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. HTH, robin [1] it's some cheap mycom thingy which shows up as 16:00.0 USB Controller: NEC Corporation USB (rev 41) 16:00.1 USB Controller: NEC Corporation USB (rev 41) 16:00.2 USB Controller: NEC Corporation USB 2.0 (rev 02) Subsystem: 1033:0035 (ohci_hcd) and Subsystem: 13e6:1201 (ehci_hcd) _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
