commit 95ed56939eb2eaa4e2f349fe6dcd13ca4edfd8fb
usb: ohci: limit the number of link eds
This patch causes Mac OS X to continuously print this message:
USBF: 35.508 AppleUSBOHCI[0x1187000] Watchdog detected dead controller (hcca #: 0, hc#: 863)
I used git bisect to find this patch. None of the USB devices work when connected to the OHCI USB controller.

Hmm, ok, appearently the limit is too strict for macos. Can you try to
increase ED_LINK_LIMIT ?

I used the value of 20 and it worked.
