Kevin, Thanks. I saw that going through the kernel configuration just before you posted the reply; I was going to correct myself but you beat me to it. Everything works now. Does OTG work on the DVEVM? Thanks.

DIV { MARGIN:0px;} 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. Kevin From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andy Ngo Sent: Wednesday, March 14, 2007 7:40 PM To: [email protected] 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?

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]/msg01652.html) After applying Zheng's patch, I was able to use my flash drive and also a USB-to-ethernet dongle.
