Andy,
The default defconfig for DaVinci has the USB driver built as a module
and more importantly for you case, it defaults to be in USB peripheral
mode (not host mode.) Re-configure your kernel selecting host mode
under USB support --> Inventra ... -> Driver mode.

Subject: USB port not working in GIT kernel?
Hi,
After switching over to the GIT kernel, I can't seem to get the
USB host port to work anymore. In the Montavista kernel, I was able to
apply a patch by Zheng to get it working (I was able to hook up a USB
thumb drive and a USB ethernet dongle and operate them fine). In the
GIT kernel, I see no activity (I manually loaded the usb_storage.ko and
pegasus.ko modules). On bootup, the kernel log shows that the interface
was registered:
...
usbcore: registered new interface driver usbfs
usbcore: registered new interface driver hub
usbcore: registered new device driver usb
...
Yet I get no USB activities. Here's a list of the modules
loaded:
# lsmod
Module Size Used by Tainted: GF
pegasus 27312 0 - Live 0xbf061000
mii 5888 1 pegasus, Live 0xbf05e000
usb_storage 37924 0 - Live 0xbf053000
scsi_mod 107592 1 usb_storage, Live 0xbf037000
dsplinkk 69176 0 - Live 0xbf025000 (F)
cmemk 13468 0 - Live 0xbf020000
usbcore 126560 2 pegasus,usb_storage, Live 0xbf000000
Anyone else has this problem? Thanks.
Regards,
Andy

Jitendra,
Apply Zheng's patch and it should fix your problem. Refer to
the link below to patch your kernel.
(http://www.mail-archive.com/[EMAIL PROTECTED]

After applying Zheng's patch, I was able to use my flash drive
and also a USB-to-ethernet dongle.

Andy

Thanks a lot in advance.
