Same behaviour with:
3.19.0-031900.201502091451 i386/32bit.

Both adapters are enabled if the hardware switch is on, once it's off
the network manager menu says that "Wireless networks are disabled by
hardware switch".  If I plug out the USB and plug it in it is still not
recognized.

Title:
  Lenovo S10e: no USB wireless lan hardware recognized if internal
  wireless is disabled via hardware switch

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  After having reported problems with my S10e's WLAN I bought an USB
  WLAN dongle, that works fine.

  But it only works if the hardware switch for WLAN is enabled - thus at
  the moment the internal WLAN interface and the external need to be on
  to make it work. Unfortunately (as reported in bug 1385059) this means
  that the internal interface is sucking up my battery when it tries to
  connect without success.

  My expected behaviour would be to disable the internal WLAN via
  hardware switch and be able to plugin my USB WLAN dongle.

  I've attached lsmod-output with WLAN enabled (USB dongle working
  perfectly, while internal WLAN hardware is constantly scanning for
  networks) and after disabling the internal WLAN.
