Hi,
I own a Neo 1973 GTA01 BV4 and averything is working fine to download
load kernel and filesystem to SD and then run it.
I need to switch usb to host and for this I follow this procedure:
http://wiki.openmoko.org/wiki/Neo1973_USB_host
I patch a 2.6.22.5 kernel following procedure from
http://wiki.openmoko.org/wiki/Kernel. Everything seems ok as the file
/sys/devices/platform/s3c2410-ohci/usb_mode| |is present.
Unfortunately when I switch to usb host mode I get the following
messages in var/log/messages:
Jan 22 13:38:40 fic-gta01 user.warn kernel: s3c2410: changing usb to host
Jan 22 13:38:40 fic-gta01 user.info kernel: usb 1-2: new full speed USB

Jan 22 13:38:43 fic-gta01 user.err kernel: usb 1-2: device not accepting
address 6, error -62
I also made the following tests:
- modification of usb-modeswitch patch with GPE9 instead of GPE5: same
error messages
- I have also tested the following patched kernel:
http://celtune.morb-design.com/uImage-2.6.22.5-moko11+svnr3238-r10-usb-host-neo1973.bin
with modules-2.6.22.5-moko11+svnr3238-r10-usb-host-neo1973.tar and
OpenMoko-openmoko-devel-image-glibc-ipk-P1-Snapshot-20080120-fic-gta01.rootfs.tar
without any success.
Does somebody know what I missed?
Christophe
