You say the device works properly under Windows, but you also say that Windows displays a warning message about a problem with the device. These statements can't both be true. Have you tried using the device on a different computer? Does it run okay at high speed on the other machine? Do other high speed devices work okay on your computer? > I run kernel version 2.6.24-rc2. I get the 3strikes error quite number > of times.

It does sound like a hardware malfunction, but from your description there's no way to tell whether the malfunction is in the device or in your computer's EHCI controller. Why do you think the kernel detected a hardware malfunction? The log messages you included don't indicate any such detection. > Please help me fix this bug. Thank you in advance for any help.
