hi...
the problem is the uhci.c in
2.4.18 has far too many differences compared to that in 2.4.2.
so if a patch is created and applied it would not
compile in 2.4.2.
is anybody aware of the exact
kernel version where the uhci bulk message problem was solved...
that way i can probably generate a valid
patch...
yea aggreed...forgot to mention
that it's fixed in 2.4.18...sorry about that...

Then you can probably generate the patch you need by using
"diff -u".
$ diff -u 2.4.2/drivers/usb/uhci.c
2.4.18/drivers/usb/uhci.c > PATCH
$ diff -u
2.4.2/drivers/usb/uhci.h 2.4.18/drivers/usb/uhci.h >> PATCH
By
the way, when you know "it's already fixed in 2.4.18", it's
worth
mentioning that in your initial "problem report" ...

driver problem:OHCI vs UHCI
hi..
thanx...infact i've tried it with 2.4.18 and the driver works
fine...
but we have a specific requirement for the
driver to work on 2.4.2...if u are aware
of any patch that takes care of
the UHCI related problems for 2.4.2,can u suggest
the
same...
we infact managed to tweak around the uhci
code(in the bulk data portion) in 2.4.2 and made
the driver work,but it
would be ideal if we can get our hands on a patch that addresses
this
problem...
thanx in advance...

I hope
you're aware of how old that kernel is ... try
something more
recent, AND try both UHCI drivers.

USB driver problem:OHCI vs UHCI
hi...
We are developing a linux usb device
driver for usb adsl modem.
We are facing some
problem.
While our driver is working well
for OHCI hostcontroller (SiS, Compaq chipsets), it is not
fully
functional with UHCI host controller(VIA
chipset).
The problem seems to be in the
data receive path.While testing with ping, we found that all
ping
requests are reaching the destination but there is substantial loss of the
ping responses.
Is there something different
that we need to do in configuration for UHCI, or is
there
something
else that we are missing.Is there any known
problem in UHCI in 2.4.2.
We are using
redhat 7.1 linux 2.4.2 kernel.
Thanx in
advance.
regards
avinash
