I installed hotplug from source. I also tried loading usbstorage manually
and even building it into the kernel. I've tried booting with the device
connected and not connected. I tried plugging in the device after booting
with and without the memory card plugged in initially.
It always hangs in initializing. The kernel both on the Thinkpad and my
generic (white box) tower is 2.4.18. The Thinkpad has the PPDD encrypted
FS and IPSec compiled in but these should not affect anything. I don't
even have sound and suspend enabled (yet).
Could there be something unusual or non-standard about the Thinkpad
w.r.t. USB or is this just some dumb error on my part.
