/F:ON|OFF Turns the “create (test results) files” function on or
off. /F:ON (create
files)
/I:n (n from
3–F) Set PIIX4 interrupt line in USB host controller to
specified IRQ number, unless already set by the BIOS
(see “Setting the PIIX4 Interrupt Line Number”,
above). Use IRQ as set by
BIOS.
/P:X[,Y] Specifies the (one or two) USB ports to be tested. If a
single port is specified, it should be connected to the
“CH 1” connector on the HPT box. /P:1,2 (test ports 1
and 2)
/S:ON|OFF Turns the “end of test” indicator sound on or off. /S:ON (sound on)
/V:VENDOR Specifies (in HEX) a vendor ID for the host controller.
Note: In this case, the HPT software will not do
automatic search; this option should be used in
conjunction with option /D.

Examples:
1. USB_HPT /s:off /p:2 Test host USB port number 2 without activating the
indicator sound.
2. USB_HPT /a /c > test.res Terminate automatically one second after the test, and send
the output to a file named “test.res”.
3. USB_HPT /v:1042 /d:c068 Test a host controller with the specified vendor and device
IDs.
5. HPT SOFTWARE FUNCTIONALITY
The DOS-based HPT software runs on the USB host unit under test; it communicates with the HPT
box via the USB host controller on the motherboard. For each USB port, the software program
checks for proper operation in both full- and low-speed modes. When all tests are successful, the
software declares the USB host to be functional; any failures are reported on the computer
display screen, and saved on the hard disk as a text file.
Initially, the test program attempts to determine (using the PCI protocol) whether or not the system
under test is equipped with a USB Host Controller; if such a controller is not found, the program
aborts with an explanatory error message.
5.1 Host Test Initialization
Once a USB host controller is identified, the HPT application proceeds to:
1. send a command to reset the USB Host Controller;
2. find the HPT test device connected to the USB port(s) under test (If not found, the
program alerts the user—there may be a setup problem—and fails the test.);
