I am having a problem with the USB communication dropping out periodically when using the DH67CL motherboard USB ports. If I use a PCI card with USB ports on it the problem goes away.
My application checks the USB connection every 5 seconds or so and reports an error if there is a problem. It reports a problem with the communication about once an hour.
Chipset: Intel 6 series/c200 USB Enhanced Host Controller Driver: v184.108.40.2061
USB Root Hub: v5.1.2600.5512
Windows XP SP3
BIOS Legacy USB: Problem occurs both when legacy support enabled and disabled.
Is this an interruption of the USB communication because the motherboard is busy doing something else? How can I tell?
