I'm using 2.6.20-rc5 . (.git/refs/tags shows v2.6.20-rc5 as last entry).
Are you loading all the necessary modules. For me, usbcore is statically linked
and then after boot I load below modules (in that order)
musb_hdrc.ko
scsi_mod.ko
sd_mod.ko
usb-storage.ko
I tried in evm kernel also _without_ Zheng's patch and it worked for me. Try
removing this patch.
I would suggest you to use a _fresh_ kernel, no extra patches applied.
Thanks

Kevin,
Yes, I've switched the jumper to host mode (pins 2 and 3) a couple weeks ago
when I tested the Montavista version a couple weeks ago (had to patch it with
Zheng's patch) and it worked fine. And yes, I configured the kernel to be in
host mode not peripheral mode which I had before which you corrected me a few
emails ago (when there were no USB activities). I see USB activities but
they're errors:
usb 1-1: new high speed USB device using musb_hdrc and address 3
usb 1-1: string descriptor 0 read error: -110
usb 1-1: string descriptor 0 read error: -110
usb 1-1: string descriptor 0 read error: -110
I loaded the Investra controller driver module (musb_hdrc) as well as any other
needed modules (usb_storage,
scsi_mod). I tried all combinations of kernel builds (usbcore as module and
as static, musb_hdrc as module and as static) and I still get the same errors.
Well, I going to re-download the current GIT tree again and redo this.
***Sigh****
Regards,
Andy

Unfortunately,
I still can't get the USB to work, even when using your config file. Do
you
remember
which version of the GIT tree you got? Here's the list from the
site:
Andy, I just tested host mode on
the current git tree and it's working fine. After booting, I 'modprobe
musb_hdrc', then plug in the USB key. It automatically loads the
usb-storage module and detects the disk. For the .config, it's the default
config, except for switching the Inventra to host mode instead of peripheral
mode.
Are you sure you have he jumper set
for host mode? The jumper next to the USB connector should be on pins 2-3
for host mode. I believe the board ships with it on pins 1-2 which is
gadget mode.
Kevin,
how do you get a specific tag (version) of the GIT tree?
Given a tag (ls .git/refs/tags
for the tags), you can checkout that tag on a new branch. To see existing
branches, do a 'git branch'. Then create a new branch:
$ git checkout -b my-dev-branch
v2.6.19
$ git branch
master
*
my-dev-branch
old
origin
I'm not sure this wil be much help
to you though since I have not been tagging the tree at the davinci merge
points.
Kevin
