Details:

I wrote a driver for Digilent's USB JTAG/ISP programming cable, and would
appreciate your considering it for inclusion in avrdude. This driver handles
two versions of the programmer. It is based on the code for the usbtiny, and I
found the usb packet format by using the kernel logging module "usbmon". I
have tested writing/reading to flash and eeprom for the mega64 and mega168 and
it seems OK.

The patch also includes changes to the documentation. Feel free to edit if
you like.

I needed to make a slight change in avr.c. For this programmer, the paged
write command only works with paged memories, because it can't add delay
between individual writes. So, I'd like to fall back to the default avr_write
function for non-paged memories. In order to make this work, the counter "i"
in avr_write needs to be changed from "unsigned long" to "long". I think that
matches the original intent of the code:)

The patch is relative to svn trunk rev. 819

thanks
Dirk
