I would actually be really glad if you could test plain u-boot-usb/master and see if your USB problem is present there. Also, it would be really nice to isolate the sequence of commands which triggers the bug, so we have a proper reproducible testcase.
Anyway, this thread is not a place where I would like to discuss this. This should be discussed in the "original" thread, that is:
Subj: [PATCH] usb: ci_udc: fix interaction with CONFIG_USB_ETH_CDC
I cloned u-boot-usb/master and tested it. I am running "tftpd rootfs.ubifs" several times. Here is the log (I shortened the loading process bar):
[...]

The error always appears after calling tftp the third time! The first two runs work fine, but the third one always fails. I run this test about 20 times.
And finally, what is the contents of 'rootfs.ubifs' ?
Best regards,
