This patch was already sent on 2009/07/08, but the problem is still present in trunk. It has already been applied long time ago: commit 1fa63e43e64596455938e09d3e6ec89eb0c4bbc8 Author: Michael Buesch <mb@bu3sch.de> Date: Wed Jul 8 21:54:28 2009 +0200 usb-ohci: Fix endianness issue This fixes a possible endianness issue in the usb-ohci hw module. hcca.frame and ohci->frame_number are 16bit, so use cpu_to_le16().

This fixes a possible endianness issue in the usb-ohci hw module. hcca.frame and ohci->frame_number are 16bit, so use cpu_to_le16(). Signed-off-by: Michael Buesch <mb@bu3sch.de> --- Resend.
