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):
[...]
     => tftp rootfs.ubifs
     using ci_udc, OUT ep- IN ep- STATUS ep-
     MAC 00:19:b8:00:00:02
     HOST MAC 00:19:b8:00:00:01
     high speed config #1: 2 mA, Ethernet Gadget, using CDC Ethernet
     USB network up!
     Using usb_ether device
     TFTP from server 10.0.0.1; our IP address is 10.0.0.2
     Filename 'rootfs.ubifs'.
     Load address: 0x40008000
     Loading: [snip]
       ##############################################################T ###
           [snip]
           1.7 MiB/s
Here it's 1.7MB/s ...
Sometimes I get a timeout "#T " while loading, which slows down the transfer rate. It is not always the case.

     done
     Bytes transferred = 13205504 (c98000 hex)
     => tftp rootfs.ubifs
     using ci_udc, OUT ep- IN ep- STATUS ep-
     MAC 00:19:b8:00:00:02
     HOST MAC 00:19:b8:00:00:01
     high speed config #1: 2 mA, Ethernet Gadget, using CDC Ethernet
     USB network up!
     Using usb_ether device
     TFTP from server 10.0.0.1; our IP address is 10.0.0.2
     Filename 'rootfs.ubifs'.
     Load address: 0x40008000
     Loading:
     #################################################################
           [snip]
           5.6 MiB/s
... and here it's 5.6 MB/s ... that's weird.

[...]

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' ?
It's an rootf ubifs filesystem. I also tested other files. One small u-boot.sb file with a filesize of 400 KB and a 62 MB compressed ubuntu core file (ubuntu-core-14.04-core.ext4.gz). For all I get the same result.

Best regards,
