Hope you feel much better soon Jean

Take care

Without decoding the software there is also no way to know if that is a host that is attached externally either. Or like you said it could have been a host chip that was in hardware that was not released and was on the internal bus. If the complete drivers were there and we could hack in the hardwar...

Yes rs485 is differential but it is still a serial protocol.

I had never given the vendor specific pin any thought. I applaud your
investigative intuitiveness.

I know exactly what you mean. I have a tendency to try and make things simplistic so that more people can follow what is being discussed. If we strip away all the layers of protocol and software USB is exactly what it's name says Serial Bus. I have long suspected that there is a trigger in the PSP f...

Yes the GPS is a host that sends serial data over the usb lines If you control the software at both ends you can ignore the protocol that should be run and run your own protocol. I have the source to the gps software that runs over the headphone serial port. It does normal serial gps protocol, my as...

To communicate on the USB bus you have to have a Host and a slave. You can only have one host but you can have many slaves. The host controls all communication on the bus just like a traffic cop. It tells the slaves who can talk and when they can talk. A slave can not talk to a slave, for instance i...

both the slim and the phat

I have tested both with 4.1 m33 software

I will look and see if I can find a PSP connector socket. Then all the pins can be brought out to the interface and you can then plug in the monitor cable so you do not lose that capability.

I am doing the drivers for three gamepads: Xbox 360 Wireless with chatpad keyboard and headset microphone PS2 / PS3 Wireless gamespads with rumble Logitech Wingman wireless rumble gamepad After the base gamepads are supported then I will take the left and right audio into two of the A/D converters o...

If you want a real leg up with working with the AT90USB familly processors then you need to go to MyUSB. It gives you a fully functional USB host stack for these processors. All my code is built on these as a base. There are fully functional demos of several HID devices as well as mass storage devic...

Well here is the proof of concept you have been waiting for This is the prototype USB Host to serial interface http://mysite.verizon.net/restxsa0/Serial.jpg This is a AT90USB1287 chip from Atmel. IT has not only a standard USB device interface but it has the USB Host interface. This is their prototy...
