• LVDS chip on USB base card: FIN1047 driver
  • LVDS chip on TTCrx mezzanine card: FIN1048 receiver (note that the schematics above has a 1047 so does not correspond to the hardware I have in my hands)

Notes on USB Speeds:

Standard Speed Speed divided by 8 bits Speed divided by frame size of 64 bits
High Speed 480Mbits/s 60 MBytes/s 7.5 MFrames/s
Full Speed 12Mbits/s 1.5 MByte/s 0.1875 MFrames/s
Low Speed 1.5Mbits/s 0.1875 MByte/s 0.023 MFrames/s

'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.
