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

[HugoHirsch]

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.

Output of lspci -vnvn with both WLAN devices enabled and one working fine.

I ran the apport-collect after disabling and enabling the internal WLAN. An output of lsmod for both states can be found in the attached txt-files.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.19 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

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.
