>Here is the recaptured log.

The log contains the following problem:

  [brltty] USB: claiming interface: 0
  [brltty] USB interface in use: 0 (usbfs)
  [brltty] possible cause: another brltty process may be accessing the same 
device
  [brltty] possible cause: the device may be attached to a virtual machine 
running on this host
  [brltty] USB interface claim error 16: Устройство или ресурс занято

I think the most likely cause is the first sugestion, i.e. that another 
instance of brltty is already accessing the same device. This is perhaps 
because it's being immediately started via a udev rule as soon as you connect 
the device.

I'm sorry if I've forgotten some details but I need to refresh my understanding 
of your problem. Is it that this (probably) udev-started instance of brltty 
isn't working?
