Thanks for the debugging output. From what I can tell from the HAL log, hal
immediately saw the USB device itself (the USB driver and the storage device),
but never saw the actual mountable volume (which appears three minutes later).
Can you manually mount the stick after these three minutes with

 pmount /dev/sda1

? Check if /media/sda1 contains your USB stick data afterwards.

I also evaluated your kernel log:

[4294798.315000] usb 5-6: new high speed USB device using ehci_hcd and address 2

that's the time when you inserted the stick, I assume.

[4294803.890000] SCSI device sda: 512000 512-byte hdwr sectors (262 MB)

(5 seconds later) the kernel saw the raw storage device (hal sees it at that time)

[4294889.962000] usb 5-6: reset high speed USB device using ehci_hcd and address 2

This operation takes 1 minute and 26 seconds.

[4294977.257000] sda: assuming drive cache: write through
[4294977.257000]  /dev/scsi/host2/bus0/target0/lun0: p1

another minute and 26 seconds later the kernel finally recognizes the partitions.

These delays seem to match the three minutes you described.

One question: are you sure that you rebooted? An uptime of 4294977 seconds means
49.7 days! Maybe there is another bug in here?

Can you please also try another thing? Remove the stick, do

  sudo rmmod ehci-hcd

and try again. This will remove the USB 2.0 kernel driver and use the slower,
but maybe more robust 1.1 driver.
