it?

Many thanks,

usally some magic needs to be done so it swirches to MTP.

buit could you check on-device in the USB access menu if it cannot be just switched to MTP mode?

Hi Marcus,

I have tried all the modes you see on
https://bugzilla.redhat.com/attachment.cgi?id=1410191

The top one, which is MTP and is the defualt, does not work, but does work when passed through qemu-kvm to my Windows 7 virtual machine. It also use to work on Scientific Linux 7.4 (RHEL clone) before I upgraded to Fedora 26. (That is an odd one, as usually things that do not work on RHEL and fixed in Fedora.)

I now am on Fedora 28 and the problem presists. The mode (forth down) called "Built-in CD-ROM" does work, but only gives a couple of useless files. I have tried all the modes you see in the link. No joy.

This is under Fedora 28:
$ mtp-detect | grep -i a10
Device 0 (VID=17ef and PID=789a) is a Lenovo A10-70F.
Lenovo: A10-70F (17ef:789a) @ bus 1, dev 7
Product: A10-70F
Model: Lenovo TAB 2 A10-70F
ba10: WPL Playlist
Friendly name: Lenovo TAB 2 A10-70F
Synchronization partner: Lenovo TAB 2 A10-70F

Is there any test you would like me to run?

Many thanks,
