Hi,
I recently got a bug report that included some lsusb -v output
for a Blackberry Pearl that went like this:
UNRECOGNIZED: f0 b3 99 e0 27 eb 69 cc cd 04 33 bb 4f e2 f3

How do I go about debugging this? To my knowledge, the kernel talks
to the device as soon as it is plugged in, and something like usbfs_snoop
won't help me here.
Any tips?
Thanks,
