my tascam us800 works great in 3.8.0-21 except for one issue... no usb-mixer

here is output of lsusb -v http://studio213.us/usbif.txt

here is output of alsa-info.sh http://www.alsa-project.org/db/?f=336a5faa6233bc80a856089e657d80da1d32e081

alsamixer -c 1 shows amixer: Mixer hw:1 load error: Connection timed out

dmesg when I do that shows

[115350.348159] cannot get ctl value: req = 0x83, wValue = 0x101, wIndex = 0x1f00, type = 4 [115351.348158] cannot get ctl value: req = 0x81, wValue = 0x101, wIndex = 0x1f00, type = 4 [115732.480250] cannot get ctl value: req = 0x83, wValue = 0x101, wIndex = 0x1f00, type = 4 [115733.480241] cannot get ctl value: req = 0x81, wValue = 0x101, wIndex = 0x1f00, type = 4

plugging in the card shows [ 45.550396] usbcore: registered new interface driver snd-usb-audio

in dmesg

any info on how I might access this usb-mixer built into this card?
