Queer thing with my Huawei E1550 dongle: upcomes good, dialups with small lag, but
every second (even if not in connection) spams the message log with
Code: Select all
user.err kernel: option: option_instat_callback: error -71

They wrote:
A reason of their problem was:..."option: option_instat_callback:
> error -71" which apparently indicates a low-level USB problem...
Please, give some hint how to get rid of that spam, as it causes such unstability... Maybe patch "option.c" to disable error reporting in:The Marvell SoC doesn't support isochronous transfers usually needed for USB sound cards. USB 2.0 doesn't have isochronous transfer at all and thus some devices work and some don't. Being an unreliable data transfer method, it is used only for devices that can cope with missing chunks of data, thus USB storage devices never use it.
Code: Select all
line 837: err("%s: error %d", __func__, status);
Thanks in advance!
