Fascinating thread particularly as we may have to abandon our 2018 MBP for recording purposes.
How are you measuring these errors and glitches? I haven't seen the same dialogue on OSX and iOS...

Sounds like he is using the built-in error detection of Samplitude.
The task manager doesn't really tell about such issues.

Interesting indeed.
+1 for a "Gelpad" based solution for mouse pad :-)

this would be my dream setup! start record in digicheck, put it in the Rack and control the in ear mixes with an iPad.
no expensive Laptop on Stage and a "wlan adapter" for the UFX.

Amazing... two independent USB 2.0 ports is great for such a cheap tablet, as far as I can see. Surface 3 has only one USB3 (extendable via docking station).

Any new insights on the Madiface XT not collaborating properly here?

One more... The USB OTG cable works much better than the mini-hub, and turns the Micro-USB port into a full-fledged USB 2 connection, even with an additional external hub. The SSD will do transfer rates of well over 30 MB/s here. With the hub, I can connect the mouse, the SSD, and the card reader. The connection could probably host an audio interface as well. So now it is possible to separate the disk drive and the audio interface, no hub required to connect both to - even though that is not a problem in terms of bandwidth.

Recording with the card reader works fine at lower channel counts, and Samplitude shows sensible disk load values. The little hub here works fine as well, even without external power, running a Madiface USB or Babyface and the card reader or the SSD. With the Babyface instead of the Madiface, I can also connect a mouse, no issues with USB resources.

Yes and no... There are so-called USB On The Go cables and hubs to connect external gear to these Micro USB ports. I ordered a hub, a cable is on the way.

No use trying to connect a drive or audio device to this little hub, though, transfer rates are dismal, well below 1MB/s. I'm not sure whether that is because of the hub or the port, will try the cable when it arrives. It does, however, let me connect a mouse, which did not work on the other hub.

Quite apparently, there is no bandwidth issue with the USB 2 hub, using Madiface USB and diisk drive together works well. What amazes me most is the stability of this system. I am currently recording 64 channels to the SSD, while streaming HD Youtube video across Wifi - and transferring the desktop including audio (without interruptions) to another PC on the LAN with Teamviewer... Also tried a USB 3 card reader with an Micro SDXC card, but was getting disk overload after some time, strange... Will test this further later, and also try the device with the UFX. [EDIT] Sseems connecting a card reader to a hub may not work too well. The one that works with my UFX also fails, and does not seem to report back correct disk usage rates... Will try a pen drive next. :-)

I read that there is not only a common USB 2.0 port but also a micro usb (2.0?) on the Trekstor tablet. Is it possible to use the micro usb like a standard USB 2.0 port, this way avoiding a hub when connecting audio interface and storage device?

Yes, the Surface is quite tempting... I wouldn't really speak of "limited" performance, though, 64 channels is quite something for such a device, is it not? It's the internal SD card reader that is a bit slow. But for smaller recording sesionss of 8 tracks or so, it'll do. Or you could use the internal drive. Will also test an external SD card reader, like the cheap lil' thing I successfully use with the UFX.

Really interesting, thanks for investigating!

So I understand with this hardware it is important to use external drive (SSD), and USB 2.0 limits overall performance somehow, more than the rest of the hardware does.

Microsoft Surface 3 has USB 3, however it's 600 EUR...

And finally, in a somewhat more realistic setup, UFX and a Micstasy recording 20 channels to the SSD. Will leave this running for a few hours. The internal SD card reader again disappoints somewhat, and needs very high buffer settings for reliable recording.
