Practical design and implementation considerations ufs3 usb driver
A robust UFS 3.x USB driver requires UASP, efficient command queuing, and careful power management. On the host side, standard Linux SCSI/UAS drivers suffice; on the device side (embedded), a custom USB gadget driver is needed for maintenance modes. To understand the driver requirement, you must first
