That is surprising, to say the least: it kills the USB2.0 driver in

and am recording with high sample and bit rates not likely to work with
USB1.1 speeds.
So if that's correct, the US-144MKII probably switches into some mode
unknown to ALSA in USB2.0 while the US-122L stays workable.

Can report the same for a Tascam-122L though this
uses a special
"usbstream" method that is so obscure that you cannot find any
documentation for it and need to spell it out in your asoundrc file.
Some documentation about the usbstream method here:
