 Hi,
 
 The BULK transfer stops by a stall. I suspect the UHCI is receiving more
 data than it can, and is hardware programmed to stop it looks like. I
 can't change that behaviour. It is not a bug in the FreeBSD USB driver I
 think.
 
 Try this patch to /usr/ports/devel/openocd/
 
 make extract patch
 
 ee ./work/openocd-0.5.0/src/jtag/drivers/jlink.c
 
 Uhh, may I use Vi? :-)
 
 Change:
 
 result = jlink_usb_read(jlink, in_length);
 
 Into:
 
 /* must read at least one packet at a time! */
 result = jlink_usb_read(jlink, in_length + ((-in_length)  63));
 
 Then re-compile and try again!

 Ok, I'll try that patch(~ sunday eavening, I'm out of town currntly),
 but it adresses the problem with openocd. ( which is good anyways).
 I is still a bug in FreeBSD's driver that there is now way to
 wake up the controller again and I think that should be changed.
 (please remember, most Kerenels are running with compiled in drivers, so
 thie singe solution is a reboot to reactivate the controller.
 I dont know that much about USB, but I sure that FreeBSDs behavior in this
 case isn't that what we really want. I think usbconfig -d ugen1.1 reset
 schould be made working..

I will think about it. Currently a suspend and resume will do that, though it 
might be an idea to allow that runtime using usbconfig.

USB UHCI Problems on 8-Stable

2012-03-15 Thread Holm Tiffe 
Hi,

For some time I had problems with my Cam (Olympus FE-230), it wouldn't get
recognized again after unplugging it from the USB Connector.

Now I have a very similar Problem while trying to get an J-Link V8
compatible Jtag debugger working in conjunction with openocd.
Maybe there are bugs in openocd, but the bigger ones seems to be in
FreeBSDs USB drivers.

In the meantime I've cvs-supped to 8.3PRERELEASE (yesterday) built world
and kernel. I've commented the ?hci drivers out of the kernel config and
set USB_DEBUG.


At fist please Cc me, I'm not on freebsd-usb.

Hi,

Could you log the USB traffic on the UHCI controller using usbdump ?

It would be interesting to see what is going on.

Have you tried using an external High-Speed HUB?

Here is the dump: http://www.tiffe.de/other/usbus1.dump

This is connecting the J-link, starting openocd twice, removing 
and reconnecting the J-link followed by a kldunload uhci.

Can't provide a dump while kldloading since usbdump stops when the driver
is unloaded.

I have no Highspeedr-Hub so this was a direct connect. Results are the same
regardless whcih interface is used.

Holm
