I read the post of Randy.Dunlap about "EHCI errors in 2.6.8 (could be a patch mistake)". I replaced cap |= 1<<24 (ver 2.6.8) with cap &= 1<<24 (ver 2.6.7) and all works fine. Strange thing: 24th bit cap in 2.6.8 are setup always and all other bits are untouched. In 2.6.7 all bits are cleared expect bit 24. ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
