Hello all,
Aurélien
The M-Audio Fast-Track Ultra (USB 2) is not recognized by ALSA when plugged on a USB 3 (XHCI) port on the kernel 3.9 9
I'm trying to figure out where the problem lies to report the issue to the proper team: is it with XHCI or with ALSA?
In dmesg, this is what happens with the FTU is plugged:
[ 107.461175] usb 3-1: new high-speed USB device number 3 using xhci_hcd
[ 107.481695] usb 3-1: config 1 interface 3 altsetting 0 bulk endpoint 0x7 has invalid maxpacket 8

[ 107.483899] usb 3-1: can't set config #1, error -22
The device is seen by lsusb, but I don't think it really means much:
Bus 003 Device 004: ID 0763:2080 Midiman M-Audio RunTime DFU
aplay -l only doesn't show the sound card, even if I try to modprobe snd-usb-audio manually:
**** List of PLAYBACK Hardware Devices ****
card 0: MID [HDA Intel MID], device 0: 92HD81B1X5 Analog [92HD81B1X5 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
The same FTU soundcard works on the same machine when plugged on a USB2 port (EHCI).
The Edirol UA-25Ex works on this USB3 port.
What do you guys think?
Is the issue with XHCI or ALSA?
Thanks in advance for the help!
