Comment(by erikos):

 Ok done some new testings:
 type: B4
 image: joyride 179 and 199
 firmware: Q2C27, updated to Q2C28

 As said both of my B4 machines have the WLAN stop working issue. When the
 WLAN stops working my usb-devices are not recognized anymore like
 described here and in #1752. They work before the problem occurs. I
 updated from firmware Q2C27 to Q2C28 as described in #1752 to fix the
 issue but the problem still occurs - with the WLAN stooping working and
 the usb devices not being recognized (like others described the mouse or
 keyboard does get recognized fine). I am not sure about the ECO status.
 Under the battery I only found B4-17 SHF250072C and the serial number. I
 turned libertas_debug on and attaches the output of two WLAN fails on
 different machines and one output of a usb-stick failing.

 I can confirm that iwpriv msh0 fwt_time will respond "Bad address". I
 remember testing this with Q2C27, have not done with the 28 but will test
 when the machine fails again - have to hurry up this will be soon :)
