Hi,
(much better, thanks a lot. If you decide to send patches, you might
want to avoid format=flowed btw ;-)

I have report from other people about the same. MUSB driver isn't really
good with high-bandwidth ISO as of today. To get it fully working, you'd
also need double buffering and I'm not sure how that's supported on the
host part of the driver.
Which CPU are you using BTW ? and more importantly, which version of
MUSB RTL ?
Hi, the cpu that I'm using now is the TI OMAP 3430 SoC 600 MHz ARM Cortex-A8
3430 uses RTL 1.4, if I remember correctly. There's a register to read
the revision ;-)
CPU 430 MHz C64x+DSP. I tried dmesg but there wasn't written the version,
anyway it should be version 6.0 musb-dma otg. I really need this device
working (even 1 frame/second).. The problem as I said, I don't think is the
framerate.It gives me the I/O error (not enought bandwitdh) during the
initialization phase, before setting the framerate rate.
Yeah, could you do a little favor ? run the commands below and the dmesg
output after you see the failure:
(cable disconnected)
# dmesg -c
# echo 5> /sys/modules/musb_hdrc/parameters/debug
(connect cable, cause the failure)
# dmesg>> dmesg.txt
reply this mail with the dmesg.txt attached :-) If you're using e.g.
minicom, you can save the output of the serial terminal, that'll do as
well.
Hi everybody,
The output of the dmesg before plugging the cable and executing the program
is:
http://pastebin.com/Gj92qAWd
The dmesg output after is:
http://pastebin.com/gZ0DjRmB
I have not found any RTL string in the dmesg output.. I don't know why but there isn't..
The kernel is: kernel-power-2.6.28
