[Please CC to me any post sent to the linux-usb list in response to this
one.]
Hello all,
on a x86 system, a USB keyboard works as expected and so does a USB
ueagle_atm DSL modem. However, both devices are conflicting when
plugged simultaneously. Only the first plugged device works, while the
second one does not.
(Please see the attachments for further details about the configuration.)
The issue was reproduced on one x86 machine, with a 2.6.33.4-vanilla
kernel and a 2.6.24-vanilla kernel. The aforementioned attachments and
the following debug outputs were obtained with a 2.6.33.4 kernel. The
kernels were compiled with the only features mandatory for booting and
reproducing the issue.
As far as I know, no similar issues have been reported before. The
following patch might be related to this issue:
http://git.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=04ea02f5746a2e01a38edae2de3eafc40eac17aa
The problem can be triggered in two different ways:
Case 1: the USB DSL modem is plugged first; then, the USB keyboard is plugged.
Case 2: the USB keyboard is plugged first; then, the USB DSL modem is plugged.
In both cases, if both devices are unplugged and re-plugged again in
another order, then the issue appears again (the first re-plugged device
works while the second one does not).
* Output common in both cases

Please ask for any other informations I have not provided if you need them
in order to investigate this issue. Although I have no dayly physical
access to the concerned hardware, I will try to do my best to do some
testings.
