Hi, folks.

The bcdUSB field reports the highest version of USB the device
supports. The value is in binary coded decimal with a format of 0xJJMN
where JJ is the major version number, M is the minor version number
and N is the sub minor version number. e.g. USB 2.0 is reported as
0x0200, USB 1.1 as 0x0110 and USB 1.0 as 0x0100.

As suggested:

# lsusb -s0 -v

Bus /dev/usb Device /dev/ugen0.2: ID 0763:2012 Midiman
Device Descriptor:
  bLength                18
  bDescriptorType         1
  bcdUSB               1.10
  bDeviceClass            0 (Defined at Interface level)
  bDeviceSubClass         0
  bDeviceProtocol         0
  bMaxPacketSize0         8
  idVendor           0x0763 Midiman
  idProduct          0x2012
  bcdDevice            1.00
  iManufacturer           1 M-Audio
  iProduct                2 FastTrack Pro
  (...)

So, Hans, I think my interface is not eligible for the USB2.0 test you
need, right?
