I'm having a problem with Pendrives in general. My "manufactured for
Memorex by Trek" 256M Drive came up in 10 seconds on FreeBSD 4.8. In
4.9 since the MFC it takes two minutes and ten seconds. I suspect that
some quirk got turned off and that the machine it timeing out some
SCSI commands at startup. I would love to get the old behaviour
back. I've built a debugging kernel with CAMDEBUG turned on. Here's
what happens:

It looks like the first inquiry command is timing out and then the
code changes the CDB from "12 0 0 0 24 0" to "12 1 80 0 ff 0" which
succeeds. This may just be a matter of needing some more time for the
device to settle before it's probed. I say that because the device
comes right up when the kernel is booted.
I can send you more detailed information if you would like. The usb
device id is Vendor: 0x0a16 Product 0x9780. It's a Trek 256Mb
Thumbdrive manufactured for Memorex.
Thanks for any help you can provide. (I can look into this more deeply
on my own if you can give me some pointers)
