I get an almost identical output from lsusb as Roy - even
to a cordless laser.
Does the "1.1" in the last line (Bus 2) and the 2.0 on the first
line (Bus 1) refer to the usb version and thus the speed of the
hub? And if so, does that mean that all devices on that bus
run at the same speed?
I ask because the primary difference between Roy's output and
mine is the presence of a "8 in 1" media card reader as
device 2 on bus 2, the slower bus.
