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-

Using usb_ether device
TFTP from server 10.0.0.1; our IP address is 10.0.0.2

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.

... 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,
