You could try updating to the latest 6-stable usb code, which might
possibly help the ohci case. There were a number of quite severe
ohci issues fixed since 6.0-release that might trigger more easily
when using polling. In particular, these revisions may be of interest:

        ohci.c 1.154.2.1
        ohcivar.h 1.40.2.1
        usbdi.c 1.91.2.1
