Hi,
I'm sorry to be late for reply but I have a short vacation in this week.
Same here, I was in vacation in Asia until late last week!

Before vacation I made arrangement to buy Focusrite Saffire LE in used market and today it arrived. As long as I can see, the unit uses the same firmware which your unit uses.
Great, thanks for that...
At startup it lights green ok, but no sound is playable, then the lights turn orange (like it is when it's not working), I hear a "relay sound" (a electric clic of a relay), then, the Saffire LE disapears from the sound menu in Ubuntu sound menu.
I can regenerate this phenomena.
Uff! :)
I can see this in dmesg:
[ 19.083583] snd-bebob fw1.0: Detect discontinuity of CIP: 10 50 [ 19.746665] snd-bebob fw1.0: Detect discontinuity of CIP: A0 A8 ...

I can see as well.
Then, I realized that these discontinuity occurs in packet streaming of 'second or later'. In short, once disconnection of packet streaming, the unit transfers packets with discontinuity in packet streaming of reconnection. Furthermore, the discontinuity is in the early isoc cycles of packet streaming.
I've already commit to avoid the detection of discontinuity in recent commit for v5.5 kernel (under development): https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git/commit/sound...
Thanks for the patch, unfortunately I don't have time until this week- end to test the linux kernel version of the patch..
BUT:
In this patch, isoc packets from the device are captured enough after connection to skip early cycles of packet streaming, thus the discontinuity is not detected.
As long as I tested, this version of ALSA BeBoB driver works well with the device. I'd like you to test with backport drivers as well: https://github.com/takaswie/snd-firewire-improve
I tested this DKMS version, it's easier for me and with less impacts.
What I can say is that my unit is running now normaly on my computer, with
$ uname -a Linux deiphobe 5.3.0-20-lowlatency #21-Ubuntu SMP PREEMPT Wed Oct 23 17:03:51 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
kernel, on Ubuntu 19.10
Running the simple DKMS install version on the README of the snd- firewire-improve, with a recent git clone
Tell me if you need more information so far.
I continue on testing things, but for the moment, 0 problems (I also have a audio unit on USB (GTX headset on USB) for audioconferencing stuff (Zoom) and so far, no problem at all, I can use both.
Same with the NVDIA output over HDMI, on my screen (with a crappy small stereo inside the screen).
Very cool to have the ADAM F7 monitors sound back!!!!!!
**thanks**** !!
