Hi Takashi,
I messed up OHCI support; Rui and Matt confirmed that this fixes it.
Do you also need an alsa-driver patch?
kind regards

Subject: Repair snd-usb-usx2y over OHCI
From: Karsten Wiese <fzu@xxxxxxxxxxxxxxxxxxxxx>
The previous patch "Repair snd-usb-usx2y for usb 2.6.18" assumed
urb->start_frame roll over beyond MAX_INT for both UHCI & OHCI.
This isn't true until now (kernel 2.6.20).
Fix this by only looking at the common between OHCI & UHCI Frame number
range.
This is for mainline and stable kernels >= 2.6.18.
