Because it's not part of the USB 2.0 spec. It is defined in the USB Mass Storage Bulk-Only Transport spec. > Can anyone here tell me what kinds of situation the host will send > the bulk reset request? It depends on the host. As far as I know, a Windows host will never send that request. Recent Linux kernels do a port reset, but will send a bulk reset request if the port reset fails. Older Linux kernels send the bulk reset request first. The resets are sent whenever an error occurs in the communication between the host and the device.
