On Debian (and Ubuntu) I've always gotten errors with descriptor
fetching if I try to run lsusb as a non-root user. For example:
sarah@xanatos:~$ lsusb -v -d 1d6b:0001

can't get hub descriptor: Operation not permitted
cannot read device status, Operation not permitted (1)
The descriptors are fetched fine when I run lsusb as root. This is probably
due to file permissions, but do you really want to move lsusb out of sbin?
