Hi all:
I'm new to USB and to this list. Thanks to all of you for your splendid
work on this stuff! I've reviewed the mailing list archives but I still
have a question.
I'm trying to get a Keyspan USB PDA adapter working with my system (Intel
box running 2.3.99pre4-5 and Greg Kroah-Hartman's usbserial patches from
this weekend), but the usb-serial module Oops'es in keyspan_pda_startup().
I did some investigation and see that the Oops stems from the fact that
serial->port[0].read_urb is NULL when we call keyspan_pda_startup(),
so the FILL_INT_URB trying to setup the receive interrupt urb fails.
Looking back at the system messages file, I see that the USB subsystem
finds only two endpoints on the Keyspan device: an "Interrupt in" and a
"Bulk out". Shouldn't there also be a "Bulk in"? It looks like the
code in "usb_serial_probe" depends on finding a "Bulk in" endpoint for
setting up the serial structure that it passes to keyspan_pda_startup().
Does it look like I have faulty hardware or do I need to do some more
digging in the code to track down my problem? Thanks for any suggestions.

P.S. Here's an extract from the system log showing the two recognized
endpoints:
