USB devices randomly disconnect

ljones0 · 02-23-2012, 06:36 PM

Hello all, I'm having a severe problem with slackware current (and also 13.37, I've tried using both) with USB devices disconnecting randomly - namely USB memory sticks.

The motherboard is a Asus M5A88V EVO motherboard (64 bit), 16 GB Ram, PCIE video card (ATI Radeon HD 4850).

I've also tried compiling and installing a new kernel with the instructions here - http://standardcode.eu/blog/linux/co...slackware.html . I've tried compiling and installing kernel 3.1 and kernel 3.3 rc4, and I get exactly the same random USB disconnect problems.

Here's an example of what I get in dmesg;

Code:

I thought that there was a possibility that this might be being causes by USB 3 problems, however disabling the USB 3 (this motherboard has USB 3 on board) made no difference.

Is this some sort of hardware failure, bad or broken driver? Older systems with linux installed don't seem to have this problem at all.

Hi ljones,

Maybe I can ask a few questions that come to mind that may help others find you some answers.

1. Is this more than one USB device/disk, or the same one each time?
2. I'm going to assume you've tried different USB ports? Front and back ports (if applicable)?
3. Have you checked the bios for any USB power save options that may, or may not cause disconnections?
4. When you plug in the device(s), are you able to access them at all before they disconnect? If so, how long typically?
5. Are these devices powered (meaning do they have their own power cable), or are they getting power from the USB port? If they are getting power from the usb port, what type of devices are they, and what wattage of power supply do you have? Could it be that you're running out of power, and the USB is essentially turning itself off? (this was a personal issue of mind a while ago).

Ok, lets start there and see where that takes us

There is more than one USB device plugged in, a USB wifi RTL8187 device and a usb mouse. Those are the only things though.

2. I'm going to assume you've tried different USB ports? Front and back ports (if applicable)

I've tried the two front ports (connected through a device called a Pluscom 5.25 Media dashboard, basically it has holes for usb, sata, sd, etc), just a front port adapter. Not tried the back ones though.

**EDIT** I have now tried the rear USB ports and these worked better than the front ports (through the pluscom device).

3. Have you checked the bios for any USB power save options that may, or may not cause disconnections?

I've tried disabling all power management (most noticably ACPI) but it seemed to make no difference.

4. When you plug in the device(s), are you able to access them at all before they disconnect? If so, how long typically?

It almost feels random. Sometimes I can use it for a while maybe (at a rough guess, as I didn't time it exactly) maybe 10 or 20 mins within qemu. At other times it can be mere seconds, just enough time for KDE to load up icons.

5. Are these devices powered (meaning do they have their own power cable), or are they getting power from the USB port? If they are getting power from the usb port, what type of devices are they, and what wattage of power supply do you have? Could it be that you're running out of power, and the USB is essentially turning itself off? (this was a personal issue of mind a while ago).

Nope, all the devices I'm using are powered right off the USB ports.

Ok, lets start there and see where that takes us

Thanks for that

Some more information --

I've now bought a new power supply -- the old power supply is a "noname" brand but is rated at 800W. The power supply I bought this time is a little smaller (750W) but is branded as an OCZ Technlogies ZT series power supply.

After plugging in the new power supply it appears to be at first doing the same as the old one - random USB disconnects.

btw, this is the device (the pluscom media dashboard or as close as I can get to a picture of it) - http://www.ebay.co.uk/itm/3-5-25-USB...item35b1ad5dc9

Prehaps I'm looking at a duff pluscom media dashboard or (worse) faulty USB headers on the motherboard? I'm not sure why the pluscom device and the motherboard would be incompatible.
