Hi everybody! I'm using Slackware 9.1 with Kernel 2.4.26 patched for low-latency. Everything is ok, only my usb-midi multiport Yamaha UX256 isn't working. I've loaded the usb modules (I use also an usb joypad and a pendrive and they work), I've loaded the usb-midi module and at boot time it recognizes the UX256 and displays the following kernel messages: ---------- May 26 10:48:54 teknobox kernel: hub.c: new USB device 00:1d.1-2, assigned address 2 May 26 10:48:54 teknobox kernel: usb-midi: Found YAMAHA USB-MIDI device on dev 0499:1000, iface 0 May 26 10:48:54 teknobox kernel: usb-midi: Found MIDIStreaming device corresponding to Release 1.00 of spec.

I know it should work beacause I tried with Demudi (www.agnula.org) and it works. I've also recompiled alsa (1.0.4) but nothing to do... Any suggestions? I've tried everything I was able to, i've been Googlin' but no usefull info. If someone has...THANKS! -- =====>?t3<=====
