FreeBSD t43.nbttech.com 9.0-RC1 FreeBSD 9.0-RC1 #0: Tue Oct 18 18:30:38 UTC 2011 root at obrian.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC i386
On my machine running 9.0-RC1, updated from 8.2 via FreeBSD-update:
When running "usbdump -i usbus4" and connecting any USB device so far (memory, iPhone, 3G modem), it just hangs and doesn't output anything. Closing it with ^C is not possible, only ^Z and kill %1 is possible.
ktrace on usbdump shows that it is reading properly.
Running Wireshark on usb04 shows that frames are being received.
Running usbdump on a file captured from an old machine (FreeBSD X.x.x.x 9.0-CURRENT FreeBSD 9.0-CURRENT #0 r224195: Tue Jul 19 17:45:03 CST 2011 X at X:/usr/obj/usr/src/sys/GENERIC amd64) shows the output as expected.
Running usbdump on a file captured on this machine doesn't output anything, but can be aborted with ^C.
I have uploaded a tar ball at http://www.mavetju.org/~edwin/usbdump-problem.tar.gz with in it:
- output of trace in ktrace.out
- iphone.cap of when it doesn't work.
- usbdumptest from the old 9.0-CURRENT machine.
