I have a Debian (actually Libranet 2.8.1 originally - but lots of upgrades) desktop. When I plug my USB pen drive in and try to mount it, it says "sda1 not a valid block device" If I run "dmesg" it gives device information, but says this at the end:

However, if I wait for a long time (approximately a few minutes) then "dmesg" says this at the end:

and now the device can be mounted and used as normal. Does anyone know why it is taking so long for the device to become ready? If I use the same drive on other Windows machines or Linux boxes, it is recognized and mounted right away.
I'm using kernel 2.6.7 with hotplug, and I have this fstab entry for the device:
