There may be two unrelated things going on. You could try addressing this
first
just to see if it gets rid of some error messages:

I think that may be indicating that the interface will only run at 48k, but
your software is currently attempting to open the interface with a 44.1k
setting.  Or possibly the reverse, but I think indicating the device runs
at 48k.

I found the errno program to convert the error number to descriptions:
~]$ errno 71
EPROTO 71 Protocol error

That seems like the USB stack complaining that device does not implement
 USB protocol correctly, or possibly is not responding correctly for a USB
HID type device.

The newer laptop does not get the same error (the complaint about sample
rate is still present).

I do not understand the error 32 generation:
$ errno 32
EPIPE 32 Broken pipe
