Is there a way to slow down the USB Blaster Cable operation?

Hi,

I had some similar issues with the JTAG interface on an older board not being routed "as it should", ending in noise and failures with the high-speed USB Blaster. The JTAG operated well with the slower one Byteblaster MV. My question on slowing down the USB Blaster was neglected - no way to adjust speed...

But... who knows, some years have past since my request..
