|I asked in alsa-users about the state of usb2 audio class compliance some time ago but I never got a definitive answer.. I've done some digging on my own and found someone had a similar issue with the same error about a year ago.
This is what dmesg says when I connect the device in usb2 mode, the last row is the error when I try to use it.
[ 2384.749399] usb 1-2: USB disconnect, device number 2
[ 2390.729825] usb 1-2: new high speed USB device number 3 using ehci_hcd
[ 2390.863654] generic-usb 0003:0926:0202.0003: hiddev0,hidraw0: USB HID v1.01 Device [Sound Devices USBPre2] on usb-0000:00:02.1-2/input3
[ 2418.388135] cannot submit syncpipe for urb 0, error -90: internal error
Here are the lsusb -v as usb1.1 http://pastebin.com/Jj6mXHxJ and here as usb2 http://pastebin.com/8uCBAkNb
I've looked at them and the only thing that differs is the|bInterval, wich is 1 in usb1.1 and 4 in usb2
