USB device not recognized
 
I've been tinkering around following this article and managed to mount USB devices in Slackware 10.0. I followed the instructions in that howto and everything worked fine. I put together a couple of scripts to mount and unmount the device on /dev/sda1 and was happy. :)

This worked for a while. But rather suddenly the system isn't recognising the presence of any USB devices. cat /proc/scsi/scsi shows that no devices are attached. Dmesg also indicates no attached USB device.

I'm stumped. Why would the system suddenly stop recognizing devices after rebooting?

did you do any upgrading lately ?
what's the version of udev that you use ? ( "udev -V " )

No, no upgrading. udev -V gives me no output but this is a fresh install of Slackware 10.0 - I'm not sure if this tells this you or not.

I'm pretty sure I've done nothing that might affect this between it working and it not.

Thanks.

well... did you try different usb devices with different cables in more than one usb port ?
( just to make sure it's not hw . )

and also, did you check the whole dmesg for any errors or warnings ?

Yes, I've tried it with several devices, all not working.

Err... dmesg did give some errors... I gave the command again to see what they were and post them... but... apparently the device is recognised. :rolleyes:

Perhaps it is hardware after all. I'll try some of my flatmates' devices with it.

Thanks.

Not working again. With another device in a different port.

dmesg output:
