Driver anchors the tx urbs and defers the urb submission if
a transmit request comes when the interface is suspended.
Anchoring urb increments the urb reference count. These
deferred urbs are later accessed by calling usb_get_from_anchor()
for submission during interface resume. usb_get_from_anchor

it seems that data are interpreted differently. While the host is
getting tons of -71 errors, data is passed to vmware correctly.
I've attached two traces that I ran simultaneously on the host and the
guest. One thing that I noticed is that the same camera is setting
different video standards

Sarah,
We've found the TD_size issue when developing a new XHCI host controller also:
1. need fix xhci_td_remainder() and xhci_v1_0_td_remainder()
2. we need to use DIV_ROUND_UP() instead of roundup() when we
calculating total_packet_count .
As in recent kernel versions, roundup() is defined as f
