Notes on USB Speeds:

'Frame size' refers to the data transfer protocol of the TTCUSB to the host which is 64 bits per L1A or short B frame (a long B frame uses 128 bits to transfer to the host).

To find out which speed a device is running, run the program usbtree (get it from here). Make sure the usb filesystem is mounted on /proc/bus/usb . If not, mount it with:

sudo mount -t usbfs none /proc/bus/usb

It's probably easiest to run usbtree twice: one with the device of interest (e.g. the ttcusb) connected and once disconnected and compare the two outputs.
