Folks, I have just puckered up courage to share my thoughts and risk ridicule...
Well I have jasper 512nand. As we know it is a ballache to dump using LPT so 'high performance' olimex lpc2148 usb now supported in nandpro2b. I'm guessing the nandpro performance is all down to port throughput data rates, whereby USB has 12Mbps data throughput compared to standard parallel port throughput rate of 150kbs.
But if it is ALL down to LPT port data thru put limitations, then why use the complicated olimex usb lpc setup? Why not simply connect the male db25 connection from the xbox mobo to a female db25 parallel printer cable which has a usb connection to pc? Or would a Parallel Printer Port Cable 25 pin female connector not be compatible with nandpro2b libusb driver? If not, surely we could find a cable driver that would work with nandpro.
Using this simple single usb Parallel Printer Port Cable 25 pin female connection would sure make life easier for big blockers and a lot cheaper to boot!
I am conveniently ignoring any of the voltage considerations on the premise our good friend mr resistor could help us it out if required.
PS No doubt this idea has been thought off before but I thought I'd ask the gurus anyway...
The best way is to dump the nand completly overnight a few times, Then flash Xell onto it and boot into linux and dump or flash your nand. It will dump 512 in about 2 minutes.
