Weird USB interactions?
by Tom Horsley
When I use my AVRISPmkII programmer to fool with the
microcode on my 3D printer motherboard, my mouse and
keyboard apparently get reset. All the settings I made
with xinput disappear and I have to re-apply them.
The ISP is running through the same powered hub as the
keyboard and mouse, maybe something is resetting more
of the USB tree than it should?
Should I report this as a kernel bug? Should I try to
find more information to gather? What is going on here?

3G dongle getting detected as USB disk on Fedora 18
by Soham Chakraborty
Afternoon folks,
I know that Fedora 18 is kinda obsolete but for a number of reasons, I have
to stick to it for the time being. However, I am quite sure that this
problem/behavior isn't restricted to F18. But since I am using that, ought
to say that.
So, here is the problem.
I have a ZTE K3800 dongle which I use for wireless/3G connection, provided
by Vodafone. When I plugin the device, it prompts to connect and works.
Problem is, as soon as I connect, systemd sends a signal 15 to
network-manager and the applet disappears from system tray. Therefore, if I
try to configure VPN, I find no option. Note that, I am only trying to
configure from the nm-applet.
lsusb shows me this

I checked in /lib/udev/rules.d/ to see whether I can find anything but not
much success.
BTW, this article gives some clues but I don't have the configPack.tar.gz
file to clone.

Any help will be appreciated. Also, if any other information is required,
do shout and I will provide.
Thanks,

blueman/bluez in F20
by Ranjan Maitra
Hi,
I have been using blueman intermittently (as needed) for the past few
Fedora distributions but now it appears that that has been obsoleted
for F20. I was wondering what the best way for getting this to work is?
Is there any resource where I can turn to for some help?
I tried bluetooth-wizard and got it to recognize (only) some bluetooth
devices but how do I get to connect to those after that was not at all
clear to me. There used to be something called blueman-manager or
something like that. Is there something equivalent to that?
Many thanks and best wishes,
Ranjan

Used fedup . What happened?
by dave peters
I attempted to upgrade from F19 to F20. I used a dvd of F20 (x64) and
ran:
fedup --device
All appeared to go as I would expect. However, uname now gives me:
Linux localhost.localdomain 3.12.5-200.fc19.x86_64 #1 SMP Tue Dec 17
22:21:14 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux.
What have I done? What should I do next? I can restore the previous F19
(I hope)
Thanks
