Hi there!
This mail is mainly directed to the couple of guys developing a driver
for the isp1362 or isp1162 philips chips. I am one of them now :)
I am a colleague of torsten and we both are desperately (:-)) trying the
here and private exchanged patches vor the mentioned chips into a
2.6.10-rc2 kernel tree.
Especially I mean the stuff Olav send to Torsten regarding isp116x
incorporation with a dozen of #ifdefs :)
As you know, the usb changes between 2.6.9 and 2.6.10 are quite huge,
hc_start and hc_reset are gone now :( Sadly I need other features of
this new kernel tree, so we have to go for it. We are know at the stage
where the kernel tries to get info out of the HC when a USB device is
plugged into it.
I wonder mos about two things: What is a reasonable setup for
dev->istl0_queue.num_bufs = dev->istl1_queue.num_bufs = 0; //4;
dev->intl_queue.num_bufs = 0;
?
dev->istl0_queue.num_bufs = dev->istl1_queue.num_bufs = 2; //4;
dev->intl_queue.num_bufs = 4;
gives:

Is that reasonable or complete BS? I really don't know, because
c0342784 and c0342764 seems bogus to me because shouldn't there be a
space of 512 bytes between the values?
This one is for you, who are experienced in the driver, you should
recocnize your own debug output (torsten and me had printk's every
second line until today :/):

This shows our 1161a1 when an usb-storage stick is plugged in.
The Badness
Badness in isp116x_recv_queue at drivers/usb/host/ohci-isp116x-emu.c:594
is:
WARN_ON((!(__isp1362_read_reg16(dev, HCuPINT) &
HCuPINT_ISP116x_AIIEOT)));
May be someone knows what is going wrong there. I am trying to
understand myself until then :)
May be someone sees an obvious bug we triggered or incorporated into the port to
2.6.10. If not, don't waste your time, we have to bite through it and
understand more from this usb driver stuff.
Kind Regards, Konsti
