Hi Greg:
Thanks for your response. Yes, the Keyspan device was plugged in
when I first booted and across subsequent boots, but always with
Linux and some variant of the usb-serial suite. As you suggested,
I powered down, physically removed the device -- so no external USB
devices are connected -- and rebooted. I have usb-serial debugging
enabled in the kernel and usb support compiled as a module (full
listing of my USB kernel options below). After booting I loaded the
modules: usbcore, uhci, usb-serial, then used "logger" to note the
time (16:38:39) in the system log file and then physically connected
the Keyspan PDA. The full syslog is below, including the final Oops.
I also attach "ksymoops" output showing the problem occured due to
a NULL pointer dereference in keyspan_pda_startup(). From the dbg()
messages I added to keyspan_pda_startup() I see that the Oops occured
because serial->port[0].read_urb is NULL at the top of
keyspan_pda_startup().
I should warn you that I've made two changes to the sources while
investigating this (and these are reflected in the logs below):
1. I've added some dbg() calls to help me get oriented in the code.
2. Earlier, when I first realized that the serial->port[0].read_urb
was still NULL at the top of keyspan_pda_startup(), I looked at
the usb_serial_probe() code and noticed that the "read_urb"
element is not set until after returning from the startup routine.
That is, in usb_serial_probe(), the "type->startup (serial)" call
occurs before the loops labeled: "set up the endpoint information".
Thinking that was the problem, I moved the startup code to below the
"set up" loops. (But the problem still persists because "num_bulk_in"
is 0 -- no bulk_in endpoints were found on the Keyspan PDA -- so
the loop that sets up the port->read_urb elements never gets invoked,
even though keyspan_startp_startup() needs a read_urb address to
pass to FILL_INT_URB.)
If you think my change is either wrong or confusing the issue, I'll
reload the vanilla pre4-5 sources and rerun these tests.
Thanks again for your great work on this usb-serial suite and for your
help with my problem.
--Peter
P.S. Appended below are:
1. The USB related entries from my kernel .config file:
2. My system log from restart to Oops.
3. ksymoops output corresponding to the Oops.

Here's the corresponding ksymoops output:
ksymoops 0.7c on i686 2.3.99-pre4. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.3.99-pre4/ (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.
