Randy,
That patch did nothing to fix the system hangs I see with the
Lucent OHCI controllers. However, I just tried the pre3-6 patch
and the most resent OHCI driver changes do address this problem.
Instead of a hang, I now get the following when plugging a TI
7 port hub into a Lucent USS-312 eval card:
hub.c: port 1 connection change
hub.c: portstatus 101, change 1, High Speed
hub.c: portstatus 103, change 10, High Speed
usb.c: USB new device connect, assigned device number 2
usb-ohci.c: OHCI Unrecoverable Error, controller disabled
usb_control/bulk_msg: timeout
usb-ohci.c: unlink URB timeout!
usb.c: USB device not responding, giving up (error=-108)
hub.c: hub: disabling port 1
This is a definate improvement! Now to find out how to recover
from the "OHCI Unrecoverable Error".
Also, do you know why the Linux USB mail archive page has not
received any new posts in the last day and a half?
Thanks,
Bob
