Re: 3.14.12 and USB option_instat_callback with 3G DONGLE

Hi,
I am not familiar with git or code writting, I have no idea where to start. I was reporting the issue so hopefully someone with a clue who had one of these dongles might look to see if they experience this and know how to resolve it, if I cant figure it out, might have to go back to 3.12, since this logging in almost every 15 seconds (used for polling on incoming SMS's), but if I can help in some way i will try, but be warned, it would be like putting a 4yo in charge of a jumbo jet haha


Please CC direct any replies.

The device still works, it sends and receives SMS's as well,
I tried setting verbose usb debug to see if it offers any more explanations,
but it shows nothing more.

The device is Huawei E160, but is identified as (and always has been) an
E620

ID 12d1:1001 Huawei Technologies Co., Ltd. E620 USB Modem

Did somthing break between 3.12 and 3.14? Rather annoying at how fast and
large kernel.log is geting.

Any chance you can use 'git bisect' to try to find the problem commit in
the kernel tree?

thanks,
