usb: usbtest: two super speed fixes for usbtest

2012-06-01T07:15:48+00:00

commit 6a23ccd216b6a8ba2c67a9f9d8969b4431ad2920 upstream.

bMaxPacketSize0 field for super speed is a power of 2, not a count.
The size itself is always 512.

Max packet size for a super speed bulk endpoint is 1024, so
allocate the urb size in halt_simple() accordingly.

usb: Provide usb_speed_string() function

2011-09-18T08:29:04+00:00

In a few places in the kernel, the code prints
a human-readable USB device speed (eg. "high speed").
This involves a switch statement sometimes wrapped
around in ({ ... }) block leading to code repetition.

To mitigate this issue, this commit introduces
usb_speed_string() function, which returns
a human-readable name of provided speed.

It also changes a few places switch was used to use
this new function.  This changes a bit the way the
speed is printed in few instances at the same time
standardising it.

USB: use usb_endpoint_maxp() instead of le16_to_cpu()

2011-08-23T16:47:40+00:00

Now ${LINUX}/drivers/usb/* can use usb_endpoint_maxp(desc) to get maximum packet size
instead of le16_to_cpu(desc->wMaxPacketSize).
This patch fix it up

USB: usbtest: use URB_ZERO_PACKET for BULK-OUT transfers

2011-08-23T16:47:39+00:00

Executing
| testusb -a -c 1 -t 3 -v 421 -s 2048

does not complete on the gadget side.
g_zero enqueues a 4096 bytes long buffer. The host sends 2048bytes which
is a multiple of wMaxPacketSize (either 64 or 512 bytes). The host is
done with sending data but the gadget waits for more.
Since the protocol does not include transfer-length-field sending a
terminating zero packet seems the only way out.

usb: fix warning in usbtest module v2

On amd64 unsigned is not as wide as pointer and this causes a compiler
warning. Switching to unsigned long corrects the problem.
