[Voyage-linux] USB DAC problems with Voyage 0.8 and new Voyage 0.8.5

[Kim-man 'Punky' TSE]

Hi Bruno,

I used XMOS USB 2.0 development board and also got the same "cannot get ctl value" warning like below:

root at voyage:~# dmesg|grep can
[    7.972152] cannot get ctl value: req = 0x83, wValue = 0x201, wIndex = 0xa004
[    7.973150] cannot get ctl value: req = 0x83, wValue = 0x200, wIndex = 0xa004
[    7.974282] cannot get ctl value: req = 0x83, wValue = 0x201, wIndex = 0xb004
[    7.977419] cannot get ctl value: req = 0x83, wValue = 0x200, wIndex = 0xb004

But my 0.8.5 MPD test bed works very well, see my "lsusb" and "cat /proc/asound/cards" below:

Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID 20b1:0002 XMOS Ltd
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

  0 [X20            ]: USB-Audio - XMOS USB Audio 2.0
                       XMOS XMOS USB Audio 2.0 at usb-0000:00:0f.5-1, high speed

Show me the output of "mpc play" then.

Regards,
Punky
