Hi all,
Root cause is chinese Arduino board (ID 1a86:7523 QinHeng Electronics
HL-340 USB-Serial adapter). The board some
[1.] One line summary of the problem:
ch341 module fails on 4.1.1 kernel
[2.] Full description of the problem/report:
It's not possible to work with Arduino board after installing 4.1.1.

Sorry for misunderstanding, I've tested the behavior of Arduino board
on 2 machines and the result is following:
PASSED - Arduino board was connected successfully
FAILED - ch341 errors arose
1st machine [USB 3.0] -- Linux 3.18 -- PASSED
1st machine [USB 3.0] -- Linux 4.* -- FAILED
2nd machine [U
