it waits for 0x400 (timeout value counter) read access, then exit

It means the PHY works abnormal, would you please check the related
PLL is configured successfully?
I suppose yes, the PLL is configured in the right way (anyway I do not touch any
known register neither in the linux kernel, neither in the barebox and/or
bootlets), because the subsequent boots are running fine (at least the 90% of
the times)
I mean check PLL configuration runtime and see if it is the reason.
You mean check the PLL Configuration for USB1 Host Controller? Which
register or registers' set are you referring about?
Besides, if bootloader usb works ok with continual warm reset tests?
On bootlets and Bootloader THERE ARE NO USB SUPPORT activated, so I
cannot claim "bootloader usb works".
Or are you referring to the USB downloader (BootROM) features?
It is connected to the USB0 port (microUSB) and this port *HAS NEVER
DEACTIVATED OR NOT WORKING*...
