identifying device associated with USB device?

[spiderpig]

I'm writing a shell script which will copy files over to a USB flash drive. Other than grep the output of dmesg, is there any other way to determine what device node is attached to a USB device? It appears that usbdevs doesn't help either.

Any insight would be appreciated. Thanks.

Before I plug in my USB external disk

$ sysctl hw.disknames
hw.disknames=wd0,wd1,cd0,fd0

After plugging in

]sysctl hw.disknames
hw.disknames=wd0,wd1,cd0,fd0,sd0

This is what dmesg reports

umass0 at uhub0 port 4 configuration 1 interface 0
umass0: Prolific Technology Inc. Mass Storage Device, rev 2.00/1.00, addr 2
umass0: using SCSI over Bulk-Only
scsibus1 at umass0: 2 targets
sd0 at scsibus1 targ 1 lun 0: <HTS42404, 0M9AT00, MA2O> SCSI0 0/direct fixed
sd0: 38154MB, 4864 cyl, 255 head, 63 sec, 512 bytes/sec, 78140160 sec total

Don't know what is easier to parse

Thanks, J65nko! I ended up going a different route, but I had forgotten about poking about the sysctl variables. I won't be likely to forget next time.
