Hi,
I am testing the USB infrastructure on a Rockchip RK3328 based roc-rk3328-cc target.
The USB tree on the device is as follows:
=> usb tree USB device tree: 1 Hub (480 Mb/s, 0mA) u-boot EHCI Host Controller
1 Hub (12 Mb/s, 0mA) U-Boot Root Hub (OHCI)
1 Hub (5 Gb/s, 0mA) U-Boot XHCI Host Controller
1 Hub (480 Mb/s, 0mA) U-Boot Root Hub (DWC2)
For some reason I am unable to detect storage device on DWC2 when two USB drives are simultaneously connected on EHCI and DWC2. Though it shows 2 storage devices when i do a "usb start/reset" and it gives usb_mass_storage.lun0 failed message as shown below.
=> usb start starting USB...

However, an interesting observation is that if i disable CONFIG_EFI_LOADER, then I am able to detect the storage devices without any usb_mass_storage.lun0 failed message:

Please share you thoughts.
