Hi,
 
I am trying to implement USB mass storage capability to read from a CF
card on the EVM, using the original kernel version 2.6.10 distributed by
TI. Everything is working except it takes 20-30 seconds for Windows to
assign a drive letter to the device, even though the USB mass storage
device under the USB section and linux file-stor gadget usb device under
disk drives appear almost instantaneously in device manager. I found two
previous threads that relate to this issue:

http://linux.omap.com/pipermail/davinci-linux-open-source/2007-March/002
786.html
 
I tried both approaches, but saw no improvement. Debug output shows that
the program is stalled for a bit, toggling between the
FSG_STATE_CONFIG_CHANGE and FSG_STATE_DISCONNECT cases in the
handle_exception function of file_storage.c. If anyone has found a
solution to this problem, please kindly advise me on how I can resolve
it. Your assistance is sincerely appreciated.
 
Thanks,
 
Jenny
