This patch fixes validation of maxpacket value given in endpoint descriptor.
Added check of maxpacket for bulk endpoints.
Correct maxpacket value is:

ISOCHRONOUS 10231024

This patch changes ep maxpacket value from 512 to 1024, becouse it's needed
to handle interupt and isochronous endpoints in high-speed mode. This change
doesn't affect on driver functioning, becouse fifo size (3072) is still enough

Perhaps it's worth expanding "hs" to "high speed" for clarity?

You might want to move usb_get_hub_port_connect_type() to
include/linux/usb.h instead of doing this. Also, I think you need to
mark it EXPORT_SYMBOL_GPL in core/hub.c or you could run into trouble
when both xhci-hcd and usbcore are compiled as modules.

Hi,
This set of patches fixes a few places where the endiannes was not
being converted for the dwTransferID field of transfer requests and
transfer results. It also adds the xfer ID to some debug prints to aid
in bus log analysis.
Thomas Pugliese (2):
fix endianess issues when using dwTransf
Include the xfer_id in debug prints for transfers and transfer segments.
This makes it much easier to correlate debug logs to USB analyzer logs.
