USB ports not working after resume


The other day I put my Dell Studio 1537 laptop running the latest Mandriva 64 bit Spring edition to sleep, unplugged all my usb devices, and took it to go work somewhere else where I resumed and did my work. When I was done, I suspended again, and returned to my desk. When I plugged all of my USB devices in again (a mouse, my iPod, a flash disk, an external HD, etc) they were not recognized and were not supplied with power. I tried restarting, and they still were not recognized. I switched to my Windows partition, and they were not recognized. I disabled all of my USB ports using Windows, turned off my computer, unplugged the AC and the battery (in an attempt to reset CMOS), plugged everything in again, restarted, enabled all my USB devices, and still nothing. Windows even tells me the USB ports are ready to use. I can't seem to find anything wrong with them in either Mandy or Windows. What can I do? Thanks.

Looks like you've tried what you can, sounds like a hardware failure to me. Try to run Dell's Diagnostics tool by booting off the Drivers CD. I'd suggest calling Dell for a warranty claim & I wouldn't mention Linux if I were you, they often use Linux as an excuse for refusing warranty claim.

I'm inclined to agree with the above poster (hardware problem), but if you're out of ideas, you might want to investigate the BIOS:

1) Toggle the BIOS option called "USB Selective suspend/resume" and see if that does anything (if yours has this option).

2) Update the BIOS if there is a newer version.

Neither of these options may help, but there's not much else on that laptop to be found via Google, about this problem. NOTE: Make sure that if you choose to try updating the BIOS, you do it according to the vendor's or manufacturers instructions on the appropriate website (Dell's website?) so you don't risk voiding the warranty.

As for changing BIOS options, you'll need to enter the BIOS configuration page during very early boot of the machine, and locate whatever option you wish to adjust, and adjust it using something like the UP/DOWN or PAGE-UP/DOWN or SPACE/RETURN keys. After that, you would SAVE the settings (usually the F10 key) and exit the BIOS and reboot.

To enter the BIOS initially, depends on the machine as to what key(s) you press or hold to get into the BIOS. On my desktop, I use the delete key to get into the BIOS; on our laptop, it's the ESC key, followed by the F1 key; on some machines, it's the F8 key. You'll need to check the manual for your machine to see what key you need to use. The manual for the machine should also give a decent over view of the BIOS options available, and what they do and how to adjust them.

As for updating to a newer BIOS (this is called FLASHING the BIOS) you should find instructions both in the manual for the machine, as well as on the vendor or manufacturers website. These days, the website usually offers BIOS updates for download, and instructions on how to flash to a newer version. Also, please read any warning notes on the website where you download the BIOS from; generally there will be a warning telling you that if you flash the BIOS badly, or use the wrong BIOS file, you can make your machine unusable, and it will need to be serviced (a new BIOS installed by a repair shop).
