Well, I spoke too soon. I checked the exact patched version of 3.12.13
kernel I run and that already has the 1199:9051 added to the list. So back
to square one -
1. 1199:9051 is present in the list with 3.12.13 kernel (patched to add
that in)
2. was working fine before the latest firmware upgrade
3. upgraded to latest and stopped working
4. Tried the suggestions here about using the 802-3 option in qmicli, no
luck there either
So if anyone else volunteers to upgrade to the latest firmware to see if
that fails too ;), that would be welcome :)
Rgds,
Gopa.
