USB Port External Loop Failed

[gregg.s.bergman]

I just bought PC-Doctor Service Center 6 and have ran it on several PC's receiving the following message while running the I/O Port Test; "USB Port External Loop Failed". I'm assuming it is because there is no looping plug on a USB port? There is no looping plug for USB in the kit? How do you perform this test successfully?

Thanks,
Gregg

Gregg,

The PCDR USB loop test in service center 6 will use any USB 2.0 compliant device for this test.  By default all ports are on. By editing the USBTEST.ini file. The file is pretty well commented.

I usually make the following changes;
iPorts=2
I uncomment the above to only test 2 ports (this is done by removing the , this will test ANY 2 ports with proper device plugged in.

iUsingUsbWrap=0
This will set the program to use any standard USB device (thumb drive etc.) for the tests.  This is as opposed to the special Red Parallel / USB wrap cable.

Here is the USBTEST.ini file with the changes made
