From: Bandu on 22 Sep 2009 06:02 Hi, I'm developing multi port USB to serial driver. I got a problem on some PC, I got a problem that IOCTL_INTERNAL_USB_SUBMIT_URB (vendor request) call didn't return until I remove the USB device. It is not happening on every port. What would be the reason that cause IOCTL_INTERNAL_USB_SUBMIT_URB (vendor request) to get stuck in USB hub driver? Regards, Bandu
