Hi list,
I'm trying to get an USB-modem running on a Smileplug, which is some
Arm7-device, using it with the kernel 3.12-6. As far as I can tell
it's an USB3-port. It works well with harddisks, but when I plug in
USB-modems, it always fails sooner or later.
Is there anything that I can do to track down the bug? I attach the
syslog (journal - it's archlinux) when I plug in the modem, start
pppd, then try to do a ping. Sometimes some succeed, but very fast it
fails.
I compiled the kernel using usb-debug option, but I'm at a loss to
turn it on. I don't get any more messages than without that option.
Thanks for any help,
Linus
PS: flame me if you don't like log-files in attachements - I just
thought it's more readable...
This is a dongle ( Huawei E3131-s2 ?) with both ncm direct ethernet
interface and serial ppp interface, don't load the cdc_ncm driver if you
use it in serial ppp mode.
I've seen the same callback error and dongle firmware crash in the past
when both protocols are active.
