I am working on iMX6 which has YOCTO rocko with framebuffer distro.  And i am trying to detect a flash USB drive and USB card reader in U-Boot but it is throwing an error of EHCI timed out on TD - token=0x80008c80 ."unable to get device descripter" . This is when i am trying to detect it using USB start in the uboot itself. Also when i give the command USB reset and then try to again read the USB it is detected. 


I have tried to also increase the detection time of the USB and also the number of retries. As sometimes some flash drives need a little bit more time for them to be detected. But no response yet.
