USB sticks, occasionally not detected, occasionally detected.

djolk · 2011-06-14 23:45:56

I have this thing where sometimes USB sticks, SD cards etc are detected and mounted properly, and sometimes not at all. Seemingly after boot things work, and then stop once the computer has sat around for a bit. Its a laptop so its suspended and resumed a fair amount. Though there is no pattern I can discern to this, cold bootings, power cord, anything like that doesn't seem to regularly restore the functioning of USB devices. When not working nothing shows up in dmesg, and the lights on the USB key don't come on.

Interesting, and possibly related or not, when I was looking in log files to see if anything was logged, most of them are blank.

USB modules are loaded and not complaining.

When things are working, everything works fine...

And when it works, dmesg has meaningful messages describing the goodness?
I assume lsusb is silent as to the new device when it fails ?
Can you post the output of lspci when things are working?
Is the lspci output the same when it is in the failed state?
Is your SD card being read through the USB system, or is it a separate PCI device?

So this is when things work. I will have to post later when things stop working.

It calls it a cdrom - but it seems to work.

Okay, dmesg works as expected when things are working -- Good. Unfortunately, I need a few more lines to determine which USB bus it is on; but it is not a big deal. I can see it is on the USB 2.0 bus as opposed to a USB 1.1 bus.

It is normal for Sandisk devices to mount as a CDROM. They usually report and mount as multiple drives, A CD ROM with Window Drivers and Software that circumvent the no USB autorun on Windows, and also a USB disk drive.

I don't see any built in way to read a SD. Do you use an adapter?

Really? I haven't seen this. I have a sandisk 8gb micro cruzer and it mounts as a usb drive.

Is yours a U3 device ?

There is a built in SD card reader. Here is what dmesg says when I insert one:

A new line appears with lsusb!

ewaller · 2011-06-15 17:18:48

Okay, that makes sense. I was trying to establish whether the SD card reader is a USB device (which it is, but it appears to stay quiescent until a SD is inserted) or whether the SD card reader is a separate PCI device, is at is on my machine. It changes the fish-bone diagram a bit.

zenlord · 2011-06-16 11:04:33

I dont know if it is related, but one time after HAL was removed from my archlinux-box, I had resorted to using udev-rules. Now with udev and udisks being a perfect replacement for HAL (at least on my machine), those udev-rules were causing problems, f.e. sometimes having to insert, remove and re-insert the USB-device before it was mounted etc.

Now I don't have anything related to USB or CD-rom in my /etc/fstab, I don't use HAL or udev-rules to automount and rely solely on udisks.

Worth a look?

djolk · 2011-06-17 01:36:19

I'm assuming you created these udev-rules?

I'll look into it but this system is pretty bare as for as config files go.

ewaller · 2011-06-17 02:07:46

Zenlord,
But I would expect dmesg entries when the unit is attached, regardless of udev; In fact, i'd expect to see more messages.

djolk · 2011-06-17 02:36:58

I agree - it almost seems to be like the usb system is sleeping.

djolk · 2011-08-23 20:53:57

So, I think that this might be something to do with laptop mode tools auto-suspending the USB system. I've disabled it for now and everything is detected immediately and works. But, it seems, to my mind, that there should a way to wake the USB system up when I plug a usb device in.
