usb: testusb: Fix for showing the connection speed

2021-10-09T11:24:30+00:00

[ Upstream commit f81c08f897adafd2ed43f86f00207ff929f0b2eb ]

testusb' application which uses 'usbtest' driver reports 'unknown speed'
from the function 'find_testdev'. The variable 'entry->speed' was not
updated from  the application. The IOCTL mentioned in the FIXME comment can
only report whether the connection is low speed or not. Speed is read using
the IOCTL USBDEVFS_GET_SPEED which reports the proper speed grade.  The
call is implemented in the function 'handle_testdev' where the file
descriptor was availble locally. Sample output is given below where 'high
speed' is printed as the connected speed.

sudo ./testusb -a

tools: usb: testusb: change the default value for length from 512 to 1024

2015-09-27T15:54:31+00:00

For ctrl out test, it needs length > vary, so in order to run it with
default parameters, we do this change.

The 'length' is the transfer length, not the packet size, so
change the help text.

testusb: remove all mentions of 'usbfs'

2013-02-08T20:15:24+00:00

Commit 8a424bf40d772fedacc91862ecc86f10541fabb3 (tools/usb: remove last USBFS
user) removed 'usbfs' files from the source but retained mentions of 'usbfs'
all over the place, most importantly in the misleading error messages printed
in case USB device files are not there.  Remove all the  mentions of 'usbfs'
for good now!

tools/usb: remove unneeded 'continue' and simplify condition

2013-01-12T00:03:37+00:00

Basically remove unneeded code. Since that 'continue' is at the end
of the for() there's no need for it.

tools/usb: remove last USBFS user

2012-09-10T18:10:37+00:00

In commit fb28d58b ("USB: remove CONFIG_USB_DEVICEFS") USBFS got
removed. Since it is gone we can stop using it in testusb and try udev
nodes right away.

testusb: expose looping forever option "l" to user

2012-06-13T23:15:03+00:00

The testusb.c tool has support for looping forever implemented, which
may be useful for stress test, yet it is not exposed to the user, so
even though the code is there, it cannot be used.  This commit adds
"l" to the set of options handled by the application which enables
the feature.

Also, I collate help information for each command line option to make
it easier to use for novice.

As real device-nodes managed by udev whose nodes lived in /dev/bus/usb
are mostly used today, let testusb tool use that directory as one default

USB: testusb: testusb compatibility with FunctionFS gadget

2010-05-20T20:21:43+00:00

The FunctionFS gadget may provide the source/sink interface
not as the first interface (with id == 0) but some different
interface hence a code to find the interface number is
required.

(Note that you will still configure the gadget to report
idProduct == 0xa4a4 (an "echo 0xa4a4
>/sys/module/g_ffs/parameters/usb_product" should suffice) or
configure host to handle 0x0525:0xa4ac devices using the
usbtest driver.)
