modprobe ftdi_sio - nonfunctional for (some) devices

[Hannu E K N]

$ cat /proc/version_signature
Ubuntu 4.2.0-27.32~14.04.1-generic 4.2.8-ckt1

Some background:

I have recently acquired a Flashforge Creator Pro 2016, a FDM/FFF 3D-printer that came with the [Open source "Sailfish" firmware][1].

Now to use the advanced features of the firmware you need to use "[ReplicatorG][2]" (free software) and connect to the printer using the provided USB-cable.

This relies on FTDI-based communications with it's ATMega 2560 -based controller board (Mightyboard 2560)

I can currently run Windows in a virtual machine (Virtualbox) and use ReplicatorG for the full set of features, including firmware updates (did that yesterday).

BUT, this is not possible using Ubuntu (14.04.4 and 16.04 installed and used in attempts)

From what I can see I should use
<pre>
sudo modprobe ftdi-sio
sudo chmod 666 /sys/bus/usb-serial/drivers/ftdi_sio/new_id
sudo echo "23c1 d314" > /sys/bus/usb-serial/drivers/ftdi_sio/new_id
</pre>
... then simply connect the cable.

This DOES set up /dev/ttyUSB0 and /dev/ttyUSB1 as expected, but these are nonfunctional

What I see is this, in dmesg

Now, this failure seems to fairly general, in googling I have come across a number of devices with very similar (if not the same) failure on all of them.

So it seems to be some sort of shortcoming of the `ftdi_sio` module.

HELP!?

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1595656

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Joseph Salisbury (jsalisbury)]

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

linux-image-extra-3.13.0-24-generic ==> and all versions after it? Probably a few before it too.
It sure exists in the current 4.4 too (current for Ubuntu 16.04)

[Hannu E K N (hannu-n)]

Is there a VERY hands on guide on how to install the very latest kernel?

I know this is a question about installing .deb packages...
But which ones do I need? amd64 for sure, but there are several to choose from.
And how do I install them in a manner that makes then easily removable?

I'm sorry, but I'm not ready to gobble through pages of text to accomplish this.

[Hannu E K N (hannu-n)]

May I suggest that any mention of the link in #3 (above) be presented, like this.

I get no entry for 4.7 in the grub boot menu.

All attempts to get to 4.7 was done on 16.04.

End of tries for now.
I have other things to do.
