Brian,
I have encountered the same problem. I'm running 2.6.23-davinci kernel and
trying to config
EVM as a USB host. I can read/write data to EVM board. But when i copied a
large size file,
some errors will appeared. I turned on the kernel debug and usb verbose debug,
some error messages like
this:
I don't know why command_abort called? and why it complained *Device offlined *?
I wonder if you have solved this problem?
