NI USB-9162 not enumerating on USB bus

[FrV]

Hi,

I'm using a NI USB-9162 module on an Intel MB under linux 2.6.26. Sometimes, after a hot reboot, the device does not enumerate anymore on the USB bus.

Cold boot kernel messages for usb 4-4:

I would think this is a bug in the NI USB-9162 module? Anything I can do about it?

Hi FrV,

Which Linux distribution are you using? How often does a warm boot lead to this error: every other reboot/every third reboot/5% of the time? I've been able to reboot 5 times in a row with openSuSE 10.3 without my 9162 showing your problem, which isn't a very thorough test, so I'd like to know how frequently you see it.

Hi Joe,

The kernel is  Linux version 2.6.26-1-686 (Debian 2.6.26-13lenny2) (dannf@debian.org) (gcc version 4.1.3 20080704 (prerelease) (Debian 4.1.2-25)) #1 SMP Fri Mar 13 18:08:45 UTC 2009

I have not counted exactly, but it's probably around 10% of reboots.

In your testing, you were also doings measurements at time of reboot? I think it's the NI USB-9162 being at a specific state at the moment of reboot which causes it to not enumerate on the USB bus anymore.

I'm reluctant to continue testing since you're using a Linux distribution we don't test in our release cycle. If you can recreate the problem in one of DAQmx Base's offical Linux distros [1], then I'll have more confidence looking for problems. Perhaps someone else in the community has also noticed this behavior, but hasn't mentioned it yet.

Why is your USB-9233 taking measurements when you decide to reboot - is there a reason you can't stop and clear the task before rebooting?

Hi Joe,

I will from now on stop the tasks and unload the modules before rebooting and see whether the problem disappears.

I might also run the debian distribution I use now, with a kernel from one of the supported distributions (since the problem is seen at the kernel level).

Thanks for your help,

FrV
