These errors happen after disconnection, and they don't last long ( i think)
, i have only few lines of them every time i have problem with internet.
This is old PIII 450Mhz, on EPOX motherboard, so there are only two usb
ports at the back. Modem has problems on both of them. I think there are
additional two on motherboard, but i do not have external usb ports and i
can't use them.
The biggest problem is that only reboot of system helps for this situation.
I can't unload usbatm module, even after unloading speedtch and uhci_hcd
first. Killing all pppd doesn't help either. Module is busy, and when i use
force option, i get error that module is temporarily unavailible. The same
is for usbcore. And i have to reboot computer, because ppp hangs up.
Do you think that PCI usb controller, or maybe newer speedtouch revision
will help? ( have 2.00 currently).

Hi,
I have serious problem with my SpeedTouch 330 modem. Lately i have
changed
motherboard in my home router. Since then i get random disconnections.
Sometimes my connection
last for 10 hours, somethimes 20,and it maybe 1 hour as well. After
disconnection i can't reconnect it until i reboot my server. First of
all
there is no way to unload USBATM module. It just stucks.
you need to unload the speedtch module.
And when i
re-synchronize modem and try to use PPPD CALL SPEEDTCH again, it tires
to
connect and gives up after some time.
The previous pppd may still be running - try killing it first. If that
doesn't help, send in the contents of the file(s) /proc/net/atm/speed*
I really don't know how to hande
this problem. My isp is using PPPoE. Here are my logs that i thought
maybe
useful in this case:
...
Nov 2 22:24:16 szymon firmware_helper[9799]: main: error loading
'/lib/firmware/speedtch-2.bin.2.00' for device '/class/firmware/1-1:1.0'
with driver 'spee$
- BUT FIRMWARE IS LOADED ANYWAY AFTER THESE ERRORs. So i really don't
know
what is his problem. Next:
The driver tries to look for different firmware files based in the modem's
revision (notice how the suffix changes). Some distributions make the
generic firmware loading mechanism complain if a firmware file isn't found
(I don't know why - surely it is up to the driver to complain if it is
unhappy?) and it seems like yours is one of these. Ignore these errors.

This is what happens, more or less after disconnection.
This means that something unpleasant has happened to your modem. If this
is immediately after or before disconnection and doesn't last for long,
it is harmless - it just means that the disconnection hadn't yet been
reported
to the driver yet (so it keeps trying to send packets, but these fail
because
the modem is not there anymore): it can take a little while ( 1 second
though)
for the USB core to report disconnections to drivers.
As for why it disconnects in the first place, hard to say. Lots of people
seem to have this problem, and as you noticed it seems to be related to
the
kind of motherboard... Maybe the modem is not getting enough power, or
the
USB cables are too long or passing too close to a source of
electromagnetic
interference? Try plugging the modem into a different usb port (eg: one
on
the back of the computer if you were using one on the front before), and
try to keep cables away from other cables or possible sources of
interference.
Ciao,
Duncan.
