Hello, people of the linux-usb list.
I'm having seriouse trouble with the Alcatel Speedtouch ADSL usb modem on my
old
P-60 running Redhat 7.0 with kernel 2.4.2. Some packages (glibc, binutils etc.
are upgraded to Redhat 7.1)
the usb interface card is a cheep noname (chip marked OPTi 7ireLink
(apearently)).
All patching etc is done as explained in the howto, and also the upgrades of
the hotplug package etc.
Recently I also tried to connect my logitech mouse just to see if any usb
devices is working, but with no result. (not the hang explained later on
either). The mouse was not lightened (optical)
What's really bugging me is that I have the _exact_ same setup on my toshiba
(tecra 8100), and here it's all working gracefully. Both tried to copy the
kernel (and modules) directly from the toshiba and recompiled it with the same
configuration on the p60.
modules loaded are speedtch, usbcore and usb-uhci
crash situation:
When i'm connecting the modem, i get two different messages in syslog
(apearently they come "by hazard")
Either the modem is rejecting the id-number it's asigned, or the system
craches with kernel panic: interrupt handler killed. (the pointer changes from
time to time, but in most cases it's null)
I'm including the ksymoops as atachment.

ksymoops 2.3.4 on i586 2.4.2. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.2/ (default)
-m /usr/src/linux/System.map (default)
Warning: You did not tell me where to find symbol information. I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
Warning (compare_maps): mismatch on symbol partition_name , ksyms_base says c01a7f18,
System.map says c014d0d8. Ignoring ksyms_base entry
