Hi,
I was quickly scanning the BlueZ mail archive and found a few
comments regarding the support of Zero Packet with uhci.c. Johannes,
that is mostly for you ;-)
First, I never updated the comment on top of irda-usb because
I never got it to work with uhci.c. I was waiting for feedback from
other people before pointing the blame.
Well, I know that my hardware is buggy (it's the VIA
variety). Moreover, some people consider the usb-irda driver and
hardware to be evil (and they are mostly right). And my PC is very old
(dual PPro 150 MHz). So, I didn't want to point to finger too quickly
at the poor Johannes.
Know that at least somebody else has reporduce my problem with
a different harware and driver, I feel a bit better saying that there
must be a bug in uhci.c.
Johannes, if you have any patch, I'm willing to try it.
Jean
