Keyboard freeze

[Şerban S.]

Hi!

I've been looking at the lines listed. I also had trouble (different causes, similar behaviour) related to some devices.
In my experience, the problem comes from your USB Controller. Namely, a certain device that is attached through the USB Hub you are using.
Watch closely the following lines.

Here's the latest log. I don't see anything. Let me know if you get any clue:

You can notice the number of errors on the attempts to access a device. I assume it is a storage media.
The polling USB routine attempts to reconfigure the bus but fails everytime.
Unfortunately, it is extremely difficult to figure out what really happens.
To make the long story short:
1. Remove any USB device attached to the system.
2. Plug in the USB devices one by one, in this exact order: USB Keyboard.
3. Start the computer.
4. Plug in the next USB devices, one by one: USB Hub; USB Mouse; USB Audio interface (if any); USB Printer. The last ones: USB Storage media.
5. At each step, write down on a paper IF something unexpected happens.

Please also do the following from the CLI:

Code:

sudo inxi -c 0 -ACdGMNSz

Post here the contents of the report.

Do also

Code:

sudo lsusb

Add the result to the post.


A little bit of digging, proves I got the trouble figured out correctly:
