Hi, When using EHCI host, there seems to be no PING token issued before the mass storage CBW is issued on the USB Bulk OUT EP. There are some USB disks which are not responding to CBW sent to them even after issuing mass storage 'reset' request and clearing any EP stall (when using the EHCI host).
Is it required by some USB disks to send a PING token before issuing a CBW on the USB Bulk OUT EP? If it is required, should u-boot EHCI host driver be issuing a PING token before CBW are sent on bulk out EP? Thanks, Thomas. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
