Command-Line Parameters for the USB Performance Test (Windows Embedded CE 6.0)
1/6/2010
This test measures host-side and device-side performance at the bus level in order to identify general performance issues. The tests include several modes that help you narrow down possible issues. The USB performance test performs transfers at the lowest level of the bus, allowing tracking of performance issues in the bus driver itself.
The following example shows the syntax for the two commands you must run in sequence for the USB Host-Controller Driver test. For information about the Lufldrv command, see Running the USB Host-Controller Driver Test.
Syntax
lufldrv.exe {-1|-2|-3|-f}
tux.exe [tuxparams] -n -d usbperf.dll
