In my daily logwatch E-Mail I have just noticed the following:-
WARNING: Kernel Errors Present EXT2-fs (sdd): error: can't find an e ...: 1 Time(s) EXT3-fs (sdd): error: can't find ext3 ...: 1 Time(s) ... ... ... usb 2-1.1: device descriptor read/64, error -32 ...: 4 Time(s)
This possibly explains why the USB flash drive that was /dev/sdd failed to automount. It can be mounted without problems manually using a straightforward mount command.
Can anyone explain what I need to do to fix it? The flash drive has a FAT16 file system on it as is normal I think.

To add a little more information here is the sequence in syslog at the end of the sequence when the USB drive is plugged in:-

... and that's it, nothing more happens and the drive doesn't get automounted.
I guess the "Kernel Errors" message from logwatch is just telling me that it looked for EXT3, then EXT2 and didn't find them. It does the same for EXT4 but since the word 'error' isn't in syslog then logwatch doesn't report it.
Looking further I realise too that the 'errors' only happen if/when the USB drive is plugged in at system boot time.
So, they're not really errors and probably not related to my "why don't USB drives automount" problem.
The same USB drive works perfectly (i.e. automounts) in another xubuntu 11.10 system.

What log entries do you get on the working system?

Exactly the same up as far as the error messages, then no errors but the USB stick automounts:-

Just out of interest are the system id partition flags set correctly ? Doesn't explain why you don't get the problem elsewhere but it can cause problems with automount.
Does this happen with "any" USB stick or usb removable media (card readers/USB drives etc)

What do you mean by "system id partition flags"? If you mean the partition ID values shown by (for example) fdisk then they look fairly OK to me:-

Yes, or at least I haven't found anything that automounts since the problem showed itself.
CDs/DVDs don't automount either, the drive spins up and does all the usual actions but nothing appears anywhere.
