USB Jtag Adaptors

this page is for usb realted jtag information and designs

i know that there was a lot of work at looking at using the USB method but it seems to be speed limited that has only managed to yeald designs capable of about 5 to 6Mhz in practice

so still not as high as the needed 25 to 30Mhz

as with the parallel port method i have left this section here because it is still usefull for programming and other jtag functions that will be of interest to many

there also seems to be software ip issues with the use of these usb devices

.... no designs entered at the moment feel free to add any .....
