PS. Did you
have luck with your UA-25?
Nothing new, I am waiting to get my hands on different hubs to see if
there is any difference.
There is. I just got my hands on both a USB2 hub and a PCMCIA [1] card.
With the USB2 hub I also get
ALSA urb.c:856: cannot submit datapipe for urb 0, error -28: not enough
bandwidth
ALSA midi.c:214: urb status -32
messages and jackd won't start.
but connecting the UA-25 directly to the PCMCIA/USB2 card works if I
also connect some external power supply to the PCMCIA card. Did you try
that?
It also still works with an old USB1.1 hub.
