Hello,
My usb ports shutdown after going on laptop battery, even though the battery power availability is at 98%. I have set the profile for performance while on battery - no help.
Opensuse 12.1
Any ideas?
Thanks.

you can accidentally pump a lot of amp-hours through a USB port, so
check for power saving settings in the BIOS…
or check the laptop maker’s documentation (maybe there is an Fn switch)

Depending on your notebook scheme, the maximum ampere that are available during mobile usage may not be sufficient to run the same device as when connected to the power grid. This will be particularly true for CD/DVD-reader/burner (external usb) and external HDD, which for this reason frequently ship with two plugs on a Y wire in order to require a divided amount of electrical power on two different usb ports if available.
You will have to read your documentation. Some producers e.g. Samsung provide on their notebook one usb-interface capable of higher power supply while on battery power. But not all models have the feature.
Is the usb port visible (and especially is the device visible) when you go on battery. Post in “code” marks please the output with the device attached, one time with and one time without power grid.
Command is:
lsusb
and it provides you with a list of all available usb devices. Now if this list is different, and you device is one of the aforementioned, then this could be your problem.
Have you tried to google that yet?
Why don’t you share your knowledge? I did google this right now and a part some unspecific issues about HP laptops having heat issues I have found nothing. Did you google it? If so and you did find the solution, why don’t you share? Besides @bhaa02 could you be so kind and specify producer and model of the laptop. Also if this is the 64 bit or the 32 bit version and which desktop environment was choose. Unspecific questions risk to trigger unspecific answers.

LOL, you got me on that DenverD. So welcome first time poster. (What a scratchy character I have 
)
Laptop: Dell Latitude D830. 64 bit. I have tried Gnome and Kde - same issue.
Some additional info: I have used Red Hat 5, 6, and Novel Suse 11.3 with this same laptop and have never had this issue until now. So it seems that something has changed with 12.1 for power management.
Thank you for the assistance…
Yes, there were to all extend changes in the power management, but they “should” not impact the usb function. A thing like that I would have expected to be troublesome with a future Kernel version 3.2.5 onward, as there the ASPM for the PCIe implementations where changed.
Could you post output of the command
lsusb
while on and while off power with the same hardware attached? Thank you.
Bios settings are okay. I will check documentation if there is a FN to turn the ports back on. I never had to do this before with other versions of Linux: Red Hat and Novell Suse. However, it would be nice if my laptop had this functionality… I’ll check.
Thank you.
Here is the output of the lsusb:

Check also if for your laptop there is no update for the BIOS available. Sometimes producer encounter these problems and fix them silently on the download page with a new BIOS, supposing that who has a problem will well go and look.
If they have a new BIOS make sure you follow scrupulously the indications for the procedure, that you are aware of the risks, that your battery is completely charged and do not detach the machine from the grid or switch it off during the update. But you know that I would guess.
If you don’t have a BIOS to charge and if you don’t find a function key and if you experience usb problems the only thing comes to my mind is to look into
/etc/modprobe.conf
/etc/modprobe.d/modprobe.conf
/etc/modprobe.d/options
and to see whether you have a line there that says:
options usbcore autosuspend=1
and set the value to zero:
options usbcore autosuspend=0
Do not make modification without taking written note (on a paper) which file you did edit. This will deactivate the usb autosuspend and therefore heighten you battery consumption and lower your autonomy. But it may solve your issue. If you solve it with this, good. If you do not solve it, in all cases return a switch back the changes you made. Do not abandon non efficient changes.
If you should solve it in this way: this should not be necessary normally so I would file a bug report then telling
- the problem you encountered
- the exact model of the laptop (Dell, modell, if possible also the serial number to identify well the chipset).
- the BIOS version involved
- the work around taken
So by itself all devices seem to be recognized either on sector or on battery. If the problem comes with the logitech nano receiver, this can be the case, as the autousb feature will presume that it is not a keyboard but an other usb device. Since normally only keyboards and input devices are exempted from that function as far as I recall, this may be then the issue. But you should tell us what device exactly does not work.
The Logitech Nano receiver (wireless mouse) stops working. I haven’t tried any another usb devices, which I will; Also, I will try your suggestions in the previous email shortly; I am on a long flight soon, which I will have time to try those and then I’ll get back you. Thanks again!
Have a safe trip. Welcome.

Your direction on the autosuspend led to a solution!
I couldn’t find an options or modprobe.conf file but what I did find was an usb-autosuspend.conf in the following directory:
/etc/laptop-mode/conf.d
In this file the USB autosuspend was set to “auto”; I set this to 0 to turn off this function,- it worked!
Also, in this file you can whitelist devices and set options for on battery and on power - some excellent options here.
12.1 is back on top for me 
Thank you for the support! Have a good day…
First of all, thank you very much for sharing the detailed solution, which is, given you did all the work, your merit and with which you helped others. Thank you for this.
Happy that I was able to be of some help.
Have a good day too.
