Subject: usb-redir: Return babble when getting more bulk data then requested
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=2979a36183a3902cd75665e7c6bbc8668668fd17;p=qmiga%2Fqemu.git

usb-redir: Return babble when getting more bulk data then requested

Babble is the appropriate error in this case (rather then signalling a stall).
