------------------------+-----------------------------------------
Comment (by anonymous):
after i investigated more devices with SVN 41055 i figured out a "hardware
issue" between WR710nV1.1 and WR710nV1.2 !
I tested 5 devices v1.2 (green led) and 2 devices v1.1 (blue led)
And the result is reproduceable on ALL devices:
the v1.2 hardware works always perfect with directly attached LTE-stick
the v1.1 hardware never works WITHOUT an extra attached passive USB 2.0
Hub!
I opened up booth devices and check for different hardware, the
flash/ram/cpu
is exactly the same: AR9331-AL3A (Taiwan) - so the cpu is 100% the same!
But i figured out, that the usb-connectors "feeding" is a little bit
changed
with extra condensors and a few SMD parts are replaced/changed?
So my conclusion is: There is NO Power-Problem on the v1.1 Model, because
with an extra hub in the middle, this combination consumes more power as
without -
but it works this way!
With the older v1.1 model, there is a timing issue, as this results from
the "different"
d+/d- coupling/pulldown/pullup, or something else.
So i think it make sense the timing in the ehci-driver to modify and be
more relaxed
after a "power" on - There is still the same "streaming" problem as before
with SVN < 40842.
Playing with the "gpio8 0/1" trick to switch off usb power works after a
coldboot,
but it is far from perfect, because it´s not always working.
This is the result from a v1.1 without passive hub:
