odd usbdevs output

Hi all,

I recently acquired a USB stick which seems to work with umass but shows
odd output in "usbdevs":

% keramida_at_kobe:/home/keramida$ sudo usbdevs -dv
% Password:
% [...]
% Controller /dev/usb4:
% addr 1: high speed, self powered, config 1, EHCI root hub(0x0000), Intel(0x0000), rev 1.00
%   uhub4
%  port 1 addr 2: high speed, power 80 mA, config 1, USB Mass Storage Device(0x0163), ????????y(0x1307), rev 1.00
%    umass0
% [...]

Does the odd `????????y' vendor name mean that the kernel prints random
`garbage' here?  If that is so, how can I use kdb and watch this while
it happens?
