>Description:
A change, apparently in later FBSD 8.x and in FBSD 9.x, causes usbus[0-n] 
devices to appear as network devices.  They do not show up in ifconfig -a but 
the do show up in netstat -i.

This causes a slowdown and errors at startup when both ifconfig_DEFAULT="DHCP" 
and synchronous_dhclient="YES" are set in rc.conf:

usbus0: not found
exiting.
Starting Network: usbus0.
usbus1: not found
exiting.
Starting Network: usbus1.

etc.

This has been mentioned in various places:

>How-To-Repeat:

ifconfig_DEFAULT="DHCP"

isochronous transfer for UVC camera

2012-10-29 Thread SAITOU Toshihide 
I'm trying to get the streaming data from the UVC camera, but isochronous 
transfer callback isn't invoked. Is this lack of parameters to be set or wrong 
coding for my isochronous transfer?

Hi,

The packet length is not this value I think.

The 0x1000 is part of the packet multiplier for High-Speed USB's 
wMaxPacketSize.

It is (1+2) * 0x400. Try that and see what happens.

Also there is usbdump -i usbusX -f Y -s 65536 -vvv, which will show the actual 
traffic.

Thank you for your quick response.

I can't use the FreeBSD now so I will try this tomorrow.  But Mac OS X 10.6.8 
with libus 1.0.9, callback is not invoked too with some combination of the 
value below:
