Hi,
Suppose one TD that has 5 TRBs and each has trb Length of 200 bytes
except last Trb all have chain bit set to 1.
Single TD contains 5 TRBs.

Why doesn't the sysfs function use usb_get_max_power? Am I missing
something?
I have no idea. Updated the function.

changes since v4:
* removed FSF address
* renamed struct usb_8dev
* removed unused variable free_slots
* replaced some _to_cpu functions with pointer equivalent

Hello everyone,
I'm seeing some slightly weird behavior when connecting a Kinect (USB 2
device with internal hub) to my Dell Latitude E6430 (running stock
Ubuntu kernel 3.2.0-34-generic). There are two different cases:

Hello Greg Kroah-Hartman:
in drivers/usb/core/message.c:
at line 943, status is kmalloc ( sizeof u16 )
at line 952, assign the value of status to data
at line 953, free status.
it is better to let "u16 status" instead of "u16 *status = kmalloc...".
thanks.

I'm trying to bring up an OMAP4 system based on Variscite's OM44 module running
Linaro's Ubuntu Precise in a headless configuration. The system contains two
SMSC LAN7500 USB-GigE chips (not dongles), both of which are fully functional.
The GigE chips don't have EEPROMS, so no permanent MAC addr
