USAGE: benchmark [list]
|
|
[pid=] [vid=] [ep=] [intf=] [altf=]
|
|
[read|write|loop] [notestselect]
|
|
[verify|verifydetail]
|
|
[retry=] [timeout=] [refresh=] [priority=]
|
|
[mode=] [buffersize=] [buffercount=] [packetsize=]
|
|
|
|
Commands:
|
|
list : Display a list of connected devices before starting.
|
|
Select the device to use for the test from the list.
|
|
read : Read from the device.
|
|
write : Write to the device.
|
|
loop : [Default] Read and write to the device at the same time.
|
|
|
|
notestselect : Skips submitting the control transfers to get/set the
|
|
test type. This makes the application compatible
|
|
with non-benchmark firmwared. Use at your own risk!
|
|
|
|
verify : Verify received data for loop and read tests. Report
|
|
basic information on data validation errors.
|
|
verifydetail : Same as verify except reports detail information for
|
|
each byte that fails validation.
|
|
|
|
Switches:
|
|
vid : Vendor id of device. (hex) (Default=0x0666)
|
|
pid : Product id of device. (hex) (Default=0x0001)
|
|
retry : Number of times to retry a transfer that timeout.
|
|
(Default = 0)
|
|
timeout : Transfer timeout value. (milliseconds) (Default=5000)
|
|
The timeout value used for read/write operations. If a
|
|
transfer times out more than {retry} times, the test
|
|
fails and the operation is aborted.
|
|
mode : Sync|Async (Default=Sync)
|
|
Sync uses the libusb-win32 sync transfer functions.
|
|
Async uses the libusb-win32 asynchronous api.
|
|
buffersize : Transfer test size in bytes. (Default=4096)
|
|
Increasing this value will generally yield higher
|
|
transfer rates.
|
|
buffercount: (Async mode only) Number of outstanding transfers on
|
|
an endpoint (Default=1, Max=10). Increasing this value
|
|
will generally yield higher transfer rates.
|
|
refresh : The display refresh interval. (in milliseconds)
|
|
(Default=1000) This also effect the running status.
|
|
priority : AboveNormal|BelowNormal|Highest|Lowest|Normal
|
|
(Default=Normal) The thread priority level to use
|
|
for the test.
|
|
ep : The loopback endpoint to use. For example ep=0x01, would
|
|
read from 0x81 and write to 0x01. (default is to use the
|
|
(first read/write endpoint(s) in the interface)
|
|
intf : The interface id the read/write endpoints reside in.
|
|
intf : The alt interface id the read/write endpoints reside in.
|
|
packetsize : For isochronous use only. Sets the iso packet size.
|
|
If not specified, the endpoints maximum packet size
|
|
is used.
|
|
WARNING:
|
|
This program should only be used with USB devices which implement
|
|
one more more "Benchmark" interface(s). Using this application
|
|
with a USB device it was not designed for can result in permanent
|
|
damage to the device.
