Public bug reported: It works fine in precise and was working up until a recent kernel version. I'll try and pinpoint which one later.
Here is the relevant section from dmesg: [ 3625.798861] usb 5-2: new full-speed USB device number 17 using ohci_hcd [ 3626.225720] input: 2010 REV 1.7 Audioengine D1 as /devices/pci0000:00/0000:00:13.0/usb5/5-2/5-2:1.2/input/input22 [ 3626.225904] hid-generic 0003:1101:0003.000D: input,hidraw0: USB HID v1.00 Device [ 2010 REV 1.7 Audioengine D1 ] on usb-0000:00:13.0-2/input2 [ 3626.233777] hid-generic 0003:1101:0003.000E: hiddev0,hidraw1: USB HID v1.00 Device [ 2010 REV 1.7 Audioengine D1 ] on usb-0000:00:13.0-2/input3 [ 3626.366378] usb 5-3: new low-speed USB device number 18 using ohci_hcd [ 3626.506265] usb 5-3: device descriptor read/64, error -62 [ 3626.750043] usb 5-3: device descriptor read/64, error -62 [ 3626.989835] usb 5-3: new low-speed USB device number 19 using ohci_hcd [ 3627.129729] usb 5-3: device descriptor read/64, error -62 [ 3627.373508] usb 5-3: device descriptor read/64, error -62 [ 3627.613315] usb 5-3: new low-speed USB device number 20 using ohci_hcd [ 3628.021023] usb 5-3: device not accepting address 20, error -62 [ 3628.156903] usb 5-3: new low-speed USB device number 21 using ohci_hcd [ 3628.564501] usb 5-3: device not accepting address 21, error -62 [ 3628.564540] hub 5-0:1.0: unable to enumerate USB device on port 3 ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: linux-generic 3.5.0.3.3 ProcVersionSignature: Ubuntu 3.5.0-3.3-generic 3.5.0-rc5 Uname: Linux 3.5.0-3-generic x86_64 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.25.
