[LAU] Roland A500S: snd-usb-audio error -5

[Francesco Ariis]

Hello linux-audio users,

    I recently acquired a roland a-500s midi keyboard and I have problems
using it under linux. When I connect the device via usb, dmesg tells me
this:

[   68.100184] usb 3-1: USB disconnect, device number 2
[   73.700119] usb 3-1: new full-speed USB device number 3 using uhci_hcd
[   73.860157] usb 3-1: New USB device found, idVendor=0582, idProduct=010d
[   73.860162] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[   73.860165] usb 3-1: Product: A-500S
[   73.860169] usb 3-1: Manufacturer: ROLAND
[   73.867172] snd-usb-audio: probe of 3-1:1.0 failed with error -5

And this is the relevant portion of lsusb -v:
